Axiom Home Page Forums General Discussion Stereo EP400 or EP500 ?

I actually own a EP350 and i would like to upgrade. I have the chance to sell it for a good price so why not. I actually looking for the ep400 or the ep500. My room is 11x8x27 but listening seat is at 12feets. I know it's a huge room and at first look the ep500 would be a better product. But since i live in a twin then i can't push the sub to his limit. So maybe the ep400 would be more musical sub but who can give me some good bass for movies. Take note that i would eventually add a second subwoofer in a near futur. So 2xep400 or 2xep500 ?

Thanks for advice
