I'm looking again at the curves Ian posted. They're a real piece of work. Declining 3dB/decade from 100Hz to 20KHz.

Besides this, I still can't get over the fact that each active LFR will be capable of somewhere between 124dB and 130dB dynamically at 3 feet. The ADA-1500 should easily be able to deliver the requisite 4800W. The 1500 I have is peaking out at 2800W on my M100s and those of course have an analog crossover which presents more load. As I've said before, that 2800W I'm measuring may not be a true peak due to my meter.
