Thanks Alan and Jason,

Your input has been great, Im learning heaps about all aspects of home theater on this site and it has been fun slowly moving through the construction of my room step by step.

With the Denon 3808 there is 1 pre-out for the subwoofer , what would be the best type of cable to run to the Axiom 350 sub. I was trying to get a clearer upscaled picture of the back of the 350 to see what connections they have on there.
If I want to install a Buttkicker ( the kids want it for game play ) that also needs a pre-out from the receiver. They say it comes with a Y connector, will this impede or degrade the signal in any way by running two components from the same pre-out.
