Short answer: the Monoprice SW-15. It ranks #13 of 145 subwoofers by sound quality at $374.99; the JL Audio Fathom f110 ranks #139 and costs $2299, 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 JL Audio Fathom f110 offers: Compact sealed 10-inch punches well above weight class with fast detailed musical bass. Advanced D.A.R.O. room optimization with 18-band EQ. Flawless gloss-black finish and precise realistic impacts. Watch for: No detailed measurement caveats are currently recorded.
Buy the Monoprice SW-15. It ranks higher for sound quality than the JL Audio Fathom f110 and costs less, so the other one has nothing left to offer.
If sound quality matters at all to you, skip the JL Audio Fathom f110. It ranks near the bottom of the 145 subwoofers, so look higher up the list instead.
