John,

The subs are Atlantic Technology T70PBMs. They have high and low level ins and outs, and these specs:

Type/Features: Sealed Acoustic-Suspension Enclosure, Powered Subwoofer
Driver: 10" long-throw woofer, 2", 4 layer vented aluminum voice coil, vented motor system
Typical In-room Response: 25Hz - 125Hz ± 3dB
Amplifier Power: 125WRMS discrete linear Class A/B power amplifier
Amplifier Distortion: <0.025%
Low Pass: Variable 60-125Hz, 12dB/octave low pass output
Peak SPL: 102dB
Magnetic Shielding: Yes
Dimensions (W x H x D): 11.375 x 16.5 x 14.9in
Weight: 37.5lbs.
Power requirements: 110V AC 50/60Hz; 240 AC 50/60Hz

The receiver has 80/100/120 crossover settings.

What I'm trying to get here is some reinforcement of the M22ti low end for music -- preferably in stereo -- and introduce LFE to my home theater.

Thanks for your help.
