Thanks John. That explained a lot. My Sony receiver, that will soon be replaced by a Onkyo 875 as soon as it arrives, has only 60, 90, 120, and 150 crossover settings. Right now I have all set to 90, but previously I had it set to 60 for mains and 90 for the rest. With music, all 2 channel, I prefered the 60, but I listen to movies the most and so I didn't want to lose the LFE and I set it to 90 for everything. I didn't find any difference in quality for movies, mostly because I don't really listen for that during movies, and the music is not as repeatable like with a nice bass guitar while listening to music. I'll try 60 again. With the Onkyo, I'm thinking 50 will be a good crossover point for my m60s and 100 for the vp100 and qs8.
