Polk Outdoor Atrium 4 Speakers

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 !

Atrium 4 outdoor speakers

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.

Speakers Sound Great and Look Great

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.

Outdoor speakers that don't like the outdoors!

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!

Ditch your old outdoor speakers for a pair of Polk Atrium 4's!

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!!

Excellent outdoor speakers

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.

Good for the price

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

Pretty To Look At, Average Fidelity

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.

Well built speakers

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.

Great little speakers!

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.

Outstanding Sound

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.

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...
