Short answer: the Monoprice Premium Select 8in 200-Watt. It ranks #33 of 48 subwoofers by sound quality at $224.99; the JL Audio Dominion d108 ranks #37 and costs $1100, which makes this an easy call rather than a real tradeoff.
What the Monoprice Premium Select 8in 200-Watt offers: 8-inch ported driver still manages 106.4dB CEA-2010-A average at the lowest price of any subwoofer tested in this weight class. An easy entry point for a first subwoofer. Watch for: Very compact 8.4 kg size, limited 106.4 dB output, ported room interaction, and entry-level build.
What the JL Audio Dominion d108 offers: Independent CEA-2010 testing records 79.7 dB at 20 Hz and 103.0 dB through 40-80 Hz. The sealed enclosure with 8” (203mm) driver is best suited to upper-bass support in a modest room. Watch for: Deep-bass output is limited relative to its midbass result, so it is not the right choice for the lowest movie effects. The 288.8H x 254.0W x 336.0D mm cabinet and 12.0 kg mass still need deliberate placement and calibration.
Buy the Monoprice Premium Select 8in 200-Watt. It ranks higher for sound quality than the JL Audio Dominion d108 and costs less, so the other one has nothing left to offer.
If sound quality matters at all to you, skip the JL Audio Dominion d108. It ranks near the bottom of the 48 subwoofers, so look higher up the list instead.
