registered as weapons in Boston :) Very cool amp. Your LR will rock! I tried cranking a 60 wpc sand amp with my 4 Pi Pro's rated 100 dB sense...gave up trying to light the distortion indicators (1% thd) when Stevie Ray Vaughan was cruising at 110 dB...about 10 to 15 watts input at most...standing between the speakers was a very "moving" experience...the sound was massaging my internal organs..."isometric audio tai chi"...ear muffs as always! Wayne, how exactly do you crank those crown 1200 amps up...are you and the amp in one room, and the speaker is next door? Sam
