I will be hooking up the unit between the receiver and the amp. I have a Yamaha 795a receiver. The bass management is only large or small, and bass to sub, main, or both. The distance from the front to the listening position and the rears(I have them on my back wall) to the listening position are the same so the dely should not have much affect.

I think I will try what billdean said. I just a little concerned with the bass from the center going to the sub. The crossover of 100hz is a little high.
