An OEM we did some design work for in Denmark is quite pleased with one of the 8" Wavecor woofers used as a bass helper. Like the SDX7 fits into a petit box.

Andy, I see the reviews are on Wavecor's site. Dave, good to hear they're getting a good rep; I think the Alu shorting ring helps. I'll probably bite the bullet soon & build a 2 way computer monitor using Seas 27tbfc tweeters I've already got. Very tempted to go 2.5 way though....
Bass helper? Planet10, that sounds like something a multi-way speaker user would say! 😉 Those Wavecor drivers look pretty nice at first glance, I'll have to play around on their website further.
I already have a Peerless DX25 Tweeter , working very nicely in a JBL L77 Enclosure , using 2 very ordinary 10" drivers MTM .(2 x 10" Speaker Holes already there)
Will choose between 2 x Peerless HDS (832873 or 830875 or 830869) .
Already have tried 832873's , but want a dash more Bass , or see below .
or
2 x SB Acoustics SB17NRXC35-8
.
Several Commercial Speaker Boxes use Side Mounted 12" Subs with own PlateAmps , which I hope to eventually do .

It has a bit of a 'warm' character to it- could be the 'wool', heh! 😀
The FR curve has some inherent BBC dip unless you can xover fairly low.
It's easy to use, and gets great low end. 20ltrs vented = 40 Hz.

I love the M series from HiVi...
I've used all but the M6 and M12, but will be soon using the M6a. If it's anything like the other drivers in the series, it will have an amazingly good bass performance in a smallish vented box, and will take a lot of power while remaining linear and smooth sounding. Of course, you have to tame the FR peaks to make them listenable, but once done- you'll like 'em!
I have yet to find an entire series of midbasses other than the M's that have smooth extended bass performance, and a very clear vocal and midrange presentation. What more can I say?

Whatb about Beyma or 18sound?
I agree without knowing exactly what drivers this driver is going to be mated to every ansawer will be a bit off. If you example the 6.5" was mated to a woofer excursion and low requency response is less important.
8"? As far as I know Wavecor only has 7" and 10" (and a 12").
Wavecor's Balanced drive 7" woofers look good. A local manufacturer (Eastern Electronics) has been using Wavecor for a few years now. They have still to produce a commercial product using teh Balanced drive drivers though.
Thanks for those tests Andy; the distortion profile for 3rd harmonic is a bit worse than Zaphs test of the Peerless 830883 between 200-500Hz & the peak at ~1.5K, and probably a bit higher overall distortion below ~100Hz.
Can any German reader give us a summary of the conclusions of that test?

D'oh, just realised Andy's test relates to a 7" unit; I was thinking of the 6" WF106WA02 which is available here. Interesting that Wavecor give before & after burn-in figures for the 7" unit, and the test results are consistent with a slightly burned in unit - looks like Wavecor's published measurements are reasonably reliable...
Well, I wrote a huge response before reading carefully and then had to delete that mess. 🙂
Mid woofer as in a whopping huge midrange with a big live classy sound? That's a Tang Band W6.
Its pretty efficient so you'd have to pad it down if you're still planning on using a single 10" woofer with it. Perhaps the Dayton RS 10" woofer can come close? Dayton RS270S-8 10" Reference Shielded Woofer 8 Ohm | Parts-Express.com
You'd probably like an electrostatic tweeter (clear) to match up with the tonality of the woofer (clear) and midbass (clear). It would be a very rich audio experience.

I am very happy with the Peerless 830874 (6.5 in. PPB). I have it in 0.25ft^3 (7 L) closed. F3 is about 75 Hz but in my office setting, there is still usefull energy at 40 Hz (lowest E string on 4 string bass still sounds solid here). This Peerless has the smoothest and flattest FR of all their 6.5 in. and I'm crossing over at about 3500 Hz. I agree; I don't like crossovers in the 1K to 3K range because of the female singing voice and piano. (I don't care about wide dispersion from the tweeter). Hope this helps!

Here's another interesting one - nice frame, copper in the motor, $70 - though I don't know if it's available outside the US: Eclipse, W6520R-4
Last year a friend of mine asked me to knock up something "cheap-and-fast" for his workshop, so I made a 2/3 cuft. 2-way vented box with some Fountek FW168 and Vifa XT25 lying around for years. Now I am wondering how I ignored those this lomg, because they sound absolutely amazing: fast, punchy, excellent imaging and details.
You need to fiddle a bit with the resonance peaks of both the woofer and tweeter, but if you get it right it turns out that not many other combination can beat the price/quality ratio of this combination. Not a champion in the lowest octaves but whatever is there is clean and articulated.

For 45 dollars it is a steal...

If you had a different preference, there's approximately 2 alternatives.
1). That box is too big (for bass efficiency).
2). Use the woofers paralleled (for the "champion" you're looking for) along with an amp with paralleled outputs (to push the double load).
I'm just saying that one of those *may* be the case.
Also, perhaps a wider baffle or BSC circuit, or even a rather spendy subwoofer-sized BSC circuit (to prevent loss, it would be a big thick high-class inductor), to get that bass louder, is a possibility. That would be most practical with the paralleled woofers (half size inductors with 4 ohms, you know).
It looks like a nice driver--far too nice, which makes the crossover a challenge (there's no ditch to fill), since the potential crossover points are approximately 3khz for 2-way (shouldn't put a lot of power to shake up signals up to 3khz) Or with the paralleled woofers build, a 3-way with the midrange in the neighborhood of 250khz~300khz. If crossover point at baffle step, the box/baffle area is either quite skinny for 2-way or quite wide for 3-way (or bsc). Although quite a lot of effort for it, I'm sure it could be an awesome speaker. That driver appears to be compatible with a series or hybrid series crossover.

If you read my post carefully you can see that I was not aiming to create "a low end champion" just a half-decent 2-way for a workshop to play music while working in there. I think I have a pretty good idea how to create a good 2-way speaker with real low end (the Mani-2 and Forest might be good examples,but that was long ago......). I just wanted to point out that with some attention to the details and their specific problems those can be excellent candidates for such a project. Where I completely agree with you, is that in the hands of someone who knows what he (or she 🙂) is doing, these must be one of the best value for the price drivers available in their category.
