A strong, rigid and acoustically inert enclosure built with critically damped Medite MDF and laser optimized bracing reduces internal standing waves and resonances for less coloration and distortion of your sound.
ES50’s Hi-Res Audio Certified, Terylene dome tweeter provides crystalline highs (40kHz+) ideal for enjoying high resolution music from services like Apple Music, Tidal, Amazon Music HD, Qobuz and Spotify HiFi, along with the soundtracks of the latest ultra-hd movies.
You’ll experience a seamless, lifelike soundstage no matter where you’re seated thanks to Signature Elite ES50’s Dynamic Balance mica-fortified, polypropylene woofers and 2.5-way cascaded crossover array.
Power Port is a Polk-patented design that smoothly transitions the airflow from the speaker’s port into the listening area to eliminate turbulence and distortion for louder, deeper, more musical bass and a more open and transparent midrange. When paired with the ES50’s dual 5.25” woofers, that means effortless bass you can feel.
ES50 Towers deliver spacious, clear, enveloping and realistic sound reproduction from nearly any amplifier or receiver—whether 4- or 8-ohm, vintage audiophile or the latest Dolby Atmos or DTS:X surround sound AVRs.
ES50 is designed for you to hear pure sound the way the director, producer or artist intended.
Signature Elite Series is the culmination of five decades of Polk’s premium loudspeaker engineering and were designed at our original Acoustic Research and Development facility in Owings Mills, Maryland.
Our goal since our founding in 1972 has been to build great loudspeakers that transport you to the scene of the recorded performance. Later with the advent of home theaters, to make you feel that you’re in the center of the action. We’ve achieved this by constant innovation and by leaving nothing to chance. The result of this 50-year engineering heritage is best-in-class loudspeakers backed by numerous awards, patents, and fans like you.
All Polk loudspeakers are built to last. We rely on an exclusive Dynamic Balance Array process to pinpoint and 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 Series with a 5-year limited warranty to ensure years of listening pleasure.
With Polk Signature Elite loudspeakers, you’ll enjoy movies, music and gaming with high-resolution, room-filling sound with effortless bass. Hi-Res Audio Certified, accessibly priced, and built to exceed our patented quality-testing process, the Signature Elite series fulfills the Polk promise of great sound for all.
