SPEAKER SPECS Driver Technology Dynamic Balance: 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. Aerated Polypropylene Woofers: Each speaker uses an Aerated Polypropylene woofer cone for wide response and low distortion. For superior durability, the woofers use rubber surrounds. 1" Ring Radiator Tweeters: Each speaker features a 1" Ring Radiator tweeter for crisp, transparent highs. The ultra-light woven Ring Radiator Diaphragm delivers flat response, precise detail and overall accuracy. A High Frequency Waveguide prevents phase cancellations for smooth, uniform frequency response and wide dispersion. A Low Frequency Waveguide promotes laminar airflow between chambers to prevent air turbulence. This feature serves the same function as Power Port for Polk's bass systems. Cast Aluminum Driver Baskets: Cast aluminum driver baskets resist flexing and "ringing" for ultra-tight bass and coloration-free midrange. Cascade Tapered Crossovers: The Cascade Tapered Crossover array in each speaker ensures flat midrange response and improves imaging focus, and depth. One driver is crossed over much lower in frequency and is in essence a bass-only driver. Only one driver plays the upper midrange frequency range thereby eliminating the interference effects between the two drivers. This gives you the dynamic impact of double drivers with the accuracy and life-like imaging of a single driver system. Frequency Response Note: The overall frequency response is 38Hz-27kHz and the -3dB frequency response is 50-26kHz. Enclosure Design Acoustic Resonance Control (ARC): Internal cabinet resonance can impart a "thick" character to voices. Polk's patented Acoustic Resonance Control port system overcomes this problem. In addition to the Power Port venting system, each speaker has a front-firing port that is tuned to suppress the internal cabinet resonance, resulting in smooth, natural midrange reproduction. Low-diffraction Grilles: The speakers employ open architecture low-diffraction grilles for spacious imaging. Power Port Venting System: Each speaker has a rear-firing Power Port venting system built into its back plate for precise deep bass response. This venting system allows air velocity to slow gradually, vastly reducing air turbulence, and delivering greater bass efficiency than conventional ports. Connections Dual 5-Way Binding Posts: Each speaker has two sets of gold-plated 5-way binding posts connected by gold-plated jumpers. Using the dual 5-way binding posts, you can bi-amp or bi-wire the speakers
