H/K 525...I have my M50s set to Large with sub for music, and small with a 60 hz cross to the sub for TiVo/movies. I've got QS4s for surrounds, so I set those and the nonexistant center (well, the TV speakers) to cross at 100 Hz. The funny thing with the H/K is that you have to set a subwoofer crossover, too, if you set the bass manager to independant (by input). I had mine set to 60 Hz, from when I just had the 50s. I realized that when I was recalibrating today, and I set it up to 100. Dialog's significantly better now. I think the way it's set up is the sub's crossover setting on the receiver is the maximum cutoff for the sub, so sounds below 60 from the fronts get sent over, and sounds below 100 for the center/surround get sent over. It's very confusing, and not well documented at all.
