My Best Polk Audio Subwoofer Box (2018) - Buyer's Guide

Enhanced, re-engineered ring radiator tweeters extend top-end response for incredible details and realistic imaging. Polk’s exclusive dynamic sonic engine design optimizes the midrange driver and the ring radiator tweeter in separate interior chambers for improved transient response, superior imaging and greater horizontal off-axis response. Our innovative overhung voice coil design augments the excursion length for subwoofer drivers, increasing their power-handling capabilities and enhancing bass response. Klippel motor optimization uses laser measurement technology to ensure a consistent excursion path at either end of the driver’s travel for uniform performance at both low and high volumes.

Curved enclosure design employs non-parallel surfaces that not only lead to a stronger, more rigid and acoustically inert enclosure, but they also result in less audible coloration from internal surface resonances. Tl3 center channel tuned rear port maximizes the low-end response of the dual driver design for superior blending with the satellites and the subwoofer. Time lens technology-the acoustic centers of the tweeter and mid-bass driver are located in the same plane for superior imaging, while the acoustic lens incorporated in the grille smoothes the tweeter’s frequency response. The tl series creates imaging and frequency balance previously impossible in small, high performance satellite speakers.

Tl3 satellite aperiodic-tuned rear port enables better blending with a subwoofer. This design combines the bass extension of an acoustic suspension enclosure with the mid-bass boost of a ported enclosure by controlling airflow through the port for better extension without distortion.
