hello everyone, this is my first post . a few questions. i should be receiving my new svs tomorrow and have purchased the new matrix, the haunting and gladiator for the ocassion. my listening room is approx. 17 x 26 and i often listen at/or near reference. should i follow any break in procedures prior to listening at above material at reference?? plus im thinking of plugging one port, w/ XO set at 20HZ, do you think i can safely obtain reference in that configuration in my size room. btw, i did read edward's review of the pb2+, which was one of the factors which led me in purchasing it. thanks everyone in advance.
