Make Your Entire Home Theatre the Sweet Spot
You’ll experience a seamless, lifelike soundstage no matter where you’re seated thanks to Signature Elite ES50’s Dynamic Balance polypropylene woofers and 2.5-way cascaded crossover array.
Effortless Bass
Polk’s patented Power Port design provides greater surface area and smoother air flow for more output and less distortion compared to conventional ported speakers. When paired with the ES50’s dual 5.25” woofers, that means effortless bass you can feel.
From Vintage Hi-Fi to Dolby Atmos & DTS:X
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.
Built For Pure Sound
ES55 is designed for you to hear pure sound the way the director, producer or artist intended.
Quiet Cabinet
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.
Low-Interference Grille
The ES55’s anti-diffraction, magnetic grille minimises sonic interference and can be easily removed to provide a striking look.
Direct Connection
Dual gold-plated five-way binding posts ensure the most direct, efficient, and lossless connection possible.
