Short answer: a size-versus-depth tradeoff. The Monoprice SW-15 is a 15-inch ported sub with 600W RMS (800W peak) and a Large-room Bassaholic rating, but limited dynamic headroom and a 30 kg (66.1 lbs) cabinet. The SVS PB-1000 PRO is a ported 12-inch with 325W RMS that reaches 17Hz, so it is the one to pick if the deepest bass is the priority.
Buy the Monoprice SW-15. It is rated higher for sound quality than the SVS PB-1000 PRO and costs less, which makes it the one to get unless you need something the other one does better.
