    Outdoor Speaker
    Driver Technology
    Enclosure Design
    Mounting Options

    Outdoor Speaker

    Weatherproof Design: 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.) Certification means Atrium speakers can effortlessly withstand the outdoors, and hold up in extreme temperatures and precipitation.

    Driver Technology

    Polk Patented Technologies: Patented Dynamic Balance and Klippel Optimization technologies ensure the perfect material performance, eliminating driver and tweeter "artifacts" for more realistic sound reproduction at high and low volume levels.

    • 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.
    • 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.

    Woofers: Each speaker features a 5" (12.7cm) long-throw mineral-filled polypropylene cone driver for clean midrange and deep, accurate bass. For a smoother response and improved durability, each woofer uses a butyl rubber surround.

    Tweeters: Each speaker features a 3/4" (19mm) anodized aluminum dome tweeter with rubber surround and neodymium magnet for better power handling and smoother response.

    Enclosure Design

    Rugged Enclosure Design: The durable, mineral-filled polypropylene cabinet design, with molded-in bracing, sounds like a real speaker (not "an outdoor speaker"), and survives years of seasonal changes, for great sound, no matter what the weather. The rugged, mineral-filled polypropylene enclosure features a rustproof aluminum grille, rustproof aluminum bracket, and stainless steel/brass hardware.

    Note: The speakers are available in a black or white finish. The enclosure is also paintable.

    Broad Coverage Baffle Design: The sculpted front, steeply-angled baffle design and rounded enclosure minimize diffraction (sound reflecting off of hard edges) for more open and lifelike imaging.


    5-way Binding Posts: The Atrium 5 has a pair of gold-plated binding posts that will accept bare wire, pin connectors, spade connectors, single- and dual banana plugs.

    Mounting Options

    Speed-Locking Mounting System: The included rustproof aluminum brackets allow multiple mounting options and are quick-and-easy to install. The Atrium 5 can be mounted either horizontally or vertically and aimed to deliver the best possible sound in a variety of situations The integrated brackets provide full 180-degree rotation (when mounted vertically or horizontally. The mounting brackets even allow the speaker to be mounted snugly in a corner or under an eve (at a downward 45-degree angle). You can remove the bracket and use the speaker's built-in stability feet, if you simply want to place the speaker on a table or shelf.
