2nd, make sure the Qts of the driver is .28-.45 and that the Fs is less than about 30hz. Good excursion is also neccisary, so 8-10mm is just about the minimum. Likewise, those excursion numbers are one-way, so if the manufacturer lists the Xmax as "peak to peak", double the numbers I listed above.

I have an automotive sub (MTX 7000 series 12") that mostly fits the bill, except for the Qts. What effect will a higher Qts have on a home theater subwoofer? I'm planning a sealed box. Here's the T/S params:
Fs 26.4 Hz
Vas 3.18 Ft^3 (90.1 l)
Qts .55
Qes .59
Qms 9.20
Re 3.61 §Ù
(One Way) Xmax .50¡± (12.7 mm)
D 10.125¡± (.2572 m)
RMS 400 Watts
Total 1000 Watts
Sensitivity 1W/1m SPLo 86.8 dB
Thanks,
