@@pradiptawork No offence, SBacoustics are highly appeciated among speaker builders in Indo. However, the manufacturer, Sinar Baja Electric (Surabaya city, manufacturer of ACR, Legacy, etc), hesitate to market them in Indo. Finally one of car audio player in Surabaya get the distributorship for some models (maybe only models more suitable for car audio applications only). In this guy threads, he even got scolded for not wearing a pair of shoes when visiting the factory office :) Still, getting SB acoustic drivers are not easy to get in Indo, you cannot get SB13pfc025 in Indo. And if you compare local price usually more expensive than partexpress/madisound/etc (perhaps, Indo distributor purchase volume is not comparable to those international distributors).

Eminence makes some good stuff. I'm looking around for my car audio upgrade project, and there is a lot of weird stuff out there today. --In any case, I never like the sound of the aluminum voice coils. --The last Dayton 8" I had made very nice sounding bass. Most people thought I had a 12" subwoofer. Suppose the sealed enclosure design helped. But, it didn't last very long. I kept trying to get more out of it because the older it got (couple months) the less sound it produced, until it one day simply stopped playing. ---

what size of port of the box? i was recommended 6L 50x195mm Fb 65Hz (flat until 76Hz, F-0.5dB, with a F-1dB of 70Hz) i was going to try 11L 50x140mm port and Fb 55Hz (82Hz to 165Hz F-1dB below flat), plays down to 55Hz F-1dB. as you suggest 14L and my guess Fb 50Hz 50x130mm port,( 65Hz to 196Hz F-1dB below flat). plays down to 50Hz F-1dB. it does come a bit lower then the 11L but it is not as flat. so it depends where you want that the volume of that extra 5Hz. but this is the base line that is so hard to find and after that you can play around with it. but i beg people please be redundant if you say it work in a box with FB 30Hz then please say what volume in Liters (unless you like 32" inch measurements i get it 1/8" is less then 10, but after that you might as well use mm) and vice versa. three simple things Volume of Box, Frequency of box and port tuning, and Size of port DxL. it would speed up the learning curve greatly. it is nice to run simulations but without other examples to base it off of it is hard to commit to a build and see what the range of personal preferences exist.

1:45 Due to it's high sensitivity, you could use a really large choke on it to mimic a sub sound and you can blend it with a smaller choke as well. The sensitivity goes down, but it will suit the lower sensitivity tweeters and that is a plus cos you would then have a wider range choice of tweeters.

The 6.5" version of the SB is just as great and has even deeper bass. Only downside, it needs a fairly big box, to go really low.

I'm planning a ported two-way with a larger 8" mid-woofer, and SB is definitely high on my list. Budget is around $1K for the pair, so I think I can fit some pretty nice parts in the budget. Need an 8" that has good bass, but can get smoothly up into the mids, and a tweeter that can crossover low. I'm thinking Baltic Birch for the cabinet with a nice veneer, and some high-quality crossover parts. I want a bit of a stunner SQ wise.

@ImpulseAudioSpeakers

ziggy8757 you know I really had to ask myself about the 180 because it is better for 2 ways. But I had more experience with the 225 and think it sounds better. Also the bass is a lot better in my opinion. It’s amazing what surface area does for bass. The 225 is a bass machine. Certainly you’re right though, the 180 is also a tremendous value and great choice.

I am really liking the paper version of the Dayton Audio woofer - RS225P-4A. The paper cone is a blend of 3 materials - paper, fiberglass and Kevlar. The 4 ohm version has an Mms of 25gm, and the 8 ohm is even lower at 23.6gm. They don't have the breakup mode nearly as much - the 8 ohm is slightly smoother.

Ground Zero GZIW 165X-II to 400Hz and i'm going to pair it with Visaton B80 as mid-high range 400-18000Hz. GZIW165 has pretty low fs=43Hz. B80 has icredible flat response, it's just magic thing they did on this fullrange speaker.

You are absolutely correct about the Dayton Audio RS225-4, this is a great 8 inch bass-mid driver for $50, with stiff aluminum cone, rubber surround, a low fs of 33 Hz, a very flat response up to 2 kHz, which makes it a great choice for a 8 inch two way system, and a large vented alignment of 1.5 cu ft, or 40 ltrs, for an f3 of 33 Hz, which is amazing for an 8 inch driver, the lowest you can expect to get. I have built similar systems and the bass, while not earth shattering, is quite pleasing.

That's the challenge of an 8 inch two way system, finding one that will extend into this range. I agree that may seem high, but you don't want to cross a tweeter less than one octave above the fs, so as to have it operate within its nominal impedance range, and to avoid driving them too hard and burning them out, and also to keep them from honking. I have built several such systems successfully, usually crossed at 2 kHz.

Best midwoofers - are those that are easy to work with and simple to filter. Usually these are speakers with a descending frequency response, without any emissions at the end of the frequency response (in the form of a “shepherd’s stand” or mountain like most SB, which require high-order filters and the use of notch chains).

The break up is easy to see in the measurements. You just have to cross low enough and they sound great. 1khz for the RS225 is reasonable. Could even do 1.5khz is using steep slopes. Probably need to go active to get the slopes steep enough.

Both driver have test videos and measurement files to help you design. As you’re just starting out that will be a big help for you. As for the woofer, that will really determine the size of box you can tolerate. For home theatre I would suggest something large like the magnum 12 or a pair of 8” woofers. You’ll want a lot of efficiency to give you an impactful sound. A pair of Dayton audio RS225-8 maybe... These are all under your budget I believe, but there’s no sense in using something expensive if it’s not necessary. I’ve suggested drivers I’ve actually tested on this channel because you’re starting out, so it will help you know how to use the drivers and how the measurements are. If you didn’t need that I may have other suggestions like SB Acoustic woofers or pro audio woofers.

I have a question regarding the home theater speakers starting @ 2:02. I have also been considering a design using two midranges to keep up with 2 larger woofers. However, placing the midranges side to side reduces horizontal dispersion. That's ideal if resonate frequencies within a room are intended to be kept at a minimum for speech clarity, and left, center, and right speakers' mid ranges are kept at minimal interference with one another. All is good so far, but the low end woofers are then even more wide in terms of dispersion relative to the somewhat "nearfield" midrange arrangement. It's becoming a mess. Have you ever considered dispersion control of the larger woofers so the lower mids, ~300hz and a touch lower, are kept contained? Placing two midranges vertically has the draw back of limiting vertical dispersion. Imaging becomes a problem for listeners above or below the midranges. Now we're running into the problem where our hand is forced to complete a line array. That's a path I have no intent of going down. That and the narrower dispersion of the midrange is now completely done away with. Is the best solution using a larger midrange and then placing two large woofers side by side underneath? I'm trying to control dispersion across the mids and lower vocal region.

Anonymous DueToFascists all good points. Making horizontal mids work properly is quite a nightmare. It’s important to keep in mind that although the mids will limit dispersion horizontally, they’ll become less directional and more omnidirectional as frequencies drop. By the time the woofers come on the directivity of the mids is very wide. So they actually blend quite well. Designing directivity way down to less than 500hz gets extremely complicated and I generally allow the speaker to go wide dispersion. My primary concern is with the midrange reflections off the walls.

Ok, so it's your opinion that lower frequencies which go much wider than the mids do not really affect speech and vocal clarity. It's been my experience, possibly misinterpreted by me, that when bass overly fills a room it's begins to sound like uncontrolled mud which negatively interacts with the highs and mids. Frankly, I'm beginning to give up a bit on "high fidelity" tv and movies. They're mastered in such a way that doesn't work well with high fidelity left/right 3-way speakers intended for music. The bass comes on in overly exaggerated waves...even during speech. A good hi-fi 3-way reaches far too low for how movies and tv sound best in one's own home. I then see many people trying to make up for this dynamic by cranking up a center channel. It then sounds like a ball peen hammer on tin. For tv and movies, I like smaller left and right speakers that can't really handle the bass below ~90hz. I then augment with a sub-woofer for when a good wallop of sound is desired. One possible solution for me is to find a receiver or dsp which keeps decibel levels within a controlled range for a given set of frequencies. Or simply find hi-fi left and right speakers where the bass can be turned down during tv/movies. I'm starting to realize the frustration people are having has nothing to do with speaker driver quality, distortion, or even desired flatness. The second problem people think is causing their woes is dispersion control and room treatments. I guess I fall into that trap thinking that if only I could control dispersion speakers could sound good across all media platforms. It really has to do with music vs tv/movies mastering. People keep spending $10 grand plus on their left and right channels and then wonder why they're still unsatisfied because they don't enjoy everything (tv, movies, and music). I have a cheaper solution for most people, myself included. Spend ~$3 grand on a left/right combo for music and then use a $1,000 satellite/sub combo for tv and movies. It looks awful and appears one is lost, but I think it makes more sense.

Anonymous DueToFascists I think you’re probably struggling with a combination of the room and the mastering. I agree the music vs movie mastering is usually quite different and sometime difficult to make the two work. In the bass department that is. I’m not sure directivity is the answer though. It is an answer but probably not the easier or cheapest. Have you measured the response at the listening position? A mic and Room EQ Wizard can really help improve your sound. We the bass to give a gentle roll of towards the highs. Don’t EQ flat. I definitely believe in using subs. Even for music but definitely for HT. You can trim the bass a db or 2 as required depending on the mastering and your mood. This may help with what you’re facing.

Impulse Audio I agree. Your tips coincide with what I've observed throughout the years. I borrow the testing equipment from a friend. It's been awhile since I've tested and I avoid it because I know what's wrong with the room/house. Good music has always been easy for me for both listening and entertaining guests. And sometimes I use a sub with music, sometimes I don't. Regardless, the experience is ideal. But tv/movies/youtube are just a mess when I want to use a good pair of high fidelity left/right speakers which can respond near flat (+/- 2db) to ~60hz and below. It doesn't matter if I use a sub or not, or even if I use a center channel or not. I turn down the bass a bit and/or boost the mid and treble and this truly helps. Regardless though, the experience is not to my liking. Only when I use satellites/bookshelves and a sub during a movie is it to my liking instead of using my large left and right speakers I use for music. Music is typically within a reasonable sound level range and I assume that's why it's so forgiving in a less than ideal room. Whether I play it soft or loud, it blends quite nicely and vocal clarity is never lost. But with movies, the sound range difference is too large for my liking. And the bass effects are ridiculously loud while there is still speech present in a scene. Voices sound like unintelligible mud. Worst of all there is no consistency between voices and explosions/rumbles. Sometimes it appears they treat male voices as though the bass frequencies present are just low frequency information that should be boosted no differently than when a bomb goes off. At other times, they're sensible and they realize voices containing low frequencies shouldn't be treated like the fire bombing of Dresden. ;) Thanks for your help, I'll keep learning.

Theoretically I understand what that means, but never experienced that effect in practice, as I don't listed at high levels or have some gear, which I can afford to test that way or rather to understand what just happened. In other words: if there are 2 different speakers: one built with 4Ohm woofer, and another with the same woofer, but 8Ohm version and both with the same 4Ohm tweeter, then final 2 products with crossover will be ~4Ohm and ~8Ohm nominal with theoretically similar SPL and sound quality performance. When testing them with different lets say sub-200USD amplifiers, as 95% of all the music lovers have... What differences in music quality will be? SPL? What will be to the amps when played at normal levels? Party levels? Max levels with clipping? And so on. There are LOTS of info on this topic on internet but much of it is so misleading

I do admit though that the mids in that speaker are the real star of the show.

SB Acoustics make 4" coaxials (their smallest) and use that with the SB woofer and you would have a 3,000 speaker sound. Especially if you mucked around with the mounting of the drivers and made fancy boxes and a good crossover. Their coaxials are proper coaxial (point source time aligned) and combined with superior 4" medrange (with it's own bass) it would sound amazing.

I MADE THE BEST SPEAKERS I EVER HAD I just finished making a pair of home hacked (3" coaxial driver + woofer semi omni speakers) and they are the best speakers I have ever made. See short video link below for a clearer picture of what's in the next paragraph: The "tweeter" is a stripped down 1.5" micro FR driver (with no cone) and a very thin bamboo stick is super glued to the voice coil tube of the micro FR driver, and the stick pokes through a hole (drilled through another larger 3" FR driver) and the frame of the micro FR driver is hot glued to the back of the 3" FR driver (with the stick inserted into the hole). And a thin 1/4" foil "tizzer" is super glued to the other end of the stick that is just poking through the front of the hole in the 3" FR driver (just above the start of the 3" cone). It's a coaxial driver and it's "time aligned" for point source sound! And that's the only purpose of doing it like that. And to keep it time aligned I covered up any holes in the mico FR driver frame to stop any residual sound coming from the driver itself. I also run the 3" drivers slightly above the speaker enclosure hole, with a 4" polypipe tube going down into the box (to clear up med and also acts as a bass vent for the 3" coaxial driver) and the outside part of the 4" polypipe is also a mount for the 3" driver (in a slanted position). And I run it with an extra woofer below (also slanted). The 3" driver being ran above the hole helps clear up resonances (if it's done right that is) and boosts treble and sweetens the voice sound and some of the sound escapes through the gap and goes behind the box (and is less "muffly" from behind). But the size of the gap between the driver and the speaker box hole is incredibly critical! Move the 3" driver inwards by 1 mm and you get a "squarky" loud voice tone and move it 1mm out and you get a soft "husky" voice sound (with not enough "squark"). And "in between" is the best position for sound, but you have to have the gap within 1 mm up or down. lol And the gap is way larger on the top of the driver, than the bottom. It's angled above the hole to get a variation in resonances cos of the odd slanted geometry. The gap is just a bit more than 1/4" on the bottom of the driver and about 5/8th" gap on the top of the 3" driver. But that only for that particular enclosure, for any other enclosure it would be a different gap. Hard to do but you can move a driver up&down way quicker than changing the crossover. They are also semi omni style speaker boxes with the drivers angled at like 40 degrees, with inverted pyramids above the drivers that act as dispersing "horns" (see short video link below). The woofer has inductors set up for 3-way (cos it is) and all the signal is put through the 3" driver except the lower bass, which is handled by the extra woofer. Also the 3" driver is slightly resisted and it is "tizzed off" with a small value cap in par'l with the resistor. And the "super tweeter" in the center has a 1 mf cap (very important to have a cap on it cos otherwise you will have a dancing tizzer)! It's made from a micro FR driver, and moves without a small value cap on it. They are the best speakers I have ever had and I plan to sell the coaxial drivers by themselves) (and with a 1 mf ceramic cap on the "super tweeter"). I'm planning to make them from 3" to 5" diam (best med size). The med is sweet cos of the small driver and treble has way better transients at high frequencies cos the stick and tiny tizzer is way lighter than the 3" cone (and point source "headphones effect" to boot). Also you don't have to run them above the speaker box hole (I just do, cos it's my style). A one minute video: kzread.info/dash/bejne/h6B-qrSKmcfZpqw.html

No wavecor drivers ?

Gerrit Govaerts I haven’t used very many but they are good. A tad expensive maybe.

Can you implement these into car audio?

Absolutely. Not sure these would be my top picks for CA, but for the most part they would be great. Depends on the application really.
