Thanks for the info guys. I'm not a big fan of subs for stereo setups, altho some speakers just need them (mostly electrostatic types) I'll just play with the placement, since there are back firing ports. I'll start off with them 6" off the back wall (which is probably too close) then walk them out.

I didn't "think" they should need a sub, but thought i should ask. I'm not familiar with speakers that have back firing ports, which i "assume' will effect the bass, depending on placement.
