Once both subs reach their output limits, the XV would keep getting louder. But @ 15 below reference, the SVS has less roll off below 25 Hz. Room gain will have the same effect on both subs. The shallower roll-off will hit harder up until the point that the PC2000 hits its limiter.

I say this because I think the XV15se rolls off a little bit more below 25 Hz. So at 15 below reference, the PC2000 will hit just as hard or harder. At higher levels, especially on music, the PC2000 won't have as much output.
So these two quotes of yours got my hopes up, because one thing I wasn't loving about the PSA XV15se (other than its looks) was its performance with subtle bass or listening at moderate volumes. After hooking it up today, I really have to agree with you, or at least that's what my ears say. When turned up to reference level, the XV15se does shake the house a little more and digs deeper and harder (which is expected), but it's not by as big of a margin as I was expecting. However, at level lower than reference, I really think the PC-2000 sounds better. I've gone back and forth several times, and it's a much bigger difference than I was expecting. I think it even sounds better at reference if it's not a big earth shaking bass scene.
One thing I missed when I pulled out my little Martin Logan 10" Dynamo and replaced it with the PSA was the sort of smooth and seamless filling bass when the volume wasn't cranked all the way up. It really blended so well with my Def Techs. I figured that was a sealed sub thing and I was going to just have to give that up for big bass. Well, the PC-2000 handles the low volumes even better than the Dynamo, which I wasn't expecting, and I'm surprised at how much better it sounds than the PSA almost all of the time.
I set them up the same. They are in the same spot, with the same cross over settings in my Denon, and I've recalibrated in-between every time I switch, and the SVS sub just sounds better to me. Even when it's cranked, and the PSA beats the SVS on output, the SVS still blends in better. I'm not an audiophile so I don't know exactly why, but in my family room with my setup, I vastly prefer it. I am super happy right now! I'm only a few hours into my 45 day trial, and I don't see this thing going back. Funny... bigger isn't always better, and I'm guessing that every sub behaves different in every room.
Best of all, it passes the WAF!
