I need walls. Everything sounds great but I really have to crank movies up to really enjoy it. Music is dialed in for stereo and surround. I didn't have to change anything but the toe in. Used my line laser to see exactly where the sound was passing the MLP. Reduced toe in to point beyond the outside edges of the couch and I have great sound no matter where I'm sitting now. Running the speakers at 40hz right now and so far I'm really enjoying them.
