Polk Audio MXT12 / XT12 12″ High-Performance Subwoofer

Add Polk’s legendary, effortless bass to your home audio setup with the MXT12 / XT12 12″ High-Performance Subwoofer. Designed for music, movies, TV, and gaming, it delivers deep, clean, and powerful low frequencies with minimal distortion. Featuring a long-throw, high-excursion 12” dynamic balanced woofer with a bi-laminate paper cone and foam surround, it produces smooth bass down to 24Hz.

Powered by a 100W Class AB amplifier (50W RMS), the MXT12 offers loud, responsive performance while maintaining clarity. Fine-tune your sound with adjustable volume, low-pass crossover (80–160Hz/LFE), and phase control (0/180°). The bass-reflex (ported) cabinet is built from critically braced, low-resonance MDF with permanently installed feet and a removable precision-fit grille for pure audio reproduction. Timbre-matched with the Polk Monitor XT series, it integrates perfectly with any system. For even more impact, pair two MXT12 subwoofers for richer, smoother low frequencies.
