Short answer: the Monoprice SW-15 for output, the Rythmik F12 for a sealed servo design. The 15-inch ported Monoprice runs 600W RMS (800W peak) and earns a Large-room Bassaholic rating, though budget-tier build, a 30 kg (66.1 lbs) cabinet and limited dynamic headroom come with it. The Rythmik is a sealed 12-inch servo with 370W RMS and excellent value.
Buy the Monoprice SW-15. Both are rated the same for sound quality, and it costs $939.01 less than the Rythmik F12.
