Experience immersive cinematic surround sound in a spacious, enveloping soundstage with Polk Signature Elite ES50 Tower Speaker. Featuring a dynamic balanced acoustic array with a 1” High-Resolution Terylene Tweeter, two 5.25” Mica-Fortified Polypropylene Woofers and Precision Crossovers, this speaker delivers pristine highs, detailed midrange, and offers a realistic reproduction of surround effects and ambient sound for all your movies, music, and video games. Additionally, the patented Polk Power Port Technology extends the overall bass port, providing greater surface area to eliminate turbulence and distortion for louder, deeper, more musical bass impact. With high sensitivity and 4 & 8 Ohm compatibility, the ES50 delivers realistic sound from nearly any amplifier or receiver—including the latest Dolby Atmos and DTS:X surround sound AVRs and supports playback in latest high-resolution movie formats along with music streamed over services like Apple Music, Tidal, Amazon Music HD, Qobuz and Spotify HiFi. It is Hi-Res Audio Certified, and Dolby Atmos and DTS:X compatible and can be used as a rear/side speaker or as elevation surrounds for a multi-channel home theater setup. Create a complete home theater by adding other Signature Elite Series speakers (sold separately). Add the Signature Elite ES10 surround speaker pair, ES35 center channel and any subwoofer for a complete 5.1 surround setup. Elevate any home configuration and get extraordinary sound reproduction from any part of the room.
A: Hello, While the XT70 speakers are excellent, the ES50 have some updated technology that can provide an amazing soundstage. The ES50 uses the Dynamic Balance cone drivers which delivers precise low end sound output, paired with Power Port technology to enhance the bass response. The Cabinet is made from Non-resonant MDF to cut down on resonant frequencies that may occur, and the tweeter features some mechanical updates to provide clearer high resolution sound. The ES50 would be a fine upgrade for any sound system.
Q: Are these sold as a pair or individual speakers?
A: Hi Andrew, The ES50 speakers are sold per speaker, nor per pair.
Q: What are the two binding posts for?
A: Hello, As with most passive speakers, the two binding posts on the rear panel of the Signature Elite ES50 speakers are where the speaker cable from the amplifier or receiver attaches.
