Our take on the Polk Audio Atrium8 SDI

Use Polk's Atrium8 SDI speaker when you need maximum flexibility along with premium outdoor sound. It can stand alone as a single stereo speaker, or you can put two together for a high-performance stereo pair. One speaker is convenient when you want to pump tunes to a smaller area, like a deck or patio, or when mounting options are limited. If you have room for two speakers, these speakers will give you fuller sound and better stereo separation in larger listening areas. A simple switch allows you to choose between single-speaker or traditional two-speaker stereo playback.

This speaker boasts the build quality you'd expect from Polk. It gives you superb audio performance, thanks to dual 1" tweeters, one 6-1/2" woofer, and PowerPort® bass venting. And the rugged, weatherproof design meets or exceeds stringent military specifications for full exposure to the elements. That means you'll enjoy years of great tunes, whether you install them in your bathroom or in your backyard.

Polk's new Speed-Lock™ system makes mounting the Atrium8 SDIs quick and easy. Install the bracket and simply click the speaker into place. Then just aim the sound towards your listening area and tighten down the included thumbscrew.

Awesome speakers. This is my second set and I coupled them with the Atrium Sub. Family and neighbors with other brands of outdoor speakers are envious of my setup.

    Crutchfield Customer Review (What's this?)

    Ordered to use on my deck where space was an issue for separate left & right speakers. I like that I can use SDI for a standalone speaker but have the option to use it as a left/right channel in the future if I ever want to add on. I'm using a Sonos Connect Amp to power and the sound is impressive for a single unit that's weatherproof. Installation was easy and the speaker and bracket both appear to be high-quality. I would purchase again.

    Pros: SDI


    Outstanding outdoor speakers

    Awesome speaker

    Chris from Clemmons, NC on 4/17/2017

    Crutchfield Customer Review (What's this?)

    Bought these because I had them in house I just sold, awesome speakers, plenty of bass, didn't need a sub

    Pros: Good bass . Luv em

    Cons: None, there's a reason I bought them for my new house

    Quality sound

    Outdoor Rocker from Rocklin, CA on 11/16/2016

    Crutchfield Customer Review (What's this?)

    Replaced an older pair of "rattle boxes" with these. What a massive improvement! Love the way these brackets work, very secure and allows you to dial in the angle after mounting. Highs are incredible on these. Indoor setup is bass heavy and the sound out of these is not quite there, needed to boost those frequencies to these speakers. May add subwoofer outside, but for now glad we went with these larger Polks with the 6.5" driver.

    Pros: Sturdy brackets offer security and flexibility


    Great sound

    Sturdy T from Dublin, NH on 10/2/2016

    Crutchfield Customer Review (What's this?)

    Expecting to have to compromise on sound with speakers for outdoors. Absolutely no compromise with these, they sound great and can take the volume up. We joke that if we aren't careful we'll curdle the neighbor's cow's milk. Really awesome sound.

    Pros: Great sound

    Cons: Large speakers.

    I love the quality of these speakers. They reproduce great sound and were perfect my outdoor porch area.

    Pros: Easy to install even for one person.

    Cons: They were a little bit larger then I originally expected.

    Crutchfield Customer Review (What's this?)

    These speakers sound absolutely amazing. Pushing them with a HK 240 Watt rms system. Paired with an infinity 12" sub who needs a live band?

    Pros: Exceptional

    Cons: Can't think of any in my case.

    Great outoodoor speaker PAIR

    Matt from Hillsborough, NC on 7/24/2016

    Crutchfield Customer Review (What's this?)

    I ordered a single speaker for the back porch and it sounded okay in SDI mode but really just okay. This is probably true of any speaker, but a pair just sounds a lot better. Grabbed a second speaker while still on sale and they are great. The second speaker made all of the difference. Sounds good on the porch at low volume or I can crank it up for clear sound well out into the yard. I am satisfied with the bass response for the music that I listen to (mostly rock) and I do not intend to add a sub. I am driving a single stereo pair of these speakers on a Sonos Connect:Amp and it will push them un-godly loud. I could certainly add another pair elsewhere if desired on that amp.

    Pros: Loud, clear and powerful enough to fill a large open space with sound. Well worth the $$ for this reason in particular. A smaller pair would be fine on the porch but would not push sound as far out in the yard.

    Cons: Not very impressive in SDI mode. Could possibly get me in trouble with the neighbors.

    Polk is a hit!

    Alex from Park Falls, WI on 7/22/2016

    Crutchfield Customer Review (What's this?)

    These speakers work well with an outdoor theater system. They sound great and have a good mix of bass and tweeter. Easy to hook up, and install. The easy one hand secure top and bottom, make install easy and secure.

    Pros: Secures easy, great sound. Waterproof, and

    Cons: Really no Cons!!!!!!!

    Love them!!

    Scott from Westminster, MD on 7/20/2016

    Crutchfield Customer Review (What's this?)

    My Boston outdoor speakers finally died after 11 years of faithful service. I went to Crutchfield to see what was out there and found these on sale. Read the reviews and decided to pull the trigger. Installation was certainly easy enough. Delivery was next day. They sound great out on my deck. Decent bass. Great mid and high range sound. And the sound travels well to the entire yard

    Pros: Great shipping. Good price for outdoor speakers. Expandable. Easy Install

    Cons: I wish the bass were a little crisper, but that's hard to accomplish outdoors at this price point.

    Pros: GOOD SOUND


    Polk Audio Atrium8 outdoor speakers

    Krislu from Huntington,NY on 7/14/2016

    Crutchfield Customer Review (What's this?)

    I bought the Atrium 8 for my backyard/pool area. When I opened the box I was surprised at how big and heavy this speaker is. I soon realized it is a high quality and very well made speaker. The sound the Atrium8 produces is crisp and clear and awesome. Catching this speaker on sale is the cherry on top! When this speaker goes on sale everyone should be buying!

    Pros: Great sound! Excellent quality, strong mounting bracket, excellent quality connectors, nice looking, easy installation

    Cons: None

    Palmer S from Charlotte, NC on 7/11/2016

    Crutchfield Customer Review (What's this?)

    These speakers are much bigger and heavier than I anticipated, but man do they sound great. I installed these on my patio and really enjoy sitting out there and listening to these great speakers. A definite buy.

    Pros: Excellent build quality and sound great.

    Cons: None

    Sounds great right out of the box!

    JT from Maysville , KY on 7/10/2016

    I bought these on sale, which is rare, and they rock! These are used for an outdoor pool deck. I paired these with a Crown XLS1000 Power amp @ 215W per channel and a Polk Omni P1 wireless adapter. It's a completely invisible and wireless stand alone system that kicks butt! The sound quality is superb. If your up in the air on buying these don't wait. Get them now while they are on sale! Put some good clean power to them and you will be pleased. I can't wait till mine break in, they will only get better!

    Pros: Sound quality, ease of mounting, mounting bracket super sturdy, solid construction

    Cons: None for me, some say they are bulky but I wouldn't concern yourself with that. They are very well built!

    Great sound, great quality

    3Pete from Camano Island, WA on 6/13/2016

    Crutchfield Customer Review (What's this?)

    I've always been a fan of Polk Audio products and this speaker does not disappoint. It's mounted up under the roof eave near my garage so it's technically outdoors but still weather protected. The mounting bracket provides for 45-degree mounts in corner locations which worked perfectly for me. The speaker is heavier and larger than I expected but the full, rich sound coming out of it explains that. Another great feature that works great for me is the option to run both channels to a single speaker. I don't understand the electronics providing for this (bi-amping?) but I can tell you the result is awesome. Look forward to many years of great sound coming out of this speaker.

    Pros: Sturdy mounting bracket, great quality connectors, impressive bass.

    Cons: Larger than I expected but worth it.

    Simply Awesome

    Sound-dude from Islip, NY on 6/13/2016

    Crutchfield Customer Review (What's this?)

    This is the 3rd set of speakers I have been through for my backyard and these are simply spectacular! Great sound and bass with easy install and adjustments.

    Pros: Easy install and excellent sound quality

    Cons: Slightly larger than I expected

    Great Outdoor speaker value

    Chuck from Mechanicsville, VA on 5/31/2016

    Crutchfield Customer Review (What's this?)

    I bought this speaker because it has the capability of running both channels (Right and left) into one speaker. I could do two speakers on my patio, but figured I would try the one speaker and see how that worked and always add another if I needed to. The single speaker sounds great and is plenty loud. We have a very large patio and outdoor kitchen and this one speaker puts out enough for me. It was really easy to install, since the bracket comes off and then you install the speaker later. I am very pleased!

    Pros: Can combine channels, so you only need one speaker


    Polk Atrium 8 - Sound Great

    Eric W from Livermore, CA on 10/28/2015

    Crutchfield Customer Review (What's this?)

    I previously bought another brand of outdoor speakers and I just was never 100% satisfied. I should have bought these Atrium8 speakers in the first place, but I went against my better judgment. Even though these are designed to be outdoor, I take them down every time I get done using them. You just can't beat the construction of the Polks. They are solid and when you slide them in place, you almost don't even need to screw down the end caps (and I have these horizontally mounted. The sound also is awesome. I use them for my backyard home theatre and I love them. The only thing that I wish was better is if they made a dedicated outdoor center channel with two drivers instead of one. Other then that, I am completely satisfied.

    Pros: Great Construction and Mounting. Great sound.

    Cons: Nothing really, I love them.

    Polk outdoor speaker

    Jerry, Vermont from Vermont on 9/1/2015

    Crutchfield Customer Review (What's this?)

    The speaker was hefty, well built, easy to install and we are very pleased with the sound. It cranks up to all the decibels I would want for our deck area, but has enough reserve to disturb wildlife.

    Pros: Good quality, good value, even though cheaper options exist.

    Cons: A bit heavy, easier to have someone helping install overhead.

    Great product

    John from South Milwaukee, WI on 8/16/2015

    Crutchfield Customer Review (What's this?)

    Sounds great, easy to install and construction feels solid.

    Pros: Sound quality is very good and they were very easy to mount. The binding posts seem to be very sturdy, excellent quality. Using two on our deck connected to zone 2 of a Yamaha RX-V679.

    Cons: They are surprisingly large but I suppose had I paid more attention to the products description I would have realized this.

    Like so Much I Bought a New Pair

    Mark W. from New Jersey on 7/6/2015

    Crutchfield Customer Review (What's this?)

    I owned a pair of the much older Polk 65 sdi and after at least 15 seasons of Boston, Connecticut and New Jersey weather (yes they survived Hurricane Sandy) I wanted to upgrade and since I needed the 4 input in the back for speakers I had no choice but to upgrade with the new 8 series. I have this paired with a 12 channel Niles amplifier that drives my Sonos system in 7 different locations. The speakers are fantastic and have really nice lows accompanied with great midrange and highs. They make all my other outdoor speakers sound muffled so I expect to replace more speakers this summer with additional 8 SDI's. You will be really happy that you got these but make sure you a nice clean amp so you will get the crisp tight bass that you rarely get with any outdoor type speaker.

    Pros: Bass, clean crisp sound

    Cons: I have neighbors......

    Polk Atrium 8

    JeffS from Loves Park, Illinois on 7/6/2015

    Crutchfield Customer Review (What's this?)

    Used two of these speakers in an outdoor bar setting for a buisness. The speakers are very easy to install. I thought about using four but actually two work very well. Great coverage! The sound is very clear and the bass when adjusted correctly gives great sound also. I used a Crown amp to power them. If need be I can get the model of the amp. But overall getting nice compliments from the patrons compared to the older MTX speakers that were taken out.

    Pros: Very well designed! Great sound! Easy to install and sturdy! Not a gripe but they can handle some power so get a good amp to run them.

    Cons: None

    Solid speaker

    DavidB from Michigan on 7/5/2015

    Crutchfield Customer Review (What's this?)

    This is the third such speaker that I have purchased so you can tell I do like them. They are a solid speaker with a modern look. I have installed two in my pool area and one in my backyard. Nice clear sound and nice wire connections that assure of a continued connection in all weather.

    Pros: Nice sound and good looks

    Cons: bigger than anticipated

    Great Sound

    Atrium8 - Impressive Speakers

    TJD from Albany, New York on 6/9/2015

    Crutchfield Customer Review (What's this?)

    The Atrium8 SDI speakers are the first Polk product I have ever purchased and are quite impressive. They are paired with a new Harman Kardon HK3770 receiver. Speakers are mounted approximately 10' high and 20' apart and they really fill a very large yard with great sound. Installation is easy and product construction is very solid. We have pumped a wide range of music through them, from Norah Jones to Rage Against the Machine and the sound is truly impressive.

    Pros: Well constructed product, easy mounting, rich sound and bass better than expected.

    Cons: None thus far. Been installed for about a month now.


    Mark from waterloo sc on 5/21/2015

    Crutchfield Customer Review (What's this?)

    I had the atrium 5s...which were outstanding. So, like the typical guy I thought bigger must be better. I purchased the atrium 8s sdi's. Powered by my adcom 555 amp the sound was unbelieveable. Deeper bass..better mids and highs crisp and clear. Separation when using two at each end of my balcony was startling. Sounded as if I was standing in front of the band. Careful with your outdoor volume control. I have burned through three niles controllers but that's more of my power issues..too much. Stay to the spec. Crutchfield is the best for customer service hands down...anywhere. With the recent price drop you will not be disappointed.

    Pros: Better everything as far as sound if you use the right space...amp...and set up

    Cons: Let them for awhile They get better the more you play them. There is a break in period. I suggest dynamic jazz, symphonic or cuban music at about half volume for about 80 hours.

    Easy to install and sound great installed under a wooden 12' high deck. Located near Atlantic Ocean, exposed to salt atmosphere. Will see how they hold up over time

    Pros: construction appears substantial, easy installation


    Awesome outdoor sound!

    Crutchfield Customer Review (What's this?)

    I bought these to replace some worn out Boston acoustic patio speakers and they didn't disappoint! Well worth the money!

    Pros: Clear, nice low frequencies, the ability to run one speaker in stereo

    Cons: None

    Great speakers

    Poolside from Arizona on 1/7/2015

    Crutchfield Customer Review (What's this?)

    I can't say anything but good things about these speakers! WOW - as the other reviews have stated!

    Pros: These are great sounding speakers, easy to install - with many variations to fit any situation, can use singly or in pairs - I choose a pair, a pleasure to my semi-audiophile ears. Can't wait for summer to be able to listen to them more as the temperatures warm-up!!

    Cons: Can't think of one "con" to say about these.

    Crutchfield Customer Review (What's this?)

    While building my new home I wired everything up for my outdoor space fully intending on purchasing the Polk A7's. I wired up for four of them...well when it finally came time to make my purchase the A7s were not available anymore so naturally I just went up instead of down and got the A8 and Wow!!!! I have about a half acre back yard and I just bought two to get me started and they put out so much great sound well idk when I'll buy the other two don't even question it if you are thinking of these you will not be disappointed

    Pros: Amazing sound high and low! Excellent build quality! Easy to install! Aesthetically pleasing!

    Cons: None so far I love these speakers!

    Outstanding speaker

    Rodboy from Hamilton, Ohio on 8/31/2014

    Crutchfield Customer Review (What's this?)

    I have been looking for a good outdoor speaker for some time now. I have all polk speakers in my system but was concerned about their expertise in an outdoor environment. Due to brand loyalty I ordered this atrium 8 and have not been disappointed. I have never heard an outdoor speaker sound as good as this one. I have audiophile friends that have them all so I have listened to quite a few others. This speaker has unbelievable bass response. It's like having a sub outside. The mounting is very flexible. I have it wired to receive both stereo channels. I only bought one speaker to test it out before ordering another. On listening to just one I don't think I need two since it sounds so good. I could go on and on but I'll cut it short. I don't like typing a lot. My nickel's worth to someone looking for an outdoor speaker is to take a look at this one. There is no better in my opinion. But if you want to chase your tail to find something better and more expensive. be my guest. Good luck on that.

    Pros: Extremely good sound. Excellent bass. Very good mounting options.

    Cons: None

    Crutchfield Customer Review (What's this?)

    Love the Atrium 8 speakers. We bought these to use for our daughters wedding. We had the wedding on our lake lot and we were worried that the sound would be lost due to the size of the outdoor area. The speakers were awesome. Such great surround that you couldn't tell where to music was coming from. I would highly recommend.

    Pros: Great sound for large out door area's.

    Cons: Non

    Atrium 8 SDI WH

    JohnG from Baltimore, MD on 2/3/2012

    Crutchfield Customer Review (What's this?)

    I have several Polk Audio speakers (7.1 home theatre in-wall with powered 10 inch subs and a couple of auxiliary LC80FX in ceiling speakers). I've never gone wrong with Polk and so far this speaker is no exception. The audio quality is excellent. I think the biggest factor in my overall satisfaction will be whether or not it holds up well to the elements, though, and it's too early to say.

    Pros: Great sound. Versatile (can be used as a single unit with two sets of drivers receiving signals from two sides of a stereo output, or as one of a set of multiple speakers in a conventional setup). Substantial mounting hardware that is user friendly.

    Cons: Fairly heavy. Fairly expensive.

    WOW- Super Powerful

    purchased this for my backyard where my patio and pool is. This speaker is extremely powerful. Sounds clear, looks great, so glad I purchased this item. I put it under my eaves and added the niles weatherproof volume control from crutchfield. The volume control is a must have with this product. Awesome.

    Product Research

    Outdoor Speaker
    Driver Technology
    Enclosure Design
    Mounting Options

    Outdoor Speaker

    Weatherproof Design: Polk Audio All-Weather Certified, Atrium Series speakers exceed baseline 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.) Certification means Atrium speakers can effortlessly withstand the outdoors, and hold up in extreme temperatures and precipitation.

    Driver Technology

    Polk Patented Technologies: Patented Dynamic Balance and Klippel Optimization technologies ensure the perfect material performance, eliminating driver and tweeter "artifacts" for more realistic sound reproduction at high and low volume levels.

    • Dynamic Balance: A Polk perfected method of analyzing a speaker's microscopic behavior with laser Interferometry. Polk engineers can tune out unwanted resonance and distortion with the right combination of materials, geometry and construction techniques. This brings you pure, distortion-free sound.
    • Klippel Optimization: By using a state-of-the-art Klippel Distortion Analyzer, Polk engineers were able to optimize the woofer's motor structure, voice coil alignment and suspension bringing you the best possible performance even at extreme listening levels.

    6.5" DVC Woofer: The Polk Audio Atrium8SDI uses a dual-voice coil long-throw aerated polypropylene 6.5" woofer for clean midrange and deep, accurate bass. The dual voice coil design adds greater efficiency and power handling. For a smoother response and improved durability, the woofer uses a butyl rubber surround.

    Dual Tweeters: The Polk Audio Atrium8SDI has two 1" anodized aluminum dome tweeters with rubber surrounds and neodymium magnets for better power handling, smoother response and greater accuracy. This Dual Tweeter Array features Stereo Tweeter Aiming for excellent imaging, allowing you to use the Atrium8SDI as a single stereo speaker, or as half of a stereo pair.

    Enclosure Design

    Rugged Enclosure Design: The durable, mineral-filled polypropylene cabinet design, with molded-in bracing, sounds like a real speaker (not "an outdoor speaker"), and survives years of seasonal changes, for great sound, no matter what the weather. The rugged, mineral-filled polypropylene enclosure features a rustproof aluminum grille, rustproof aluminum bracket, and stainless steel/brass hardware.

    Note: The speakers are available in a black or white finish. The enclosure is also paintable.

    Broad Coverage Baffle Design: The sculpted front, steeply-angled baffle design and rounded enclosure minimize diffraction (sound reflecting off of hard edges) for more open and lifelike imaging.


    Dual Input/Single Input Feature: A rear mounted switch allows the Atrium8SDI to operate as a single, dual-input speaker for stereo applications, or a traditional single-input speaker for left or right use. When using the Atrium8SDI as a single stereo speaker, the dual tweeters and dual voice coils handle the left and right signals independently.

    5-Way Binding Posts: The Atrium8SDI has two sets of gold-plated 5-way binding posts that will accept bare wire, pin connectors, spade connectors, and banana plugs (single or dual).

    Mounting Options

    Speed-Locking Mounting System: The included rustproof aluminum bracket allows multiple mounting options and is quick-and-easy to install. The Atrium8SDI can be mounted either horizontally or vertically and aimed to deliver the best possible sound in a variety of situations The integrated bracket provides full 180-degree rotation (when mounted vertically or horizontally. The mounting bracket even allows the speaker to be mounted snugly in a corner or under an eve (at a downward 45-degree angle). You can remove the bracket and use the speaker's built-in stability feet, if you simply want to place the speaker on a table or shelf.

    This speakers have 6 in woofer and two twetters. They can be connected like singels, one channel in one speakers or combined, two channels in one speaker. Sound is good for outside speakers and support any weather. Are exelent speakers for backyard. [ Manuel  Feb 14, 2017 ]

    These outdoor speakers are as good as any I have heard. Nice bass and midrange. I tend to play louder than my neighbors might like only because they sound sooo great! [ O  Feb 01, 2017 ]

    I have several channels on my amp and run them separate as left and right. Good luck, I have mine outside by the pool and they can fI'll a big area pretty well [ RODNEY  Dec 03, 2016 ]
    Thanks for your question. For information on comparing two or more models I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget. [ Kenny  May 17, 2016 ]  Staff
    yes can pair in a zone .you will notice more base fro the 8 but volume should be the same [ CAREY  Feb 25, 2016 ]
    We only have delivery within the United States and U.S. territories. The only other options are deliveries to military bases with an apo/fpo address or shipping to a freight forwarder with a U.S. address. Hope that helps. [ Kenny  Feb 03, 2016 ]  Staff
    Neil, You don't have to own a receiver, but you will need an amplifier to get the proper amount of volume out of these speakers. You can connect your TV to the amp. Each Speaker can handle about 125 watts rms, so look for something with a rating of 75 watts rms or better, but don't exceed 125 watts rms. Thank you, [ Dusty  Jan 26, 2015 ]
    The speakers only have inputs for speaker cable. Unless you have a method to convert those into AV components or something compatible with your TV, then a receiver is the only way I know of to use these with a TV. [ Amy  Jan 26, 2015 ]
    You will need a receiver. [ Brian  Jan 25, 2015 ]
    Hi Neil, these are excellent speakers and I love the clean sound coming out. Yes, you will need a Receiver. I have mine connected to a Niles amplifier connected to my Denon Receiver. [ Richard  Jan 25, 2015 ]
    The price listed is per single speaker on this particular model. [ Jeff  Dec 06, 2013 ]  Staff
