These floor standing speakers, the Polk Signature Elite ES50, let movie lovers enjoy movies, gaming, and multi-channel music in high-resolution cinematic sound thanks to their high-performance, compact design. Engineered for discerning audiophiles and homeowners, the Dynamically Balanced acoustic array pairs a 1” High-Resolution Terylene Tweeter, two 5.25” Mica-Fortified Polypropylene Woofers, and 2.5-Way Cascading Crossovers to deliver crystal-clear, highly detailed sound with the energy of live music—no matter what you’re listening to or where you’re sitting in the room. Polk’s patented Power Port Bass Enhancing Technology extends the overall bass port and provides greater surface area for distortion-free, louder, more musical bass impact. These surround sound speakers are Hi-Res Audio Certified and ensure accurate sound reproduction from even the latest Dolby Atmos and DTS:X AVRs and amplifiers. The Signature Elite Series is designed with quality, timbre-matched Polk components to enable you to mix and match models and build your dream home theater or music-listening environment. Add the Signature Elite ES10 surround pair, ES30 center channel, and any sub for a complete 5.1 surround setup.
