Rick, I will point out one thing to change with what you are doing. Your receiver has a crossover (low pass filter, set at 80Hz?) on the sub output. You also are using the crossover on the sub, set to 70Hz, if I read you right. You should never use both crossovers, as this is what is referred to as cascading crossovers, and can cause all sorts of problems. In this situation, the crossover on the sub should always be bypassed, or if it has no bypass, it should be set to its highest setting, to avoid the two crossovers "running" into each other.

Also, if the mains are set to "large" they don't ever roll off. Any speaker set to "large" bypasses any crossover frequency you have set. Look at the second article MikeNg linked to.

They flutter behind you, your possible pasts. Some bright-eyed and crazy, some frightened and lost. Last edited by JohnRice : 04-12-2007 at 05:20 AM.
