Short answer: the SVS SB-3000 for output and accuracy at a lower price. Its 13-inch sealed driver with 800W RMS (2500W peak) delivers 118.7dB average with exceptional accuracy, though its compact 25 kg (55.1 lbs) cabinet limits bass extension and room-mode dependency is noted. It costs $1099, $200 less than the PSA XS15 at $1299, whose 15-inch sealed 550W design reaches the Bassaholic Large Room category.
What the Power Sound Audio (PSA) XS15 gets right: 15-inch sealed with 550W RMS reaches Bassaholic Large Room category.
On the SVS SB-3000 side: 13-inch sealed with 800W RMS (2500W peak) delivers 118.7dB average with exceptional accuracy. The tradeoff: Ported cabinet room-mode dependency, compact 25 kg (55.1 lbs) size limits bass extension, and $1,100 investment.

SVS SB-3000: $1,099.00 Amazon eBay
Pros: 13-inch sealed design with 800W RMS (2500W peak) that Audioholics measured at a 118.7dB CEA-2010-A average from 40-80Hz, and rated by SVS at 18-270Hz within ±3dB. Beautifully made with pinpoint control and flawless tonal accuracy. Sweet spot performance-to-value ratio. Three-band parametric EQ with 1Hz precision adjustment.
Cons: Being sealed, it gives up deep-bass output: Audioholics measured 96.6dB at 20Hz and 101.7dB at 25Hz, about 15dB behind the ported SVS PB-3000 from the same series, so a large room or reference-level movie bass may call for a second sub.
