nice system. and it sounds great... if you have more room... yeah I think you should get a different set up.. bigger speakers sound much better...
for instance i have:
polk rti100 ($530 each) speakers for my fronts
polk csi40 (399.99) for my center
and polk rti70 for my rear (399.99 a piece)
and a polk psw450 for a sub (499)
i also have a onkyo txds797 for my receiver...
that system sounds phenom. all put together with monster cable. it's the only way to go...
if you wanna know the diff between all sound formats, talk to me on AIM crashAG or email
gametavern@hotmail.com and i'll help you out. i know all !!!!
