Thanks for the reply!
Using DVE to test frequency response (should have thought of that before), I can begin to feel/hear at a few ticks under 24hz, which I guess makes it good enough for home theater use. Also, thanks to a photo online, found out it has a 12" woofer, so I think I've pieced together enough info on it.
Two other questions:
The subwoofer has a crossover dial (70hz, 100hz, and 150 hz) and a Level dial (0-10). From what I understand, it's best to have the subwoofer crossover set as high as possible, and have the receiver handle that aspect so as not to have it interfere, correct?
My receiver doesn't have Audyssey, so I'm using a Radioshack meter to calibrate audio levels. Everything sounds right, but I've had to set my subwoofer's level to 1, and reduce the subwoofer -12db through the receiver. When I get home tonight, I'll try to calibrate from the 0 level, but my question is what does the level control do? I'm assuming its amplifying the signal, so I guess calibrating from 0 would be best?
