So many of these Active Vs Passive speaker reviews I have seen start with a premise of one is better vs another and then set out to try to prove it, Any Way They Can. 1) Most powered speakers don't rely on or have DACs in the speakers. Just an amplifier. But the ones that do, they do tend to sound pretty good. Some even come with a microphone to calibrate the speakers to your listening environment. Just like the tuning available on most surround sound systems. 2) I don't agree with "sending bass energy" to a tweeter etc. An active crossover will always beat a passive crossover unless you spend a much much more money on the passive version. Many hi-end speakers are designed for bi-amping because its a fact that having the amplifier only have to worry about and manage the impedance shifts of it's assigned drivers is very beneficial. 3) Comparing the flaws of inexpensive active or "powered" speakers with the benefits of hi-end audio gear is just marketing to make a sale. Assume a hi-end active speaker to have an equally worthwhile amplifier matched to it. The speakers ratings and sound depend on it. Measure apples to apples. A $2000 active speaker needs to be compared to a $2000 speaker And amplifier purchase. 4) The mix and match game. If you buy a set of passive speakers with a set of curves as to it's response values, that is only for that speaker. Now lets say as an example, you have speaker with a response of +- 3db 50 hz-20Khz. And you pair it with an amplifier, which will have ratings lets say 20hz to 20Khz +-2 db. If its +2 at 100hz and the speaker is +3db at 100hz, you now have +5 db peak at 100hz. Or who knows where. Creating the game of matching your amplifier(s) to your speaker. But, if you buy an active speaker with a ratings plot. (room involvement aside) that is the rating for the amp And the speaker. Because the manufacturer has taken care of that matching. That right there is a huge cost and time savings. Allowing more money towards room treatments and things to help your room give you better sound. If you really love playing mix and match, go passive. If you want the sound the way modern musicians hear it, active speakers are what most use. And they save time in finding what works best for your space and hearing. So yes don't buy a speaker with a built in DAC as the only input. Speakers that rely on a DAC for their crossover and frequency manipulation, will always be as they are. So yes, you get only as good as that system is. But hey, many people still buy gear from the 70's because they like the sound better. Some people don't like the extra detail from new DACs and class D amps. It's like watching 70s porn on a 75" OLED screen. Do you benefit from really seeing the close up razor stubble your 19" tube TV hid from you? But hey, if you have the money to let someone dittle with your speakers to try to get the extra 10% percent out of them, go for it.

I used passive speakers exclusively for the first many years of my listening life. (AV123 X-LS, pre-Encores, were my first nice speaker, and I've enjoyed a lot of Danny's designs since then, particularly the Strata Minis that I regret selling years ago). However, on pure sound quality alone, I'd put my Barefoot MM12 above anything else I've ever heard. I love ATCs and have a couple sets (active and passive) and the ATC SCM150A were excellent too, but I've yet to hear anything that bests the MM12 in pure detail and enjoyment. I love many passive speakers, but properly executed active speakers seem, almost by definition, to have a higher ceiling in terms of audio quality. Then again, I have zero background as an EE, just a guy who loves music and audio gear.

Barefoot MM12 - looks like a ton of drivers in a very compact box & an example of what can only be achieved in an active configuration - it's a bit strange however, as I can't imagine 2x12" per side in a near field application - this is full range output that's normally a floor stander - I guess there's Augspurger.....

Active setups are extremely useful for seamless blind A/B crossover testing. I've never had a noise issue because my amplifiers are what I use in my passive systems. I always high pass my dome tweeters with a 20uF cap to protect from any DC thump or crossover failure which solves any low frequency noise Software DSPs with a quality DAC have a lot of design flexibility. Notching and shaping I find typically easier with DSP over passive. Time delay is much easier in DSP than ladder delay in a passive if you are set on symmetrical slopes and a flat vertical baffle. I've built great sounding speakers both passively and actively. I can think of equivalent pros and cons for each

Pro Audio has left passive years ago. The flexibility, dynamics, and clarity of active systems are unmatched as compared to passive. Cheap and cheesy is bottom end no matter active or passive.

Wow, a wealth of information. I never thought of what the rest of the spectrem of say a woofer amp or the tweeter amp on a biamped system is sending to it's driver. I have to re-think my system.

For quasi mastering he had these cool looking Miller Kreisel speaker system that had a subwoofer. I asked him why most studio monitors were always active and he explained that in a small control room full of gear, small powered nearfield monitors were more convenient because you don't have an extra amp and an extra set of wires taking up space etc... He explained that for mixing, his main concern was hearing each track before and after processing (I was blown away by the fact that he relied on the VU meter more than anything else). It was educational to discover the distinction between mixing and mastering and their respective intent. My take away was that active nearfield monitors just aren't intended for home hi-fi etc... Just as a side-note, this was in the early nineties where there weren't any computers, just ADAT tape machines, and lots of racks and mixing consoles.

No, he did not. Yes, a good engineered passive speaker can easily beat bad engineered bi-amp or tri-amp system. However, good engineered tri-amp system will always triumph over passive system. The main problem here is the market demand. For the engineering point, it is extremely easy to implement variable active crossover in DSP section of a receiver and provide bi-amp and tri-amp speaker out and it cost almost nothing extra for the manufacturer. Having said that, I don't think it will happen in foreseeable feature as this will create confusion for the majority of the population.

You certainly explained why fully active speakers have not caught on with audiophiles, but a active crossover with carefully optimized filters combined with excellent amplification seems to offer real performance advantages. I like the approach that Bryston has taken with its active systems where the speakers, amps, crossover and dac are all discrete and easily upgradable components. Thank you for a very informative and thoughtful presentation.

Hello there I e been playing with speakers since grade 5 , I have gone down a little different path .it started at car audio in the 90s .got my first rta then made one of my car systems totally flat as per rta , pushed a cd in and yuuuk it really hurt .then made a lot of home audio ,and now I’m in the pro audio and a lot more yuuuk especially with active and plastic boxes . So I’ve been. Building wood boxes with high power custom crossovers they sound great . Most people don’t know good sound until they hear it .oh well just wanted to say hi keep up the good work .

I haven't heard the 19/20 ATC's but I did get to hear both the SCM 40 and the SCM40/A and there was a noticeable improvement in sound quality in the active version. I can't remember what amplifier was driving the passive version but it was in the €2,000 to €3,000 range, the actives had greater frequency response and clarity over the passives, reviews into both speakers also highlighted similar differences. Unfortunately I couldn't afford them but I eventually settled on Focal Trio 6 active speakers. Before I heard the ATC's I wouldn't have considered actives but doing so gave me the best sound quality for the budget I had.

Moore’s law hit the wall 7-10 yrs ago. My best sounding pc used a 2 ghz Pentium 4 single core cpu but was lost in a fire. My best DAC was a Pooge 5 Phillips 960 with a Phillips 1541 Crown DAC chip, also lost. BUT, I’ve not heard the Denafrips R2R type newer dacs.

Active has a larger potential than passive by being able to use separate purpose built amps direct-coupled to each driver element, no caps/resistors/inductors in between. In addition, we can in some applications use Phase Linear Filters (FIR), creating a phase coherent speaker which is superior to any passive approach. However, if low quality parts or done in wrong ways, the result is of course not satisfying.

Also with passive filter components there is the possibility to current drive the speakers ensuring lower distortion from nonlinearities in the actual drivers. When feeding them unimpeded with a voltage any nonlinearities in the voice coils will have maximum effect on the resulting current producing the sound. A lot of people miss this fact about passives. Also an unprotected tweeter fed by a fullrange to almost DC signal bandwidth can damage the tweeter with unintended hum and clicks/noice. I have repaired active speakers with blown tweeters because of glitching signal input connections causing hum passing directly to the tweeter.

This just boils down to "you get what you pay for". Some active speakers now cost thousands and you can be sure that the top end ATCs, PMCs, PSI audio and a whole host of other manufacturers aren't using the level of parts available that were available 20 years ago. However these speakers have a hefty price tag and I would suggest that newly designed passive in this case offers some significant cost saving advantages over either older active models or more budget level active equipment. Perhaps these older ATCs are still a better buy than some newer low-mid priced speakers.

I would like to have seen a “before” curve that Danny always shows when he performs crossover redesigns. I suspect the original actives was flatter that the passive redesign, which is an advantage of active designs. The “unwanted” frequencies Danny talks about, IF present are 80+ dB down from the normal signal and are simply a non issue. I’ve designed passive & active. Both can be excellent, both can be bad. An active system removes everything between the amplifier output and the speaker voice coil, so amplifier damping is optimal. When designing passive crossovers, the differences in one driver to the next matter greatly and can alter the response, so one speaker may not sound like the other. That’s why John Dunlavy tested every driver and carefully matched them to within 0.5dB. Then he tailored the crossovers for flat overall response. With active designs, variations from one driver to the next don’t affect the crossover point and therefore minimizes any effect in the sound.

We've made those comparisons. We took a full open baffle line source with open baffle servo subs and used it as a test bed. Slopes were matched digitally to the passive filters etc. And passive filters do not steal power, and at the quality level of parts we were comparing with they do not smear the signal. There was FAR more difference in DAC's being used then anything the crossover parts were doing, and the DAC's were using the same DAC chips. We were able to get the phase between the main speaker and subs dialed in more perfectly, and at times I thought their was slightly more soundstage outside the speakers. However, the differences in DAC's were still the difference. We used the same source feeding those DAC's too. The all passive design still won out in almost all areas. The other factor was that the all digital system used a LOT more amplifiers and cables making it a LOT more expensive.

Danny I don't find you to be typically biased, but I think you are unnecessarily biased towards passive crossovers. I have been running active for over 10 years but I don't have some cheap active speakers. You have upgraded the active crossover but you haven't similarly upgraded the active system to give it chance to out shine the passive once more. All of the configuration you are saying isn't available to active is available. Having active circuitry built into the speaker isn't the typical way that people do an active system, at least not anyone serious about active. You have a choice of high end active crossovers with quality DACs (mine uses something like 8 Burr Brown DACs), granted anything half decent is going to cost you very close to 5 figures by itself, and add a decent multichannel amplifier/s and you are definitely now well over 5 figures. So you can't compare what I am using with some budget active speaker. Nothing stops me swapping out interconnects, DAC, amplifier or speaker cables. So there is plenty of configuration options. Using the same amplifier on both active and passive you still have the advantage of the signal is given it's signal range before it is amplified which will give you a cleaner sound, since no amp is designed to be equally effective across all frequencies. On to of which you have a lot more channels with active so you have a lot more amplifier headroom per driver, which means that same amplifier isn't being driven as hard if it is only powering one driver.

One of the benefits of a separate amp per driver is that you don't need to have any binding posts at all (no binding post equal zero loss at the connection point that isn't there), I go straight from the amp to the driver (soldered connections), you also have the option of amplifying to suit the specific driver i.e. you might want a tube amp on the tweeter, but want a Class D on the woofer.

In the video you use a high pass filter to split the amplified output signal, and while this is a great way to split off a signal to the sub as you described in the video it isn't without its own problems to solve. Whether it is a separate sub or an additional woofer inside the cabinet, you are still adding an additional component to the crossover which from my limited understanding of passive crossovers is still going to ultimately influence the overall crossover in the cabinet (just a geography thing). Most of us out there in stereo land couldn't even start to fathom what impact that might have from a performance stand point on the rest of the system. decades ago I wrote a software program to design crossovers, but that still gives you nothing more than a starting point, it takes your level of experience to know where to go from there. Active simplifies things for the "novice" like me. You are sending only that frequency to the driver. All of the crossover slopes, filters etc etc can be applied quickly in the software to evaluate changes without a large amount of time in between listening tests. While I believe it may be possible for a quality passive crossover to sound better than an active setup, it certainly won't be performed by the novice or even intermediate user.

Actually when splitting the signal to the sub and main speakers using an inline passive filter installed prior to the amps only uses a very small value cap as a filter. So that cap can be very high quality and very transparent. So no other high pass filter is needed in the speaker. That cap filters out the lower region very cleanly. So it does not affect the rest of the parts used in the passive part of the filter.

Active all the way after so many Listening sessions of self called passive High End gear from famous brands. There are way to many pros over cons when you go the Active, DSP based way.

Yes, sounds you are stuck in the speaker (as if everything should be in that box.) When having a full active system with external different amplifiers and DACs and you're not stuck at all and no drawbacks that you are mentioning. We remove that passive crossover that is the stupidest place to place a crossover if not you just want convince. But convince trumps most of the time. Convince is not sound quality they don't go hand in hand. When having a crossover AFTER we have made power amplifing. Then we must use huge passive components (caps, resistors and coils). Those components is between the power amplifier AND the driver. Stealing power, smearing and hindering the power amplifier to fully use it's damping factor and control the drivers. But if you have a DSP and fix the crossover in the low power domain it is more efficient and wiser. Yes you have a point if we put everything in the loudspeaker.. The down side is that we have to do the job as Danny does by determine where what and how much the crossovers should be. There is where the convince come into play. It is easier and more convinent to just by a passive speaker and be done with it.. But you don't learn and you miss out performance. Plus it is not optimized for your specific room and not your listening levels. So a separate DSP box that does all that Dany does in the passive domain and are also able to do SO much more than that (that also bring the sound quality to a untouchable level of performance that no passive crossover can match at any price.) And connect it to two separate power amplifiers if it is a 2 way. One for each driver. Then connect them to each of the drivers. That will bring superior quality and learnings for the audiophile. Plus adjustable on the fly depending on YOUR specific listening preferences (and not speaker designers) plus depending on listening levels. And on top of that that also leaves the passive crossover in the dust! Acustically adjust for your specific room and speaker placement (yes the passive crossover can't never offering us that.) But it is not convenient setup but the best of the best sound quality wise. That is also why the most expensive speakers have passive crossovers. When Elon Musk, Bill Gates, Jeff Bezos, Warren Buffett buying a HiFi system they have not the interest and passion like a audiophile to learn and make a perfect sounding system. They just point on the most expensive speakers and amplifiers and someone set the system up for them convinent and they're done. And it is convenient and third best option to by a speaker from Danny and just start enjoying the music but it is not the "best" that those speakers can sound in your room. But you got there with low effort.👍

We've done all of that stuff that you just said. We took a full open baffle line source with open baffle servo subs and used it as a test bed. Slopes were matched digitally to the passive filters etc. And passive filters do not steal power, and at the quality level of parts we were comparing with they do not smear the signal. There was FAR more difference in DAC's being used then anything the crossover parts were doing, and the DAC's were using the same DAC chips. We were able to get the phase between the main speaker and subs dialed in more perfectly, and at times I thought their was slightly more soundstage outside the speakers. However, the differences in DAC's were still the difference. We used the same source feeding those DAC's too. The all passive design still won out in almost all areas. The other factor was that the all digital system used a LOT more amplifiers and cables making it a LOT more expensive.

I saw a yowie once and was a like a redish brown wood case single standing with a sub at the bottom with 2 speakers above but 2 tweeters in the middle, what

In all fairness, Danny finds cheesy parts in most passive speakers, too. He has opened many people's eyes to the quality of crossover parts. However, many people lack the time, patience, or ability to modify passive crossovers or build active speakers. What is my point? Whether you decide to go with passive or active speakers, do your homework first. Ask the manufacturers questions about crossover parts/points/slopes, driver materials, cabinet bracing/damping, amps, sensitivity, impedance, radiation pattern, bass response, etc. If they won't answer, walk away.

Danny my good man,the short hair and close cropped beard are top notch 👍

The "pros" don't believe any of this, nor can they hear it. And the trend isn't only powered speakers but with DSP (ADCs and DACs for analogue inputs). For my computer, I tried a HEDD Type 5, MK II. It had detail but very high digital distortion. Again, the pros love this and jumped on me for my criticisms. So I bought a used pair of discontinue HEDD Type 5s (no DSP), which are very good and have no digital sound. My next move is to get an amp and ELAC Vela 403s.

For the longest time, I did not have active speakers, but did travel with passives, but used the amps installed in the studios. Amp/speaker combinations are thing, as you well know. I finally purchased a non-dsp'ed version of active speakers so I had a consistent listening setup no matter where I went. After retiring from that part of the industry, but still doing an odd gig here and there, I got rid of them. Well, did a gig at the Rose Bowl, which meant hauling up a really heavy amp with heatsinks tearing up my arms, up multiple elevators, with a pair of passive 2-ways. There, in a nutshell is why the Pro side of things uses actives. Ken Kantor built a pair of actives at NHT Pro with the amp and adjustments in its own case. Great idea. Didn't do well in the pro world. So, because of that, I invested in a pair of active monitors again, this time with dsp. Are they the last word in resolution? No. Can I hear what I need to make wise mixing decisions? You bet. That said, I do plan on buying another pair of active monitors, no dsp, no cheesy amps, and wise parts choices.

If implemented well, a passive crossover can help to provide a good sound from a capable loudspeaker. However the design of any passive crossover is, by its very nature, fundamentally limited and it can only act as a rather basic filter. Large capacitors, inductors and resistors combine to remove unwanted frequencies from each frequency band of the large loudspeaker-level signal in order to ensure the signal is suitable for the drive unit. Passive crossovers can therefore only ever give out a lesser signal than is put in, since each crossover absorbs - or worse, sometimes reflects back into the power amplifier - the parts of the signal that it filters out. Most of the energy that is prevented, by the passive crossover, from reaching the loudspeaker drive units is expended by the amplifier as heat. This inherent inefficiency can mean that, for some loudspeakers, a third or more of the power produced by the amplifier is wasted by the crossover. With the amplifier working much harder than is necessary, this greatly reduces the level of control that it has over the drive unit, adversely affecting the system performance. There is also the problem of the passive filter being connected between the amplifier and the drive unit. This means that the signal is impeded - an effect that is particularly prevalent with the bass signal. Another difficulty arises with the layout of the crossover: physical proximity of components to each other and to other metallic parts can lead to crosstalk (signal leakage from one part of the circuitry to another) and other unwanted effects, again compromising the performance. Since higher volume levels tend to exacerbate all the above problems, when a passive crossover is used, accuracy and power are limited and signal integrity is likely to be compromised.

@RacingAnt

All those points are valid, but mainly apply at lower bass frequency. Which is why the open baffle subs sold by Danny use active crossovers. The power levels at the mid to tweeter level are way lower, so the effects are less. Different solutions for different frequencies.

"a third or more of the power produced by the amplifier is wasted by the crossover." This is not correct at all, and easy to demonstrate. I can measure the output of a woofer played full range with no crossover and then with a passive filter. The only reduction in output form the filter comes in the form of the DRC of the inductor used. That is typically fractions of an ohm. So very little is lost. Also the slight rise in impedance doesn't make the amplifier work harder. Lower impedances demand more current and make the amplifier work harder. So technically the amp can be seen to work harder with no filter.

What would have been interesting is to upgrade the active filter with the same budget as the passive one and compare; not apple to apple in his video.

atc or psi are special actives... they dont have dac and are full analog. Another thing is genelec, kii tree, d&d... all digital there. Active done right can be better regarding xover and phase and getting more bass in small volume. Will be pretty difficult to find a proper passive match (quality and price) even to actual actives like those from buchard, kef or dynaudio.

Seems a shame to compare active vs passive crossovers with only a powered and active design built to a price point. It would be great to discuss the potential of each implementation. A comparison with a good speaker, with identical external power amps comparing only passive vs active crossver implementations where all other elements in the chain are equal. Active crossover design doesn't mean it has to be an all in one box speaker system. Removing any components between the amp and drivers with a digital crossover presumably would have advantages over passive? Yes more Dacs, Power amps, complexity and cost but it would be great to hear GRs view on the ultimate implementation of a speaker system.

And in the newer kit such as the Exaktboxes which take the linn proprietary Exakt signal from the streamer / pre stage, the Exaktbox acts as both DAC and active crossover with the crossover being selected in the configuration for the selected speaker model, the Exaktbox has multiple output for Bass, Mid and Treble for Left and right, which you send to your power amps and then to the speaker inputs. very good system if you dont mind having an all Linn system which clearly I don't and haven't since the mid 1990's. But i still learn a lot here and have been upgrading the XO's on all my passive surround speakers in my new Home Cinema, thanks to Danny's teachings. I'd love to hear his system and hear what I might be missing

We've done it both ways using the best passive and all digital filters. There are pros and cons to each, and it is easy to crush either with the other depending on implementation. It the end though, the top dogs are still using all passive filters and they are still our choice for best overall sound.

Most DSP active crossovers are mid-fi (miniDSP) or low end pro audio (Behringer, DBX) soundlkshit PC-based DSP XO, w/convolution, highend multichannel DAC is SOTA but big money and time Line level analog filters solve most of the problems you stated, like in Rythmik servo-sub amps, but setup/configuration not point and click so millenials "can't even" and they are the target audiophile market now.

Normally you never talk about the quality of amplification. You rely on the measurements of a passive speaker and design a new filter for better measurements and much more "clarity" But what amplifier do you use to test the sound quality and can every amplifier handle the possible complexity of your new design? In the beginning of this video you make clear that this active system with the cheap built in amplifier sounds better compared to the same system with a passive filter and a cheap amplifier. So I think a good sound quality is easier (and cheaper) to realize with an active system. Isn't it?

There is NO reason not keeping music as long as possible in the digital domain. Passive crossovers can be very good, just like vinyl can be very good, but digital is simply a dimension better. Kii Three and others show the way this WILL go, there is simply no doubt. Why are we even talking about differences in quality in amps, differences below 0.01% where the speakers have differences going upto 10% and more. Tolerances for passive crossovers are in the range of 1-10%.

Hi Danny :-) Of course I know that you are a big advocate of passive speakers and I don't blame you for that. But I feel like you are a little biased here. I see that you compare two incomparable things and forgot about passive shortcomings. You don't sell your things with an unlimited budget, right? The price must be one of the criteria. So let's compare. Could you take about 2500 dollars and make the entire passive system in such quality so that it is as good as active or better? This should be with speakers (DIY), amplifier, DAC, DSP (to your liking - maybe Minidsp?). I bet you can't. So when you say that in the future you can change things for the better - I can do it whenever I want, or when I need to move my speakers to another room. Because I can fix some things in the room for free in a few minutes. You can't do this with passive speakers. So please dont compare best things you can do yourself with passive speaker and industrial manufactured active speaker. Becouse its not fair. I expect a question about the shortcomings of passive system.

We;ve made those comparisons. If you want to really suck the life out of the music then use a MiniDSP. $2,500 might not even cover all the cables needed for an all digital system. With an all digital system you can't even come close. You need twice as much amplification and cable for a two way speaker, and three times as many for a three way speaker.

Besides durability it's hardly about amplifier quality anymore when there's DSP, room correction, drivers that do specific things (The rear drivers in Buchardt A500/700, the Dutch&Dutch 8c etc.) and other trickery that will leave passive systems far behind.

We've done all of that stuff that you just said. We took a full open baffle line source with open baffle servo subs and used it as a test bed. Slopes were matched digitally to the passive filters etc. And passive filters do not steal power, and at the quality level of parts we were comparing with they do not smear the signal. There was FAR more difference in DAC's being used then anything the crossover parts were doing, and the DAC's were using the same DAC chips. We were able to get the phase between the main speaker and subs dialed in more perfectly, and at times I thought their was slightly more soundstage outside the speakers. However, the differences in DAC's were still the difference. We used the same source feeding those DAC's too. The all passive design still won out in almost all areas. The other factor was that the all digital system used a LOT more amplifiers and cables making it a LOT more expensive.

Active all the way.

No way.

well this old active version has a flatter response graph than your so called new passive components upgrade with measurements. That speaker is old now, the new version has ATC's new 2 tesla tweeter, with newer upgraded components of their class A/AB mosfet amplification. The newer amplification has twice as much capacitor supply than this old one. Drive units can only handle so much power in active drive. Building the most expensive most powerful amplification you can, would absolutely do nothing for sound quality for their new versions, for active drive, as i said the drivers cannot handle more power than was designed for their active drive. ATC designs for the shortest signal path with the least components as possible with the lowest noise. They are a professional monitor tool to tell the truth of the signal path upstream, and not for catering to the whims of audiophiles musicality perversions. Only over built over specified amplification works with the passive version ATC's, because the 3 way ATC's can handle 1500 plus watts. Using far more overbuilt over specified power amplification for active drive does absolutely nothing for extra gains of supposed lower noise, extra clarity or power handling for the drive units . Obviously you think you know more, but of course your completely wrong here . 250 watts power at 8 ohms into an 8 ohms drive unit at active level is more than enough power. Using any more more power will actually destroy the drive unit to destruction. You don't know what you are talking about, and you're completely wrong about ATC's active drive power. As i said the new version has been upgraded and with more power supply capacitance. EXTRA power in active drive it does not need. It is only a 6 inch drive unit. 300 Watts class A/AB total power for a two way active speaker that can play upto 108 decibels at 1 metre . As reguards their active ASL 3 ways, it does not matter how expensive the amplification you use into their passive brethren to compare with their 350 watt or 850 watt active 3 ways, because their active versions, blow away any expensive amplification into their passive 3 ways . What you said does not hold water, fact, simple as that .

In the future when built in room correction becomes affordable passive wont make much sense. Companies still like SELLING passives because they are much more profitable.

Active speaker fans can be counted on to claim technical superiority. What does that mean? How is it measured? I can design an overly complex product packed with bleeding edge technology that will fail in short order and then function as a nice door stop. The more functionality included in a single package always means many compromises have to be made. If you want minimal or zero compromises the cost goes up exponentially. Interesting that the low frequency driver had no shield to contain the magnetic field of that huge magnet. A claimed to be 20 year old speaker is no excuse. Maxwell's equations have been around quite a bit longer.
