would a high efficiecy woofer (say an eminence beta 12) in a compact (say 2 cu. ft) box below the line work to get a clean 40 - 50 Hz for domestic applications?I'm pondering the same question myself.
I was also wondering if a sub amp (they usually have 12dB crossovers) tapped into the speaker level input to the line array might work to roll off the bass around 120 - 150 Hz ?
Thanks
