The ES55's Hi-Res Audio Certified, Terylene dome tweeter provides crystalline highs (up to 40 kHz), making it ideal for enjoying high-resolution music from services like Apple Music, Tidal, Amazon Music HD, and Qobuz, along with the soundtracks of the latest Ultra-HD movies.

Make Your Entire Home Theater the Sweet Spot

You'll experience a seamless, lifelike soundstage no matter where you're seated, thanks to the Signature Elite ES55's Dynamic Balance mica-fortified, polypropylene woofers.

Effortless Bass

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 ES55's dual 6.5" woofers, that means effortless bass you can feel.

From Vintage Hi-Fi to Dolby Atmos & DTS:X

The ES5 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.

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 minimizes 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.
