John,
Thanks, I dug out my manual and you're right. All I have the option to do is select speaker size, level, distance, and height. Nowhere does it mention what the crossover frequencies are. Do I understand it correctly that if it crosses at say, 150Hz, and the Axiom QS4's response goes down to 100Hz, that there would be a hole between those frequencies? If so, how big a deal is that? I realize my receiver is very limited, but it was the only way I could convince my wife to get a DVD player and have something to drive 5.1. I only paid $150 and it's a Sony ES with digital amplification, which I thought was a really good deal. But as in most cases you do get what you pay for.
Thanks,
Tom
