Does anyone have the specs / TS data for the 10" Peavey model 121 (8 ohm)woofers?
(I have posted on the Peavey forum, but no responses. I have searched their support areas, but no joy, and I can't find anything published elsewhere.)
Thankx

PS I have a pair of 121's and I'd like to make a pair of light duty subs if the drivers are suitable.

If you've got DSP, there's a lot you can do without T/S parameters.
If they were mine, I'd set out aiming for a 60Hz cutoff, build a cabinet that looks somewhere near the right size, add a 3" port tuned for 60Hz, and EQ the rest. Be careful of massive amounts of boost, but you ought to be able to get respectable performance there.
Alternaitely, its easy enough to measure the impedance curve and derive from there.

121-8

If you have a 10-12W sub amp do a 120-150L sealed enclosure. Qtc = 0.85, F3 37 Hz in room.
A reflex is difficult to tune and might sound awkward (boomy) if not done properly (but accepts more power@Xmax ~50W. For the 4 ohm it's ok, but for the 8 ohm it doesn't work but if interested anyway to know: VB = 200.0 L, FB = 30 Hz. This if the specs are correct. I would measure it myself because it was meant maybe only for sealed?!

Oh dear, that's a big cab!
As I have two, could it be worth running isobaric, to halve the cab volume?

It works very nice (from printed spec data) as a sealed woofer in a multi-way system, not a sub. Maybe it was intended to be designed in this way, for that particular application, sorry...
Hi,
120L to 150L sealed is way too big for a 39L Vas driver.
70L sealed and well stuffed is about the upper limit.
rgds, sreten.

sreten,
You are right. A 0.95 Qtc doesn't make any difference, maybe a +/- 1dB in LF. Not suited for a sub, though, but maybe very enjoyable as a SET driver.

OK. Of course, but I didn't immediately see the connection. You're suggesting the 89dB sensitivity is high enough to consider using with a low-power amp?
hello! a bit late but i recently found the tsp. http://webcache.googleusercontent.c...s.xls+peavey+96000296+tsp&gbv=1&hl=de&ct=clnk have fun. http://files.diyaudio.com/forums/images/icons/icon10.gif
