There is so much incorrect information here it's hard to know where to suggest to gather all the info. Few points. (1) "BL is so low" If it was higher, it would have higher SPL and less bass. A larger driver will need a bigger box. The driver is clearly designed as a woofer capable of getting low and you can't get that in a small box with high sensitivity. (2) Where is anyone stating this is a XBL^2 motor!? It is a MAGG which means it has effectively 2 top plates with a air gap between. The magnets used on the top are chosen to try and keep BL consistent through travel, reducing distortion and is a patented method. XBL^2 is also patented and very different. (3) You mention better drivers like Dynavox and suggest no actual comparison? (4)Don't under how it can be lower than FS - Big misconception that they cannot. In a vented or PR setup, the port or PR can be tuned below Fs to help extend the lower end (4) You call it a mid-bass and not a woofer as it only goes down to 40Hz. Well it can go lower and mid-bass frequencies are typically seen as the 200

BL seems fine given the Mms of 26.6g. Tradeoff of efficiency for xmax was made so I don't see this as a problem.

@Clobercow1

Yeah. That's a common tradeoff. Power isn't hard to get so efficiency isn't a big deal. Not to mention the use case for this woofer would be a small two way setup, probably for a desktop or a small room, so MAYBE the average user is pumping 10 watts into it. Labeling it as "It's shit" is just cringe... If whoever this guy is, wants to use PA woofers in everything, fine. Calling less sensitive drivers shit is just being obnoxious.

@@RobotUnderground That's a 8" driver. Why are you comparing that to the 5.25" Epique driver? Seems it's fairer to compare it to other 5.25" drivers. For example, the Tang Band W5-1138SM, which has a lower BL, higher Fs, lower Xmax and an even lower sensitivity. The "problem" I see with this driver is that it's difficult to make good use of all that Xmax, unless opt for some sort of actively-eq'd sealed alignment. Vented looks nice on paper, but then you eventually find out that you can't get a decently-sized vent into the gnat-sized box that the sims call for, and even PR alignments are problematic (try finding PRs with enough excursion that can work in such a gnat-sized box, LOL). I can see these in small "monitor" boxes though, with active EQ, or perhaps with one of the coils driven by a separate amplifier, to pull up the low end. II

@@Grommet2007 I think 8's are dumb. How dumb do you think, that I think a 5" "woofer" is??

5:12 You lost me on this point my guy. FS is just the highest point on a bell curve; it goes back down after. FS is the point where the mechanical suspension has the least control over the motor, but it never has zero control. I think the idea used here is in respect to ported enclosure design, where a subsonic filter is recommended around the tuning frequency to prevent damaging the driver (because near this point the suspension is not helping keep the coil in the magnetic gap). This idea itself assumes a driver plays below it's FS just fine. 7:54 Driver terminology is a combination of frequency response and system design. Midbass is 80-250+, Bass is 80-40, and Sub Bass is below 40. If I design my system like that, this driver can absolutely cover Bass and Midbass just fine. You may need more than one driver per channel to get the SPL you're looking for, but the cone moves at those frequencies just fine.

I’ve modeled this in WINISD and I can get crazy low tuning with great power handling. The 7” one gets audible output down to 25hz and maxes out at 106db which is more than adequate for smaller to medium sized rooms. This thing is no slouch.

BL is a product of two numerical quantities, field strength (B, tesla) and conductor length immersed in the field (L, meters) - the smaller magnets you have here are more common in small drivers for hi-fi and OEM car audio, and a smaller magnet makes less 'B', and then you have a certain number of turns of wire of a certain size that you can fit in the gap, and if the amount of turns can't increase to compensate for the loss of B then the BL product will be lower. BL of 9 isn't super high but it is never going to be as high as the BL products of large autosound subwoofers. The Dayton Audio Epique MMAG midwoofers are using "MMAG", a patent owned by Patrick Turnmire of Redrock Acoustics, which differs from XBL because it adds another layer of magnetic material between the first and second gaps to balance the flux in each gap. These drivers do have a short coil but they are not an "underhung" design because there is a B 'notch' between the upper and lower gap; an underhung driver has a continuous B profile in the gap. These are "brothers" of XBL but they are not using the XBL patent, so no royalties to Dan; the royalties go to Pat. I'm not sure if Enrique Stiles is still associated with Redrock, but he was a co-inventor of MMAG with Patrick, and the two of them are some of the "big brains" in audio consulting.

So wait. If you have magnet and it has a bump plate on it then you stack magnets on top of the bump plate and then add another bump plate. Doesnt that in effect cancel out the first bump plate? I think it almost kills the the magnativity of the first plate. By the way mcm electronics always had cheaper prices just not as much selection.

@@RobotUnderground bro.. I was actually thinking like ... If one speaker is say , 95dB and we use two such speakers Then its 98dB but then.. the individual speaker would take 1w each ... That's a total of 2 watts from the amp isn't it ??? Or is it just 1 watt and we get 98dB/m ? 😐

FWIW I think this MAY have a niche in car audio when space is at such a premium that you can't possibly fit a subwoofer cabinet anywhere in the car so the only course of action is to replace the stock woofers with these. Of course I'm ASSUMING that the drivers aren't so tall that you can't even fit the drivers in the first place which means the ONE niche I could possibly think of for these drivers died on the spot. That being said our 1986 toyota camry need a 5.5 inch woofer replacement since the stock ones are ruptured. I assume madisound... Or dynavox? probably have some nice budget drivers of that size.

i cant say either, but have you personally had this driver in your hands and built with it? I dont trust their measurements, or any company really. the ultimax is the worst subwoofer i ever tested but that does not mean this one is bad. not chosing a side but before you say bad things, it is more credible to just get it and test it then rant. just saying!

That's very low too, however power handling is like 6x so you can still achieve your goal with more power which is cheap. Not so much on the Epique.

If you not going to give it the 200w rms then what is the point in even buying something at 200w rms buy something around 50w rms instead. Under powering can also hurt a woofer that's why most people give it rated power or over.

XBL was designed by Adire audio back in the early 2000's. You don't know how drivers are designed and you don't understand physics. There are trade offs. Name a 5.5" driver that can be tuned as low with higher BL and higher SPL.

I was intrigued when I watched the video, thought it was a neat driver, but then again I don't know the pros and cons of it. Good to know. Have you ever heard of Silver Flutes? Ive had a pair of the 6.5 versions in the front doors of my caravan for not quite a year. I replaced 6.5 pro mids I thought were decent but the flutes were wayyyy better. They have a wool composite cone, it looks nice at the very least. They have a cast frame and a Decent sized motor. I only have just those on 75x2 amp in a 3 way setup But I paid $35 each I think at madisound so not bad for decent speaker.

Meh. I fully understand what you're saying but none of your cons listed kill the existence of this driver imo. As you well know, every driver is a compromise. Just because you dont agree with the compromises made doesnt mean that it literally shouldn't exist. Most importantly, my largest rebuttal is that watts are cheap as hell these days. Your first and main criticism was the BL and low sensitivity. I doubt anyone (knowledgeable) is using these in an application where a 5 watt tube amp is employed. Everyone's use case is different. Please don't misunderstand me your points are absolutely valid, just like the existence of the driver is valid for someone's individual use case. I've taken a look at the suggested "replacements" and some take a bit of a left turn if considering some specific uses for the driver. Finally (per a couple of your comments), no, more often than not transducers cannot replace an actual driver without noticing a difference in sound, assuming its in a balanced and somewhat linear sounding system. (Im assuming we're still assuming that the listener has the same listening abilities as you and I, otherwise your argument may actually be valid in the case of the average bass-head teenager)

I see more of a problem with the current flowing at Fb and the low efficiency , in combination with a relative short coil , lots of power compression ..... and which port can handle the volumetric displacement requirement? So you need a large passive radiator of good quality , or two smaller ones (mutual pertubation problem) . But visually very attractive , price is too high! Btw - how long do these Santoprene surrounds lasting? I assume no one can repair this driver because there is no replacement surround to get anywhere . ALMA association tried several times to standardize surround sizes but no luck . It seems the manufactures do not want the repair option for their customers , they are the masters , we are their consumer slaves , welcome to planet HELL! Makes me sick how we are treated here , really .... fuck it!

These things are built very thin (today). Under high loads you can hear air blowing through the carbon fiber weave. I recently bought a few of these and the passive variants, they all behave this way. Compared to the SB Acoustics cf woofer line, it's night/day quality. The SB cf is thicker and has a felt layer on the backside to reduce unwanted breakup/resonance associated with cf. Performance tho, is pretty silly for a driver this size. I built a SIX liter sub with a single 5.5" and dual passives. In-room response is strong down to 24hz. It's hilarious for it's size Lol. The passives all have different resonances tho, I had to fine tune weights on each to get them to match. I think there's a manufacturing consistency challenge with this product line...
