Gooddoc, I had a servo 15 before I bought my SVS PB 13Ultra. It was very musical but I noticed I had to have the subs volume almost full for music to hear bass. Then when I got my SVS I definitely got what I was missing. Great sub though. Anyways, I was reading up on the Signature inwalls and they look amazing as opposed to the onwalls(w series). They even have an inwall box that is sold seperately for $400. There is a review on Hometheatereview.com. If I had that money I would get those and a Sub 1 and a Sub 2.
