Polk AudioAtrium 4 Outdoor Speakers with Powerful Bass (Pair, White), All-Weather Durability, Broad Sound Coverage, 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!** 🎶🔥

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. It will give you the best performance in terms of power, loudness, clarity. I paired these with a Fosi V3 amplifier. A good inexpensive way to outfit your outdoor sound system.

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 will add myself to the chorus of praise for these speakers though I admit I was somewhat skeptical going in. Speakers come in ranges of sound quality and pure quality alone is not the sole criteria when you are dealing with outdoor speakers that might have to perform at a party and still be heard, undistorted and filling without being overpowering. That is what I hoped for and that is what was delivered with these speakers. Do they approach the sound quality of my main system? Of course not. My main system is for critical listening and these are for projecting sound in an unfriendly environment potentially with a lot of background noise. That they do that in spades. With a deck full of people these speakers cut through and projected music without being overwhelming and presenting lots of detail and most importantly the essence of the music. I could not ask for better outdoor speakers at this price point.

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.

Excellent!I have a pair of Atrium 4’s that have performed admirably for over ten years! Those were purchased and deployed pool-side at our former home. Like them so much that I took them with me to our new place.Upon moving our pool/patio area size increased substantially. The 4’s were still part of my overall plan but I wanted to increase coverage and my speaker count to four and thought a next size speaker up with a bit more bass might be in order.Over time, I ordered/tried two other, popular and well rated outdoor speakers to fit the desired need and for various reasons returned both. Quite frankly, neither sounded any better than my old 4’s. Both cost more.I then ordered some Prime Days, “used-like new” 5’s for a fantastic price ($148) and am delighted that I did😁 Third time/try was indeed the charm! Not only do they fill the space with quality/balanced tone, I now know that my outdoor sound 🎶 needs are more than satisfied for many dependable years to come!There’s a reason that this Atrium series from Polk has been the outdoor standard setter for over a decade, I should have never wandered/doubted. Lesson learned.

So glad I purchased these. Sound great in my backyard. Easy to install. White isn’t super bright so it blends in nicely. Far superior than the previous black speakers (not sure of brand) we had in terms of sound quality and aesthetic. Recommend the Atrium 6 vs Atrium 5 since these have bass ports for richer sound.
