Here are some specs if you like that kind of thing. I had the Servo-15 and the PB 12 Ultra / 2 in my house at the same time to decide what I would keep. Now, by my signature you may think the Servo won me over but that's not really the case. If it was up to me and I didnt mind the size of the SVS it would have won based on price. I couldnt tell much difference between the two; if anything the Servo may have sounded a little better for music and the SVS may have sounded a little better for movies. I was able to get the Servo at a comparable price to the SVS and I like the size better so I went with it. If I had to pay full price the SVS would win hands down.

I think I have one somewhere; let me see if I can find it.
Has anyone every come across a frequency response graph for the Servo 15 subwoofer? I found one for the SVS PB13 Ultra. Thanks.
