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 mixture of materials, geometry and construction processes to literally "tune out" unwanted resonance. The effect is really 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 extended excursion and greater linearity bringing you the most beneficial performance even in 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" with 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 features a 45-degree down angle. Why adjust a speaker to your 45-degree angle, when we can design a mounting bracket that lets you put in the speaker as well angle permanently? It's another feature of Atrium's new mounting system along with a simple, elegant solution.

1To ensure a valid warranty, Polk loudspeakers has to be purchased with an Authorized Polk Audio home or car loudspeaker Dealer (such as Amazon.com). (If you're unsure a dealer is "authorized," call Polk Audio at 1-800-377-7655, and have us.) The warranty is not transferrable, that means it applies only to the original purchaser. Should you get your speakers coming from a private individual, that strategy is considered "used" and has NO factory warranty, regardless of what the seller implies. The warranty is VOID if the serial number of the speaker continues to be removed or defaced. If you have questions about your warranty coverage, or you imagine you will need service, call Polk Customer Care at 1-800-377-7655. We're here to help you you obtain the most from the new speakers!
First introduced in 2002, the outdoor Atrium Series set a fresh standard not limited to build quality, but sonic performance, too. But we couldn’t leave sufficiently alone. Not merely does our new, refined Atrium Series offer better sonic performance and much easier install/mounting options, the series also exceeds the typical military specification weather tests, setting a brand new standard for rugged outdoor durability under our very own more rigorous weatherproofing certification program. The results really are a pure joy to listen to. So that wherever you place your Atrium speakers—by a pool, on a deck or in the sunroom, you may be confident they’ll deliver great sound year round.
Atrium Series Speakers exceed baseline industrial and military specifications for environmental endurance (ASTM D5894-UV Salt Fog, Mil Standard 810 Immersion, Mil-Std 883 Method 1009.8 for salt and corrosion.)
Anodized Aluminum Tweeter Domes with Rubber Surrounds are absolutely immune to the elements, provide the smooth, broad high-end range you need for larger outdoor spaces
Newly designed tweeter phase cap smoothes the frequency response from 12KHz up to 20kHz, the last audible octave.
Broad Coverage Baffle Design adapted and applied from our current Atrium design but a more steeply-angled baffle design that maximizes critical mid- and high-frequency dispersion over a large area.
Speed-Lock Mounting System for easy, safe one-handed installations even in difficult locations. The greatly simplified mounting procedure means fewer parts to ?juggle.?
