Short answer: the Monoprice Premium Select 8in 200-Watt. It ranks #33 of 48 subwoofers by sound quality at $224.99; the Paradigm Millenia CT ranks #45 and costs $499, so there is not much of a tradeoff to weigh.
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 Paradigm Millenia CT offers: Independent CEA-2010 testing records 99.0 dB (avg of 3/4 bands) through 40-80 Hz. The subwoofer 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 400.0H x 127.0W x 355.6D mm cabinet and 5.7 kg mass still need careful placement and calibration.
Buy the Monoprice Premium Select 8in 200-Watt. It ranks higher for sound quality than the Paradigm Millenia CT and costs less, so there is no real case for the other one.
Skip the Paradigm Millenia CT if sound quality matters to you. It ranks near the bottom of the 48 subwoofers.
