Our take on the Polk Audio Atrium8 SDI

by Tara W.
Polk Audio

Outdoor speakers let you move the party outside

Outdoor speakers are built tough -- they laugh at wind, rain and weather. Tuck a pair under your eaves and they'll pump out the tunes to keep everybody smiling and swaying at your next cookout or pool party. We also have some "rock" speakers that blend seamlessly into your landscaped lawn or garden.

Use Polk's Atrium8 SDI speaker when you need maximum flexibility along with premium outdoor sound. It can stand alone as a single stereo speaker, or you can put two together for a high-performance stereo pair. One speaker is convenient when you want to pump tunes to a smaller area, like a deck or patio, or when mounting options are limited. If you have room for two speakers, these speakers will give you fuller sound and better stereo separation in larger listening areas. A simple switch allows you to choose between single-speaker or traditional two-speaker stereo playback.

This speaker boasts the build quality you'd expect from Polk. It gives you superb audio performance, thanks to dual 1" tweeters, one 6-1/2" woofer, and PowerPort® bass venting. And the rugged, weatherproof design meets or exceeds stringent military specifications for full exposure to the elements. That means you'll enjoy years of great tunes, whether you install them in your bathroom or in your backyard.

Polk's new Speed-Lock™ system makes mounting the Atrium8 SDIs quick and easy. Install the bracket and simply click the speaker into place. Then just aim the sound towards your listening area and tighten down the included thumbscrew.

    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.

    6.5" DVC Woofer: The Polk Audio Atrium8SDI uses a dual-voice coil long-throw aerated polypropylene 6.5" woofer for clean midrange and deep, accurate bass. The dual voice coil design adds greater efficiency and power handling. For a smoother response and improved durability, the woofer uses a butyl rubber surround.

    Dual Tweeters: The Polk Audio Atrium8SDI has two 1" anodized aluminum dome tweeters with rubber surrounds and neodymium magnets for better power handling, smoother response and greater accuracy. This Dual Tweeter Array features Stereo Tweeter Aiming for excellent imaging, allowing you to use the Atrium8SDI as a single stereo speaker, or as half of a stereo pair.

    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.

    Connections

    Dual Input/Single Input Feature: A rear mounted switch allows the Atrium8SDI to operate as a single, dual-input speaker for stereo applications, or a traditional single-input speaker for left or right use. When using the Atrium8SDI as a single stereo speaker, the dual tweeters and dual voice coils handle the left and right signals independently.

    5-Way Binding Posts: The Atrium8SDI has two sets of gold-plated 5-way binding posts that will accept bare wire, pin connectors, spade connectors, and banana plugs (single or dual).

    Mounting Options

    Speed-Locking Mounting System: The included rustproof aluminum bracket allows multiple mounting options and is quick-and-easy to install. The Atrium8SDI can be mounted either horizontally or vertically and aimed to deliver the best possible sound in a variety of situations The integrated bracket provides full 180-degree rotation (when mounted vertically or horizontally. The mounting bracket even allows 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.

    Love the Atrium 8 speakers. We bought these to use for our daughters wedding. We had the wedding on our lake lot and we were worried that the sound would be lost due to the size of the outdoor area. The speakers were awesome. Such great surround that you couldn't tell where to music was coming from. I would highly recommend.
    Pros:
    Great sound for large out door area's.
    Cons:
    Non

    Atrium 8 SDI WH

    Written By JohnG, Baltimore, MD on Friday, February 03, 2012
    Crutchfield Customer Review (What's this?)
     
    I have several Polk Audio speakers (7.1 home theatre in-wall with powered 10 inch subs and a couple of auxiliary LC80FX in ceiling speakers). I've never gone wrong with Polk and so far this speaker is no exception. The audio quality is excellent. I think the biggest factor in my overall satisfaction will be whether or not it holds up well to the elements, though, and it's too early to say.
    Pros:
    Great sound. Versatile (can be used as a single unit with two sets of drivers receiving signals from two sides of a stereo output, or as one of a set of multiple speakers in a conventional setup). Substantial mounting hardware that is user friendly.
    Cons:
    Fairly heavy. Fairly expensive.

    purchased this for my backyard where my patio and pool is. This speaker is extremely powerful. Sounds clear, looks great, so glad I purchased this item. I put it under my eaves and added the niles weatherproof volume control from crutchfield. The volume control is a must have with this product. Awesome.
