Short answer: the Monoprice SW-12. It ranks #6 of 212 subwoofers by sound quality, rated 4.2/5, at $364.99; the BIC America PL-300 ranks #89, rated 3.7/5, and costs $449, so there is little reason to consider the other one.
The Monoprice SW-12 is the better-sounding pick. A budget 12 inch subwoofer that hits hard with clean, tight bass and easy connections. The tradeoff: Entry-level build quality, ported enclosure room interaction, and lower 112.3 dB output capability.
Why pick the BIC America PL-300: An affordable ported 12 inch subwoofer with three ports, adjustable tuning and a strong amplifier. The tradeoff: At 48.1 lbs (21.8 kg) and 457 x 387 x 476mm it is a large, heavy cabinet that needs floor space.
Buy the Monoprice SW-12. It is rated higher for sound quality than the BIC America PL-300 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
