Hey Mark--You got me worried here buddy--I have a room 18 X 18.5 and I was going to buy Epic60--2-M60ts, 4-QS8s,VP150 and a 350 subwoofer (my wife hates bass) but what if I have the same problem --not enough bass? How common is this? Due to the room I have to put the 60"LCD in the corner with the M60ts on either side. Axiom people said I could put the 350 subwoofer anywhere. Are other people having the same problem with the 350's?? Your thoughts? Should I get the 500?
