Bacardi,
For overall balance in the room, I would encourage twin SB13 Ultras over one PB13 Ultra. Of course one PB Ultra will go deeper(16Hz) with plenty of authority, but two SB Ultras, if set up properly, will sound better with music and still provide plenty of ooomph in the sub 20Hz region. I added an SVS SB13 Plus(95% same as Ultra) to my existing Revel B15 and Klipsch RSW-10d, and my system is finally where I want it to be with HT and music.
I would suggest you run your SVS AS-EQ1 calibration before you lay out any more $$$, and see where it takes your system. I owned my NAD T175HD pre/pro more than nine months before I ever used it's Audyssey MultEQ XT calibration. Only after I bought the SVS SB13 Plus did I do so. What a huge improvement over manual setup.
