Short answer: the PSA XV15-BASE for measured output, the Monoprice SW-15 for price. The PSA’s 15-inch ported driver delivers a 119.1dB CEA-2010-A average from a rear-ported cabinet. The Monoprice SW-15 is also 15-inch ported with 600W RMS (800W peak) and a Large-room Bassaholic rating, but budget-tier build, ported room-gain dependency, a 30 kg (66.1 lbs) cabinet and limited dynamic headroom hold it back.
Buy the Monoprice SW-15 new; the Power Sound Audio (PSA) XV15-BASE is no longer sold new, so it only makes sense as a used find.
