The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other AV receivers and amplifiers, soundbars, home theater speakers, subwoofers, surround sound systems and Blu-ray players we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
["The MXT12 is part of Polk Audio's entry-level home theater line and carries a 12-inch driver paired with a 100W built-in amplifier. At 39 lb and 16 x 18 x 16 inches it is a solid, compact cabinet. RCA connectivity keeps integration simple with any AV receiver that has a subwoofer pre-out.", "At $359, the MXT12 sits in a competitive bracket against Klipsch and Dayton Audio options with higher stated power. Polk's drivers are tuned for musical bass rather than raw SPL, which tends to produce a tighter, less boomy low end that integrates well with full-range speakers in smaller rooms.", 'With 252 reviews and a 4.6 rating, buyer feedback is broadly positive. That volume of reviews gives the score real weight, and complaints tend to center on shipping packaging rather than performance. For a first home theater subwoofer upgrade, it is a reasonable starting point.']

Performance notes
The 12-inch driver and 100W Class D amplifier are adequate for moderate listening levels in small to medium rooms. The floor-standing RCA-connected design fits standard home theater setups. At 39 lb, the cabinet has the mass to minimize unwanted resonance, which aids bass quality.
What buyers say
A 4.6 rating from 252 buyers is a strong signal for a sub-$400 subwoofer. Most feedback highlights solid bass impact and easy setup. The review volume is enough to treat this score as reliable rather than a result of a small sample.

Frequently asked questions
Does the Polk Audio MXT12 work with any AV receiver?
Yes. It uses a standard RCA LFE input, which is the subwoofer pre-out found on virtually every AV receiver made in the last 20 years. No special setup is required beyond running an RCA cable from your receiver to the subwoofer.
Is 100W enough power for a home theater subwoofer?
It depends on room size and how loud you listen. In rooms up to roughly 250 to 300 square feet, 100W with a 12-inch driver is generally adequate for movies and music at normal listening levels. Larger rooms or high-volume listening may benefit from a higher-powered option.
How does the MXT12 compare to the Klipsch R-12SW at a similar price?
The Klipsch R-12SW carries a 400W amplifier versus the MXT12's 100W, which is a meaningful difference on paper. Whether that translates to audible output in your room depends on your setup. The MXT12's 4.6 rating from 252 buyers is competitive with Klipsch's track record, so both are worth considering.
