fEarful 12 Subs. A Peavey IPR-3000 DSP can serve as active crossover, parametric EQ and power amp -- 280 W available for each line array and 400 W available for each sub. Crossover frequency can be in the 125 - 150 Hz range.

SPL for 18 drivers ≈ 77.5 + 10 log (18) ≈ 77.5 + 12.5 ≈ 90.0 dB. With 500 Watts input this equates to 117 dB.

SPL for each bass cabinet ≈ 90 dB. With 400 Watts input this equates to 116 dB. Two cabinets side by side with 800 watts total input would be capable of 122 dB maximum output.

Thoughts, suggestions and comments will be welcomed. Thanks!
