Polk Audio Signature Elite ES20 Bookshelf Speaker - Hi-Res Audio Certified,Dolby Atmos & DTS:X Compatible, 1

Exclusive Polk Power Port for Effortless Bass

Power Port is a Polk-patented design that smoothly transitions the air flow from the speaker's port into your listening area. It also extends the overall bass port, providing greater surface area to eliminate turbulence and distortion for louder, deeper, more musical bass impact. On average, Power Port provides 3dB louder bass output than conventional ported loudspeakers.

Built for Pure Sound

Gold-plated five-way binding posts ensure the most direct, efficient, and lossless connection possible. Strong, rigid and acoustically inert enclosure that reduces unwanted internal standing waves for less audible coloration. Non-resonant, critically damped Medite MDF construction ensures low distortion for a more lifelike sound. Plus, the ES20's anti-diffraction, magnetic grille minimizes sonic interference.

Five Decades of Speaker Engineering

The Signature Elite Series is the culmination of five decades of Polk's premium speaker engineering (Est. 1972) and were designed at our original facility outside of Baltimore, MD. We rely on our patented Dynamic Balance Array process to eliminate electro-acoustic and mechanical issues before they become a part of the finished speaker. We're so confident of this process, that we back the Signature Elite ES20 with a limited five-year to ensure you years of listening pleasure.
