Same family: the Monoprice SW-10 (smaller subwoofer, ranked lower, estimated 3.7/5) and the Monoprice SW-12 (smaller subwoofer, ranked higher, rated 4.2/5).

Pros: A big 15 inch subwoofer with powerful, punchy bass at a budget price, great for movies in a large room. 15-inch ported with 600W RMS (800W peak) delivers Large-room Bassaholic rating. Unrivaled mid-bass punch for $500. Strong output with clean control. Dual speaker-level inputs and 40-150Hz crossover for flexible hookup.

Cons: Budget-tier design, ported room gain dependency, 30 kg mid-size, and limited dynamic headroom.
