From the Manufacturer

Exceptional sound anywhere you want it – really, anywhere. The compact Atrium® 4 Outdoor Loudspeaker meets or exceeds military specifications for environment endurance. Its small size makes it ideal for tight, out-of-way installations: by the pool, next to the deck or patio, around the kitchen, tucked away in the family den or filling the backyard with great sound. The easy to mount Atrium 4 will deliver high performance audio fall, winter, spring and summer, bringing years of outdoor enjoyment. Available in durable, weatherproof black or white paintable finishes.

Key Features

• 4 1/2" (11.43cm) Dynamic Balance® long-throw mineral-filled polypropylene cone driver with butyl rubber surround pumps out surprising bass response from a compact design.
• 3/4" (19mm) Dynamic Balance anodized aluminum dome tweeter with rubber surround and neodymium magnet for better power handling and smoother response.
• Broad coverage baffle design fills a large open outdoor space with big, full-range sound. The Atrium 4 has a more steeply-angled baffle design that maximizes critical mid- and high-frequency dispersion over a large area, without sacrificing detail.
• Speed-Lock® Mounting, the easiest, fastest and safest of all mounting systems.
• Polk Audio All-Weather Certified, 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.) Polk All-Weather Certification means Atrium Speakers can effortlessly withstand the worst mother nature can dish out, whether its extreme temps or heavy rains.

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® 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.
