Short answer: the Focal Sub Air if sound quality matters most, the Monoprice Premium Select 8in 200-Watt if price matters most. The Focal Sub Air ranks #23 of 48 subwoofers at $1399. The Monoprice Premium Select 8in 200-Watt ranks #33 at $224.99, $1174.01 cheaper.
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 Focal Sub Air offers: Independent CEA-2010 testing records 109.0 dB through 40-80 Hz. The ported, side enclosure with 8” (203mm) driver is intended to add useful bass support without a full-size cabinet. Watch for: Without a published 20 Hz output result, deep-bass capability is less certain than its midbass figure. The 408.9H x 360.7W x 160.0D mm cabinet and 7.7 kg mass still need careful placement and calibration.
Buy the Monoprice Premium Select 8in 200-Watt if the price is the priority over sound quality, or the Focal Sub Air if sound quality is the priority over the price.
