Atrium 4 Outdoor Speakers, Powerful Bass (Pair, Black) | Full-Range Audio, 4.5" Polymer Cone, All-Weather Durability - Marine & Pool Compatible, Easy Speed-Lock Mounting System

I bought a **pair of Polk Audio Atrium 8 SDI speakers** for my **back patio expansion**, and they have been **nothing short of incredible**! The **beautiful design** blends seamlessly with my outdoor space, and they are built to withstand the elements.I paired these with a **SunFire amp**, and the **sound quality is simply awesome**—rich, clear, and powerful, even in an open outdoor environment. Mounting was **easy**, and the build quality feels **top-notch**, exactly what I expect from Polk Audio.I’ve been a **Polk Audio fan for almost 40 years**, and their **reputation for quality and durability** is well-earned. I still have an **older set in my garage that’s over 20 years old**, and they still sound fantastic—**which is exactly why I chose Polk again**!If you're looking for **high-quality outdoor speakers** that will last, these are a no-brainer. **Highly recommend!** 🎶🔥

Speakers appear well made. I have only been using them for a short time, so long term durability is somethingI cannot comment on. However, for a compact speaker they sound great and put out a surprising amount of bass.I was able to drive them quite loud without break up or distortion. I also like that they are 8 ohms which makes thempretty standard and compatible with virtually any amplifier.

I purchased these as replacements for outdoor speakers that were installed on a new-to-us house, but that were no longer working. I bought the white version, and they compliment our home's exterior trim color nicely. Installation was a breeze -- each speaker is bolted to the house with two wood bolts, then attach the wire, and that's all there is to it.In my case, I am using a dedicated "left" and "right" speaker setup, so I cannot address how well these work when they are wired with both left and right speaker wires. I can say that you need to slide the switch/contact cover over on the back of the speaker if you are wiring them as "left" or "right" like you would for normal speakers, or else the sound is quite a bit softer. This makes more sense when you look at the unit itself--but there are two ways to wire each speaker, so follow the directions for your application and you'll be fine.As you'd expect, there is not a ton of bass to these speakers, however when connected to a home-owner quality sound system (Sony), they sound quite good as an external speaker, and better than ones that we had at our previous house.I'm hopeful that I can get at least 5 solid years out of these speakers in order to justify the price. We'll see how that works out, but I think Polk quality is quite good for my purposes, and I have confidence that it has been money well spent.

The media could not be loaded. Very good speakers for the price. My application of these speakers was in my garage where I paired them with a Fosi V3 amplifier. Great clear sound and respectable base. They can play loud without distorting. They appear to be well made and are easy to setup. Very good overall performance with a good return for your dollar. Recommended.2-8-25Still think I made a good decision to buy this speaker. I do recommend that you buy the 48 volt power supply If you buy the Fosi V3 amp. It will give you the best performance in terms of power, loudness, clarity. I paired these great speakers with the Fosi V3 amplifier. A good inexpensive way to outfit your outdoor sound system.

I got these as well as a pair of Atrium 5s to compare. I set both pair up with my indoor McIntosh Pre and Amp and auditioned them for a few hours. The bass on the 5s had a sort of artificial sound lacking definition. The 6s sounded really solid and reasonably flat with the Tone controls bypassed on the pre-amp. I liked the compact size of the 5s and they would have been easier to mount under the eaves on my deck to replace some worn out Mirage speakers I had that sounded great. But I was worried about the bass.The 6s are much heavier and larger and more expensive. But I think they are worth it. Once I got them installed and played a set of tunes I use for setting up speakers (Fagen / The Night Fly, etc), the reinforced bass, with them now much closer to the wall than they were inside, was a lot. Now connected to a nice Marantz Pre and Amp, I may need to cut the bass and treble 2-3db to get a flatter response.The A6 can cover a large area and deliver plenty of bass. I don't like over the top bass and prefer a flatter audiophile EQ, and these do that easily. I think the A5s may have worked, but the character of the bass sounded odd, so I never mounted them outside to try. Even reinforced by the wall, I don't think I would have liked them as much.Beyond that, they were fairly easy to mount - the brackets have notched detents, so they don't spin freely, which is nice - my old Mirages used to sag after a while.Overall, the sound seems mid-range weak, bright, and a little bassy. My old Mirage speakers sounded better, but they are no longer made. That said, I think I can dial them in pretty well with the treble and bass controls on the pre-amp.

The sound from these almost made me cry. It has all the deep bass tones and the highs are crisp and clear. They were easy to install outside and given that I was on a second story ladder to do it, I was grateful for the way they designed the easy clip in and then tighten set up with the mounts. I highly recommend these bad boys, you will not be sorry!

I previously had the Polk Patio 200’s which are a twin to the Atrium 5’s. Thought they kicked s for outdoor music and still do. Then I stepped up to the Atrium 8’s and wow just another audio dimension added. Power, spaciousness, and sound went up, up, up. Excellent speakers for backyards, patios, or anywhere outside because they can handle any type of weather thrown at them. Place them near the corners and bass is solid. So happy I upped my backyard tune source.
