Polk perfected the method of analyzing a speaker's microscopic behavior while in motion using laser Interferometry. With that information in hand, Polk engineers select the ideal combination of materials, geometry and construction techniques to literally "tune out" unwanted resonance. The result is a speaker that delivers pure, distortion free deep bass. Klippel Transducer Optimization. Using a state-of-the-art Klippel Distortion Analyzer, Polk engineers optimized the transducer's motor structure, voice coil alignment and suspension for longer excursion and greater linearity bringing you the best possible performance even at the most extreme listening levels. Speed-Lock® Mounting System. Our proprietary system for easy, safe one-handed installations even in difficult locations. The greatly simplified mounting procedure means the end to "juggling" at the top of the ladder. Simply mount the bracket and click the speaker into place. Aim it, tighten it down, and fini! Outdoor convenience, indoor sound quality! The new bracket also has a 45-degree down angle. Why adjust a speaker to a 45-degree angle, when we can design a mounting bracket that lets you install the speaker at that angle permanently? It's another feature of Atrium's new mounting system and a simple, elegant solution.

(If you're not sure a dealer is "authorized," call Polk Audio at 1-800-377-7655, and ask us.) The warranty is not transferrable, that means it applies only to the original purchaser. If you purchase your speakers from a private individual, that product is considered "used" and has NO factory warranty, no matter what the seller implies. The warranty is VOID if the serial number of the speaker has been removed or defaced. If you have any questions about your warranty coverage, or you think you need service, call Polk Customer Service at 1-800-377-7655. We're here to help you get the most from your new speakers!
