hi,
i used to run a pb13 ultra. i then sold it and went to 2 lesser quality matching separate subs. i could not get a smooth response with one sub. i needed one in front of my listening postition and one behind to get a smooth response.
i miss the pb13 ultra for lows. for HT that is what you want. a powerful sub that digs really deep.
going to two subs will help your frequency response if it needs flattening...provided you position them correctly. if your response is pretty flat with your pb13 ultra and your planning to get a sub eq, you might be fine with just that.
im not sure on the specs on the sb13's as i have not kept up with svs site after i sold my sub. im not sure if you will need the extra spl from 2 subs as i think one pb13 ultra is enough for your size room.
hope this helps
