I updated my potential subwoofer list. Based on recent feedback, I think I should stick with buying at least a pair of subs. I'm removing the PB13 Ultra and FV15HP because a pair of those would be too far outside my budget. The XV15's and PB12-NSD's are both discounted if bought in pairs.Subwoofer Performance CEA Standard (THD <10%, 2 Meters) SPL @ 20/32/40/50/63Hz:$769 $725

I'm leaning towards either a pair of PB12-NSD's or a pair of XV15's. It seems like the PB12's have a more accurate sound, but the XV15's put out more sound. In fact, Audioholics
said the following about the XV15's:
The Power Sound XV15 easily meets the required output thresholds to receive the Audioholics Bassaholic Large Room rating, but was just a little short of making the more difficult Extreme room rating. It would have been the least expensive unit to do so by far. The Large room rating indicates that this sub is recommended as maintaining adequate headroom in rooms or spaces of between 3,000 to 5,000 cubic feet and/or for users who usually listen at moderate to high volume levels.
My thoughts are that if a single XV15 almost makes it into the 5000+ cubic feet category, I can only imagine that I'd be satisfied with *two* of those. I guess it comes down to how much I should be concerned about the accuracy difference between the PB12 and XV15 - I don't know how much this would affect me. My guess is that if I'm not using this for music listening, that I should go for the raw output. Does that sound right? Or is there a certain level of distortion that would be problematic even for movies?
Here's the measurements from Audioholics.
