One SVS PB13Ultra or two SB13 Ultras?

I'm currently running the SVS AS-EQ-1 with a pair of HSU ULS-15 sealed subs. Prior to installing the ULS's, I had a pair of SVS SB-12s (the predecessor to the SB13). The SB-12 were excellent and blended very well with my mains, but I needed a little more headroom in my open floor plan home. In retrospect the SB12s offered tighter bass, but less impact than the ULS-15s. I kind of wish I still had them.

Of course it's not possible to make an accurate prediction, but I would bet a pair of the SB13s would likely improve on sound quality over your single PB13.

Hope this helps.

Food for thought: there is no substitute for a great sub. I have a Revel B15 that is a 15" sealed sub and its in a room that is 30x24 give or take. So it is a very large and open room.

Sub EQ is really amazing especially if your placement options are limited. Why not try adding EQ to your current sub? You state that you may add that anyway so that's a cost you will incur regardless. I think that will give you an idea of whether or not to upgrade to two subs or if the one sub with EQ solves your issue. Remember that the best bass setup is actually four subs in the middle of all walls. That gives the best and smoothest response. Since most of us can't do that EQ is the next best thing.

There's nothing like a good quality sub. It's foundational to any system you want to build.

Thanks to all, Internetmin, I am trying to get my hands on a SvS As-EQ1 either way. If I like what it does to mine, I might keep it. I still like the idea of one in front and one in the back behind my sectional. The footprints are almost half the size of my PB13Ultra.
