Short answer: the SVS SB-2000 Pro for power, the Monoprice SW-12 for budget output. The sealed 12-inch SVS runs 550W RMS with a 1500W peak Sledge amplifier. The Monoprice is ported, with 400W RMS (600W peak), 112.3 dB output capability and clean tight transients, though entry-level build and ported room interaction are the catch.
Buy the Monoprice SW-12. It is rated higher for sound quality than the SVS SB-2000 Pro and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
