No matter how you like to play outdoors, there's an Atrium Loudspeaker that loves to play and play and play and play and play.
The new Atrium Series offers five new models, with sonic improvements specifically engineered for better outdoor performance. In fact, our engineering and industrial design teams spent months looking at any and every detail that could make these new Atriums perform better, mount faster and be even more reliable. When you set out to improve a loudspeaker with the pedigree of the Atrium Series, every detail counts.
NEW Speed-Lock™ Mounting System
for easy, safe one-handed installations even in difficult locations. The greatly simplified mounting procedure means fewer parts to "juggle." Simply mount the bracket and click the speaker into place. Aim it and tighten it down, and fini! Outdoor convenience, indoor sound quality!
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.
Superior Polk Audio Technologies
Dynamic Balance® A Polk perfected method of analyzing a speaker's microscopic behavior with laser Interferometry. Polk engineers can tune out unwanted resonance and distortion with the right combination of materials, geometry and construction techniques. This brings you pure, distortion-free sound.PowerPort® PowerPort technology allows Polk Audio speakers to deliver more deep, musical bass than you'd expect from a moderately-sized (and moderately-priced) loudspeaker. It's the kind of realistic bass that reaches out and grabs you, shakes your behind on the seat, and adds true depth and visceral emotional power to your music and movie experiences.Klippel Optimization By using a state-of-the-art Klippel Distortion Analyzer, Polk engineers were able to optimize the woofer's motor structure, voice coil alignment and suspension bringing you the best possible performance even at extreme listening levels.
