Pre ordered a pb2-ultra last week when the deal came up and am wondering if I should change my order. I have been set on getting the pb2+ for a while now and when the ultra deal came up i jumped on it. I know it is overkill for my room, but It is the sub I want. My only concern is it wont live up to its potential in my 12 x 17 x 7.5 full-enclosed room. Does this sub need to be at a certain volume to sound good, or will the sound quality be just as good in my room even though I am not using as much of the juice as someone in a bigger room? I listen at or near reference levels most of the time. Eric at svs assured me I would be ok, but just want some opinions from some svs users out there. Will I be good with this purchase or not?
