I have just started to run my YPAO since my SVS PB1 sub came today. The thing is, when it's running and does the test tones for the sub, you can barely hear the sub. I'm not deaf either, I really mean you can barely hear. I didn't even think the mic was gonna pick it up. My sub is about 11 feet away and it chose 14 feet. Seemed kinda weird since every other speaker was on the money. Anyway, I let it finish and started with "The Matrix." I played the lobby scene and it just didn't sound right. It seems like it's missing a huge part of the sub band. So, I threw in DVE to do some sweeps. I did a Dolby test signal for LFE and I could barely hear anything. I've gotta have the volume up around 0. I plug my CD player directly into the sub and I couldn't put it past 1/3. I have a really small room, 12 x 16, and after hearing what these subs can do, and plugging it into the CD, I don't think I should have it close to 3/4 when I'm listening to a movie or music or something. I've got my new Axioms in the back, old Infinities and an Atlantic Tech center that are being replaced with Axiom. I can't see how these three old speakers can outpace this sub. I guess the main thing I want to know is with the YPAO test tones. I have the sub on 1/2 gain and I can barely hear the tone when it moves to the sub. I am gonna try and hook up an old receiver, but that's gonna take a while. Would your take on this.
