Hey all,
I recently picked up a pair of cheap Eminence 12" off of ebay and I'm trying to make something work with them. Amp is PE 250 watt plate amp and the driver specs are as follows.
*Power handling: 200 watts RMS
*VCdia: 2"
*L1k: 3.75 mH
*Impedance: 8 ohms
*Re: 5.20 ohms
*Frequency range: 27-700 Hz
*Fs: 27 Hz
*SPL: 93 dB 2.83V/1m
*Vas: 5.50 cu. ft.
*Qms: 12.75
*Qes: .34
*Qts: .33
*Xmax: 5.5 mm - this scares me, but why not try.

The subs will be used probably 60% hometheater 40% music.
After some WinISD time I've found that a clamshell isobaric 2.75 cu ft tuned to 25hz gives me good results, but I've never tried anything isobaric before. It leaves me 3db down at 28hz which is fine with me. The room is quite small at 16' x 12'.
These subs model terribly with any sealed enclosure and a ported enclosure isn't much better. Is there a way to model two separate small sealed enclosures in WinISD?
Can anybody find an enclosure that works better than what I have come up with? I would like to keep the box under 3 cu ft. Worst comes to worst I can resell them on ebay and just go for the Dayton 12" Quattro PR sub I was thinking of.
Thanks for your help, and sorry for the long post.
Andrew
