Polk MXT12SUB Subwoofer
The Polk Monitor XT12 is a powered subwoofer for a music or home-cinema system that needs a larger dedicated bass foundation. The 12-inch Dynamic Balance driver and ported cabinet are designed to bring more weight and impact to soundtracks, games and music.
Room integration is built into the design: the adjustable crossover, phase and volume controls help the subwoofer blend with the main speakers instead of simply adding uncontrolled bass.
Use its wired line-level, LFE or speaker-level connections with a compatible receiver or amplifier. The specific connections and adjustments are listed below so the sub can be planned correctly before installation.
