We have some shipping right after the Holiday.
I have not had Ricci test it so I can't make a comparison within a few db.
I suggested the UXL as only a ballpark and again, it would be hasty to try and estimate things within a few db. There could be quite some variance due to T/S differences, although physically similar.
So in short: it is premature to try and slice up number racing with subs listed on data-bass.com.
You'd be comparing phantom numbers.
In general, I don't like the "this sub is 2 db louder than this sub at this frequency etc" discussions because it would be hard to buy something and say "wow this sub is great but I'm really missing those 2 db more I could get at 16hz before the driver bottoms out. I keep reaching the limits of my sub and man, those 2 decibels would just put it over the top and I would be set!".
In reality, no-one really does that.
What I can confidently say is that if the poster is looking for more all around performance not just better subsonics, the PS18x probably delivers much more overall output vs a single 15" ported sub, especially above and below the tuning point. Above 30 hz the headroom is probably quite noticeable. The measurements for our two 15" models are online and I can say that this combination dwarfs both of those units over the whole bandwidth hand-idly.
If simply more subsonic performance is the only thing he feels is lacking, then looking simply at 12hz performance would be a big indicator. But the way I read it, it was an overall jump, including subsonics desired (maybe I'm wrong?). Being that the XS15se is pretty darn stout, I doubt switching to another two single 15" ported design boxes will give him all the performance jump he wants.
I would say the same thing about our PV-15x which measures a little higher but just behind the FV15hp. I always like to think that an upgrade, especially where one has to dig into the wallet and move around some big heavy boxes, should not be subtle.
Something like the Captivator ported would also probably be a great solution.
But then the box size comes into play if that matters.
If subsonics were not a main concern, I still like the idea of quad XV15se's in that space as well.
