I'm calibrating my two subs, and using my htpc to play back test tones. My receiver is on direct mode. When I play, for example, a 50htz test tone, my subs play it back, but so do my fronts. Receiver is set to crossover at 80htz and all speakers are set to small. Any ideas what's happening?

Crossover isn't a sudden changeover, it's gradual, so you should get some lower signals in the mains, just not at the same volume. Google 80 hz crossover images. Turn off/disconnect all but the subs if it bothers you.
