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 $1,199, $100 less than the PSA XS15 at $1,299, whose 15-inch sealed 550W design reaches the Bassaholic Large Room category.
Buy the SVS SB-3000 if you want one new; the Power Sound Audio (PSA) XS15 is discontinued, so only look for it used.
