Thanks JohnK: When you say to cross-over at 80hz..I don't have a choice on this receiver!All it does when you you select THX-"NO", I think it changes the x-over to, I don't know what, as I don't know what the x-over is set at.The default doesn't say anything for this.Also, what should my x-over be set at, obviously I set x-over on sub to "enable".I tried the test tone in the receiver and I doesn't play the sub's tone!(???).I don't get it!!! Anyway, Thanks, Huck
