I am running an active cross three way stereo triamplified (six channel) system.
My bass cabinets are vented EBS3, each carrying one EVX-180B driven by one channel of a QSC PLX3102. These cabinets are nicely flat to 32 Hz, and do extend lower than that to some extent. I have disabled the 32 Hz "subsonic" filter on the QSC, and instead implemented a 48 dB/octave L-R active slope at 20 Hz to roll off the subsonics and prevent driver overexcursion - the natural roll-off of the driver is somewhat higher than this. So configured, I'm pretty happy with the way these cabinets sound for music and movies, however I am definitely missing something on the extreme low end, and I was hoping to augment this infrasonic-to-low-sonic range with an additional sub.
Ideally, I would like something that can keep up with my mains (which are well into 130+ dB), but which cover the bottom octaves only, crossed at 32 Hz on the upper end, and extending down to 16 Hz at minimum, and 8 Hz if at all feasible. The project will be DIY, and difficulty is not really an issue. My budget is not set in stone, but I am thinking about $1K for amplification and $800 - $1K for drivers/enclosure, maximum. Huge transmission lines are probably out because I only have 8' ceilings.
Suggestions?
