Polk Audio Atrium 4 Outdoor Speakers - Black
Atrium Series Outdoor Loudspeakers offer the ultimate in flexibility reliability and high fidelity sound quality for all your outdoor spaces. They give you the freedom to put speakers anywhere you want high performance sound. Sure there are lots of "outdoor" speakers out there. But look at the fine print. Many of them are suitable only for placement in sheltered locations. Atriums are true four season loudspeakers. Polks Atrium Series speakers meet or exceed military specifications for environmental endurance. The tests have coded names like "ASTM D5894-UV Salt Fog" "Mil standard 810 Immersion" and "Mil standard 883 Method 1009 8 for salt and corrosion." But passing them means that Atrium speakers can withstand some of the worst that Mother Nature can dish out. In addition stainless steel brass and aluminum hardware ensures years of rustproof reliability.

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.

Easy and convenient mounting system. Sound quality is exceptional. Took them in for winter and within seconds was up and running again in spring. Sound is fantastic. Mounting allows you easily to change angle and sound distribution in seconds in case you want to focus on different parts of the backyard/porch/etc. I'm writing this review because I'm looking to buy a 2nd pair for inside my Pool Cabana and am shocked at the awesome price compared to those single smart speakers (which is fantastic in my office at work which i hope i'll see soon). And since the voice control is a "nice to have", i'll add a second pair rather than spending hundreds more since i already have a Onkyo network ready receiver in my Cabana.

Installation was easy. The mounting bracket gave several options for mounting including in the corner where the wall and ceiling meet. The speaker kind of “snaps” into the bracket and holds temporarily so you can attach the screws. I have them installed in the garage for some background music while I wash the cars or do some other work. They are replacing some in-ceiling speakers that were part of an integrated whole home audio that gave up on me. I figured a outdoor speaker would be a better choice than the in ceiling speakers even though it’s in the garage. Don’t expect to have a dance party or do any critical listening with these but if your looking for some background audio for an outdoor application then these are a good value IMO.

Great speakers. They were on sale and worth every penny even at full cost. Doesn’t distort and very clear tweeters. Def look at these as opposed to higher price speakers.
These speakers sound great, look great, are easy to install and can handle ANY weather. Noticed a few reviewers mentioning brining these speakers in for the winter, which I did as well when I first got them. That said, I have now owned mine for somewhere between 6-8 years and have left them outside through Winnipeg winters for the last 3 of those years. They are attached to the privacy wall of my deck and have no covering on them. They still look and function the same as the day I bought them. Expensive? Yes. Will you ever need to buy another pair? No. Worth every penny.
Just remodeled our patio and upgraded our outdoor experience with these speakers. Nice sound for a smaller speaker. Bass is adequate for our patio area but if your preference something with more bass consider a speaker with a bigger woofer. Perfect for our 20' x 20' area. Seems to be a very efficient speaker.
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!
Well. Just got these. Ran cables out to my back yard. A little longer than they say is good. 90 ft. . However Speakers sound great. They sound way better loud. Enough bass for the size. At low volumes they fill the space but need some bass. Depends on what music you listen too and also for outside they kick regardless. Not sure about the comments that loud is not good. It’s definitely better. Great deal for price at 139 cdn. . I don’t think you can go wrong. I have had a polk audio 12” Sub for 18 yrs. kicks the house.
I have lots of different equipment from low end to high end. So setting up a system for the back yard meant getting decent speakers at a decent price. These were on sale so I was able to get two sets and that was a great bonus as I didn't have to get cheapo speakers instead. Very nice detailed sound. If you mount in a soffit the sound is better as they use the building to enhance the sound. Only complaint is that the rear binding posts can't accept standard banana plugs. but are designed really for bare wire or spade connection.
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.
