Qts is less than that used in the SXD and a larger Xmax, Fs lower... so I thought it would be ok. For about $10 each with the summer sale, seemed like a good candidate...
Yeah, would love to use the RS225 but if I go with 5 pairs, that's 20 drivers, or nearly $2000. 20 of the CES driver would be $200...

I didn't know you wanted 5 pairs. Then, I suggest you buy a few extras... just to future-proof your design a bit. 🙂
I'd still go with a proven design that would future proof my builds. I really like SBA. They make great drivers. Like this one, that is very reasonably priced:

This would be a good choice Perceval. Bought 16 pcs to test. Prelim test on 1 woofer, sound very clear which is good news for me.
Brand is ACR big name in Indo for Pro Audio. Dirt cheap & incase your wondering they are the manufacturer behind SB Acoustics.
Hopefully you guys can find a source of supply at your end to test.
Cheers

Cool!
I'm not too far being in Taiwan. 🙂
Their FR looks a lot like most SBA FR too. Makes sense that they are the same manufacture.
There was a rumor that the good stuff from Dayton was coming from Usher in Taiwan. I called them multiple times, but they never acknowledged it. Too bad. I would've loved to pick some drivers right off the assembly line! 🙂

You asking about the ACR woofers ? They look like foam but feels rubbery unlike foam surrounds. From info woofer cone is waterpoof so I assume
that the surrounds could be a hybrid foam rubber type, that is if there's such a material. lol Anyway thery're so so cheap buying more to keep as spare
won't even hurt the pocket, $9 a pc including shipping to me
Here's what I am settling on as a compromise between the expensive RS225 and the super budget GRS poly cone:

Has anyone here played around with SLOB subwoofers? Tomorrow a kind DIYer is gifting me 4 SD270A-88's, and I was thinking they would be perfect for SLOB subs. I know there are ripole subwoofers, which are similar. As far as I can tell the only thing that keeps X's SLOB's from being ripoles is that the back waves aren't slot loaded as well? Maybe I'm misunderstanding the concept of ripoles
I'd start off just making one with the 4 I'm getting for free, but if it works out the idea would be to make another, and use them as bases for a modular full range speaker pair (DSP, at least for the subs)

Look for smooth bandwidth up through 1kHz, good sensitivity, decent Xmax, as low Fs as possible, 6.5in to 8in and low price to make it economical since you need 16 of them.
Hello.
Long-time lurker into this thread, now looking to build a version of these but with a 8PE21 midrange and TPL-150 as tweeter. The 8PE21 in a 12" baffle starts dropping abruptly at 280Hz and know of a user crossing it at 250Hz with a 16" baffle.
I believe I could use either 8x 6.5" woofers like XSD for a xo up to 420Hz or 6x 8" woofers for a xo around 350Hz. It seems 350Hz would fit the 8PE21, so I´m wondering about pros/cons of going with 6.5" vs 8" woofers.
Using GRS Poly Cone Rubber line as examples, comparing frequency responses of 6PR-8 vs GRS 8PR-8, the former starts dropping at 80Hz while the latter does so around 60Hz. I have sealed subs to use below the SLOB yet I guess reaching lower is generally better. 16x 6PR-8 would cost $215 vs $180 for 12x 8PR-8, so price-wise is a tie.
Are there benefits to the 6.5" that I´m not realizing or should I just go with 8 inchers?

I haven't gotten to it yet- been busy with rebuilding a set of Acoustats, dealing with family health issues overseas, etc. Hope to later this summer/fall....
@cab
Sorry to read about the family health issues overseas. I can relate to those.
Did you get the drivers? I´m curious about their build, especially the basket that seems to be stamped steel that make me wonder about resonances, much like I wonder about the GRS 8PR but DS215 are $54 each vs $15 for each 8PR.
