Easy to install outdoors. The sound is very good. We bought 2 sets and have great sound out by the pool.

Excellent Speaker, best bang for your buck. I have multiple sets outside that have been exposed to the elements year round for many years. One pair is 10 years old and still sound great !

Great sound and lasts a very long time in the Florida outdoor environment. Bought these to replace one of our 10 (ish) year old atrium 45. Still using 3 of the Atrium 45?s. Now I have a spare if I have future problems. Love the atrium 4 as well.

Fantastic! We have a small 1300 sq ft cafe, and with just one pair of Polk speakers we have music throughout the space. We got the white ones, and with our very light green/blue walls, they just blend right in.

I bought a pair of these to finish off our garden patio project around 9 months ago. After bringing them inside for winter last week, I was shocked to find one full of water already! To be honest, I can't say I was overly thrilled. The water inside the cabinet must have been about an inch deep!

I have a previous pair so I knew the quality was good. Price was a great deal and shipping was fast.

I replaced a pair of outdoor Bose speakers with these and what a difference! Instead of bass heavy and highly compressed sound, you get a nice full spectrum of sound, and still with good bass. Great overall tone from the speakers and good looking too. Easy to set up and given the holiday pricing, best value purchase I've made in a long time!!

I have several Polk speakers throughout the house and these continue in the tradition of not disappointing. Mind you, I'm no audiophile, but I do enjoy music. The install was simple and they put out a nice balanced sound that can get quite loud (if wanted). They put out enough bass to make me feel like an outdoor sub would be extravagant. Vocals were clear. Overall, I'm very pleased with my purchase and would certainly recommend.

It was easy to install these attractive outdoor speakers and the sound quality is descent. Worth the price especially with a rebate. Didn't give it 5* because I can't speak to the how they will hold up to the outdoor elements

Looks and sounds great. Haven't had them long enough to know how long they will last. Hopefully get Years out of it.

I have used some different speaker, but impressed by the smaller size and the sound quality.

I have other Polk speakers and these seem to follow suit in somewhat muddy midrange response. Still, they are attractive and well-constructed, worth the price with a rebate.

Awesome Polk sound. I have an indoor surround sound that added the perfect touch.

I've had a set of the atrium 45 speakers for a few years and have been satisfied with them. These atrium 4 speakers appear to be the current version since they appear and sound quite similar. I was using my first pair as rear surrounds and they sounded and worked good - however I'm moving them outside - which was my original intent. Don't expect any bass from these and if you boost the bass frequency to raise it, these will distort and eventually fail. A nice sounding little speaker with great flexibility and worth buying when on special.

This was a great purchase for us to get some extra sound in the second zone of our place. While I'm no audiophile, they sound great.

I tested these out over the weekend after installing them on Saturday. I decided to place them underneath a patio cover in my backyard. They were place approx 18' apart. I have the pair hooked up to the ZONE 2 option on my Denon receiver. The mids and highs came through beautifully while the bass was just slightly lacking but was still very smooth. Full soundstage and you can crank these pretty loud without distortion. I played anything from hard rock, to country, to R&B and everything sounded great. Minus 1 star because I can't attest to the weather-proofing as of yet but they are outdoor rated. Very happy with the value of these speakers and highly recommend to anyone who is not an audiophile.

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.

2nd pair of Polk Atrium speakers I have owned - both pair have filled up with water, Not water tight!

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.

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.

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 e...

Great speakers
By Tom M.
Great speakers and a great price, I recommend these speakers
An acoustic marvel in a compact form, the Atrium 4 All-Weather Outdoor Loudspeaker from Polk Audio delivers exceptional sound fidelity that belies its size. Designed for versatile placement, this stylish and efficient pair of speakers is perfect for spaces where traditional speakers might not fit, such as by the pool, in the kitchen, or discreetly in the family den. With the ability to fill your backyard or any outdoor setting with rich, full-range sound, the Atrium 4 stands out as a reliable choice for those who appreciate high-quality audio in every corner of their living space.
Crafted with a 4 1/2-inch (11.43cm) long-throw mineral-filled polypropylene cone driver, complemented by a butyl rubber surround, the Atrium 4 produces a surprisingly robust bass response from its compact design. The high frequencies are handled with finesse by a 3/4-inch (19mm) anodized aluminum dome tweeter, featuring a neodymium magnet for improved power handling and smoother response across the audio spectrum.
The broad coverage baffle design, a refined iteration from Polk's renowned Atrium series, ensures that these speakers deliver wide dispersion of critical mid and high frequencies, creating an immersive listening experience even in large open spaces. This design not only maximizes sound coverage but also maintains the intricate details of your favorite tracks.
Durability is a hallmark of the Atrium 4, with all-weather certification that surpasses rigorous 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). This certification guarantees that the Atrium 4 speakers can effortlessly endure extreme temperatures, heavy rains, and other challenging weather conditions, making them an ideal choice for both outdoor and high-moisture indoor environments.
Installation is a breeze with the Speed-Lock mounting system, allowing for easy, safe, and one-handed installations, even in the most challenging locations. The simplified mounting process minimizes the hassle, ensuring a secure and precise placement of the speakers.
The Atrium 4's cabinet is constructed from a durable, mineral-filled polypropylene, with molded-in bracing that not only withstands seasonal changes but also delivers sound quality comparable to indoor speakers. Polk's patented Dynamic Balance and Klippel optimization technologies are employed to ensure flawless material performance, eliminating any driver and tweeter "artifacts" for the most authentic sound reproduction at any volume level.
Finished with rust-resistant aluminum grilles and brackets, and featuring stainless steel and brass hardware, the Atrium 4 promises longevity with no risk of rust. Connectivity is made reliable with gold-plated 5-way binding posts, ensuring secure and dependable hookups.
Available in weatherproof black or white paintable finishes, the Atrium 4 All-Weather Outdoor Loudspeaker is not just a speaker - it's a statement of style and a testament to Polk Audio's commitment to sound excellence. Whether you're looking to enhance your outdoor entertainment or seeking a refined audio solution for indoor spaces, the Atrium 4 is engineered to impress.
