In about less than two month I'll buy my system and I think I will go with 2xM60s, 1xVP150, 4xQS8but I am still debating about which sub to get!
I can afford something in the range of the EP350 and I was thinking of getting it or the SVS PB12-ISD. Do you have any advice or other similar model that I should consider?

This system will be used mostly for movies and will be located in a dedicated HT room (12'x20'x8').

Thanks for the help!
