Dynamic Balance Drivers: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion. Using just the right materials enables Polk to eliminate issues that reduce speaker performance and tune out performance-robbing resonances before they occur. Dynamic Balance ensures a rich, clean, full-range sound no matter what you're listening to. The Polk Signature Elite ES30 center-channel loudspeaker incorporates a Dynamic Balance two-way driver array with one 1" tweeter and two 5.25" woofers.

• Hi-Res 1" Terylene Tweeter: The Signature Elite ES30 center-channel loudspeaker utilizes Polk's newly designed 1" Terylene tweeter to deliver clear and detailed high-end response for improved vocals in movies and music. It will support high frequencies up to 40kHz to perfectly reproduce the latest high-resolution audio files with improved audio extension, earning Hi-Res Audio Certification.
• Two 5.25" Mica-Reinforced Polypropylene Woofers: The Signature Elite ES30 center-channel speaker employs two 5.25" Dynamic Balance low distortion mica-reinforced polypropylene midrange cone woofers for clean, clear bass, better linearity, and increased dynamic midrange. These mica-reinforced polypropylene midranges feature butyl rubber surrounds, massive ceramic motor structures, and high-temperature Conex fiber spiders that combine to create drivers of exceptionally high efficiency, for clean, clear bass, better linearity, lower distortion, and greater durability.

Phase-Optimized Precision Crossover: The Signature Elite Series center-chanel loudspeaker employs a high-performance two-way, phase-optimized precision crossover (2.8kHz) for seamless blending and optimum time alignment of the tweeter & woofers, creating a lifelike soundstage.

Power Port Technology: The Signature Elite ES30 center-channel incorporates Polk's Power Port technology with one specially designed rear-firing port. Power Port technology smoothly transition air flow from inside the speaker into your listening area for deep, extended bass impact while minimizing turbulence and distortion. Polk's patented Power Port technology delivers 3dB more bass response than a traditional ported speaker.

Non-Resonant Enclosure: The center-channel speaker's strong, rigid and acoustically inert enclosure reduces unwanted internal standing waves for less audible coloration. And non-resonant Meddite MDF construction, extra bracing, and a thick front baffle ensure a more lifelike sound. The enclosure's curved edges not only look cool, they reduce standing waves inside the cabinet for less audible coloration. The enclosure comes in a beautiful black, white, or walnut wood-grain vinyl finish.

Anti-Diffraction Magnetic Grille: The Signature Elite ES30 includes an anti-diffraction magnetic grille for unaltered sound. The integrated magnets make it easy to attach and remove the grille from the center speaker.

5-Way Binding Posts: The center-channel loudspeaker features 5-way binding posts for a secure connection to your speaker wire. The 5-way binding posts will accept bare wire (up to 10AWG), pin-connectors, spade-connectors, and banana plugs (single or dual). The speaker terminals are color coded for easy identification between positive (red) and negative (black). The speaker is 8-ohm rated.

Placement & Mounting Options: The Signature Elite ES30 center-channel loudspeaker can be mounted horizontally, under or above your flat-panel TV. You can simply place the center-channel speaker on a table-top or shelf. The speaker should be centered with the screen of your television. The included rubber increase the height of the speaker by 0.125".
