Short answer: a tie on sound quality. Both are rated 3.2/5 (#134 and #132 of 145 subwoofers), so choose on features and fit.
Why pick the BK Electronics XLS200-DF MK2: Compact sealed 10-inch with 275W delivers deep extension and bogglingly potent output for size.
What the MartinLogan Abyss 10 does well: Independent CEA-2010 testing records 93.5 dB at 20 Hz and 106.4 dB through 40-80 Hz. Watch for: Most controls, including low-pass frequency and phase, require the smartphone app, with sparse physical controls on the unit itself.
Buy the BK Electronics XLS200-DF MK2 or the MartinLogan Abyss 10 on features: they are rated the same for sound quality at close to the same price.
