Three-Driver, Dynamic Balance Speaker Array with Phase-Optimized Cascading Crossovers
Whether upgrading your home theater setup with an advanced Atmos configuration or wanting to enjoy music from the latest hi-res streaming services, Signature Elite ES50’s three-driver Dynamic Balance speaker array with 2.5-way cascading crossovers, ensures a seamless, lifelike soundstage and wide sweet spot—no matter what you're listening to or where you're sitting in the room.
Exclusive Polk Power Port for Deep Bass Extension
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.
Signature Details and Modern Styling
Dual, gold-plated five-way binding posts ensure the most direct, efficient, and lossless connection possible. The speaker tower feet have been designed for both carpet and hard floors, and are customized for improved stability and bass coupling enabling flexible placement. And Signature Elite's modern, bold look will make a statement with any home decor—available in stunning black, elegant white-washed, or contemporary walnut finishes.
Five Decades of Speaker Engineering, Backed by a Five-Year Limited Warranty
The Signature Elite Series is the culmination of five decades of Polk's premium speaker engineering (Est. 1972) and was designed at our original facility outside of Baltimore, MD. We rely on our patented Dynamic Balance Array process to pinpoint and eliminate electroacoustic 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 ES50 with a limited five-year warranty to ensure years of listening pleasure.
