Technology
Dynamic Balance®. 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® ing System. Our proprietary system for easy,
safe one-handed installations even in difficult locations. The
greatly simplified ing procedure means the end to "juggling"
at the top of the ladder. Simply the bracket and click the
speaker into place. 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 ing bracket that lets you install the
speaker at that angle permanently? It's another feature of
Atrium's new ing system and a simple, elegant solution.
