Hi everyone havent been on in awile I ended up getting an SVS sub (cylinder sub). The EP 500 just wasnt right for my room but it is a very nice sub. Axiom is great to deal with and I had no problem in sending it back. I demoed a bunch of subs at my house and liked the sound of the SVS the best. I am sure you guys are familiar with SVS. But I am happy wwith the rest of my axiom speakers M22s, vp150, QS8s.
