Just finished my attic infinite baffle subwoofer. Two 15 inch drivers in a manifold powered by my harmon-kardon citation 16 amp. The drivers are Eminence built especially for IB use for Hawthorne Audio. After some time spent listening to different room locations with a box sub at the listening seat, I determined the best bass was coming from a spot almost above the left speaker next to an inner wall. XO is around 40 Hz with a passive line level crossover I built, using the preamp of an old TOA mono amp I had. The response is very good down to 25 Hz, down about 8 dB at 20 Hz. I'm very happy with the bass quality. Very natural. I have some pics in this gallery>
