Short answer: the Monoprice SW-15. It ranks #13 of 145 subwoofers by sound quality at $374.99; the MartinLogan Abyss 10 ranks #132 and costs $1899.99, so there is little reason to consider the other one.
What the Monoprice SW-15 offers: 15-inch ported with 600W RMS (800W peak) delivers Large-room Bassaholic rating. Unrivaled mid-bass punch for $375. Strong output with clean control. Dual speaker-level inputs and 40-150Hz crossover for flexible hookup. Watch for: Budget-tier design, ported room gain dependency, 30 kg mid-size, and limited dynamic headroom.
What the MartinLogan Abyss 10 offers: Independent CEA-2010 testing records 93.5 dB at 20 Hz and 106.4 dB through 40-80 Hz. The sealed enclosure combines a 10” active driver with dual 10” passive radiators in a compact 15” cube. Anthem Room Correction (ARC) and wireless streaming simplify integration. Watch for: Most controls, including low-pass frequency and phase, require the smartphone app, with sparse physical controls on the unit itself.
Buy the Monoprice SW-15. It ranks higher for sound quality than the MartinLogan Abyss 10 and costs less, which settles it without a real tradeoff to make.
If sound quality matters at all to you, skip the MartinLogan Abyss 10. It ranks near the bottom of the 145 subwoofers, so look higher up the list instead.
