Product Details

Polk Audio Atrium 4 All Weather Outdoor Black Loudspeaker - ATRIUM4BLK (Sold As Pair)

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 Atrium 4 meets our newly established weatherproof standards, nor does it compromise on sonic performance. The Atrium 4's high quality driver and tweeter deliver an impressively big sound from a very small package. Yet its compact size makes it ideal for tight, out-of-way installations. By the pool, around the kitchen, tucked away in the family den or filling the backyard with great sound. Like our bigger Atriums, the Atrium4 is built rugged to deliver years of great performance fall, winter, spring and summer.

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.

  • 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. Click here for a technical explanation.

Features:

  • 4 1/2" (11.43cm) long-throw mineral-filled polypropylene cone driver with butyl rubber surround pumps out surprising bass response from a compact design.
  • 3/4" (19mm) anodized aluminum dome tweeter with rubber surround and neodymium magnet for better power handling and smoother response.
  • Broad coverage baffle design, adapted and applied from our current Atrium design but with subtle improvements in the new Atrium Series. You want to fill a large open outdoor space with big, full-range sound, The new Atrium Series has a more steeply-angled baffle design that maximizes critical mid- and high-frequency dispersion over a large area, without sacrificing the detail.
  • 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 worst Mother Nature can dish out, whether its extreme temps or heavy rains. With Certification like this, your kitchen or bathroom installation is a cakewalk for Polk Audio All-Weather speakers.
  • 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 truly great sound, no matter what the weather.
  • 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.
  • Aluminum grilles and bracket, with stainless steel and brass hardware: No rust. Ever.
  • Gold-plated 5-way binding posts for the most secure, dependable hookups.
  • Available in durable, weatherproof black or white paintable finishes.

    I purchased these to be the used as outdoor speakers around the fire pit at my cabin. They were perfect for this application as I didn't want to spend a lot of money and provided decent sound quality.

    Outstanding Sound

    By 

    from Norfolk, VA, United States

    Comments about Polk Audio Atrium 4 Outdoor Black Loudspeakers:

    I bought one pair of these to replace some worn out Mirage speakers and I liked them so much I bought a second pair. We have them on our deck out back and the sound really does rival good indoor speakers. My wife loves their small size and looks and we both love the sound. Their off axis response is excellent, making placement much easier. If you need more bass, just pair them with an outdoor sub like I have. An excellent value.

        Theses speakers live up to Polk standards that I know. The sound is great they blended in to my house. Worth the money.

        Service and delivery comments:

        I live in the Chicagoland area they ups these to me. Ordered them on a Tuesday had them next day. Free shipping. Well worth it not to drive the hour up there to grab them. ABT had the best price on these by far.

        Was concerned that the low end wouldn't be enough, but after installing them I was very pleased. I have them out on my deck, which is a very open space, and they provide full, rich sound! I also have a gazeebo out in the yard and the sound easily reach to it.

        Comments about Polk Audio Atrium 4 Outdoor Black Loudspeakers:

        These are great if you're looking for smaller size outdoor speakers, which is the main reason I got them. The sound is clear and has a nice lower end and higher end as well. They can reproduce realistic sounds of saxophones and drums (Jazz fan). They should last long as expected.

        Just installed an Atrium 4 speaker set and I must say I'm pretty amazed! Good sound, especially for my purpose, upgrading my porch with music, not to be played at party levels. I really am curious how the Atrium 5-up sound! - the Atrium 4 is already awesome.

        Comments about Polk Audio Atrium 4 Outdoor Black Loudspeakers:

        I bought two pair of these to put below decks in our sailboat. I figured being outdoor speakers, they would work well and I would not have to worry about them while the boat was out of the water in the winter months. Installed them this past weekend and we are very happy with them. The boat's stereo system has Bluetooth so we could watch a movie on my laptop and play the audio over the stereo. The sound was incredible, much better than even our home theatre system. Speakers are compact and easily placed, which is a big plus with the limited room in a boat.

        Comments about Polk Audio Atrium 4 Outdoor Black Loudspeakers:

        I got the atrium 4's a couple weeks ago, they have amazing sound compatible to bose witch was great considering the price difference and I assure you I have already tested the durability of them... 2 days after mounting them on my back porch we had a severe thunderstorm that produced golf ball size hail! I personally watched these speakers take multiple hits from this hail, after the storm had passed I turned them on to see if they still worked and sure enough they sounded just fine and not even a scratch or dent! Great job polk! I would recommend these to anyone.
