I've been using the ICBM for over a month now with my B&W 602 S2's and a HSU 1220HO sub. I could not get them to blend well together with the fixed 80hz crossover from my processor--now they sound great with the crossover set at 60hz. Nice build quality, my only quibble is the turn-on transient which I avoid by leaving it on. Well done, Outlaws.
