Several choices with a thousand dollar budget (we are using three RW-12d's) and that is, on sale at Newegg, buy three RW-12d's and later deal with selling or giving the RW-12d's away so as to deal with expected upgrading hassles or live with their short comings as you find you want/need deeper response; those <20Hz sound waves that you find you can't live without.
(the above purchase is fraught with hassles; loss of time and money yet offers the much desired immediate gratification)
One can buy two Rythmik, LV12R's and add a third with next years tax refund. But one may find themselves wanting more and find themselves feeding the upgrade beast.
One can buy two SVS, PB-1000's and add a third with next years tax refund. But one may find themselves wanting more and find themselves feeding the upgrade beast.
One can buy one SVS, PC-12NSD and over the next couple of tax returns, add a second and/or third subwoofer of equal, like, kind and quality.
One can buy one PSA, XS15 or XV15 (I prefer the sealed version) and over the next couple of tax returns, add a second and/or third subwoofer of equal like, kind and quality.
(the last two recommendations eliminates most need to upgrade and in my opinion, is the best expense of money)
The last two choices (as eljay suggested) allows one to make a really good choice in subwoofer, see what's what with what and, as they're able, should they want, over the next couple of years, add a second and/or third subwoofer.
(the upgrade beast is a terribly hungry beast indeed and the idea is to leapfrog the beast and get on with the show)
In the end, it's all about the Benjamins and how many one has to throw at the beast to make it go away.
As to the XS30 being better, I think not. Why, more output yes but a single XS30 will not do anything to smooth out a room's acoustical response to the subwoofer's output and you'll find yourself wishing you had purchased three lesser subs like three XS15's or you'll find yourself needing a second or third XS30 wondering why did you buy the XS30 in the first place as now you know better as you've learned more about how rooms respond to subwoofer output.
Bad news, subwoofers are the most enigmatic of the sound reproductions set due to the length of their reproduced sound waves and how they like to fight and get along with each other (cancellation/reinforcement) due to a room's acoustical response to their output.
