These replaced a pair of buzzy 10 yr old JBL's on our back porch. What an improvement -- especially in the low frequency range! Thanks Crutchfield for a very good deal on an excellent product!

Was expecting more bass from these. Outside the sound from these is weak. I have them on my back fence and have to strain to hear them. Maybe on a patio they work better.

Pros: Price

Cons: Thin sound.

good, but not great

Anthony from Raleigh, NC on 5/23/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

They are good, but not great. I have a Sonos One in proximity, and if I compare them head to head, the tiny little Sonos as a bigger bass. Outside of this, they handle the mids and highs quite well. For the money, they are a good buy. If you need a deeper sound, get the next size up

Pros: Compact, easy to install, look great

Cons: Missing a deep bottom end

I'm very pleased with these speakers, which I'm using for surrounds in an outdoor 9 channel theatre set-up. Installation was excellent... easy and very secure. Sound is well beyond what I expected for their price tag. I'd absolutely purchase again. As always shipping/packaging with Crutchfield was exceptional. Used my reward bucks to attain these. Thanks Crutchfield!!

Pros: -Set up -Sound for price -Attractive

Cons: Bass response... but not bad given woofer size and price

Needed replacement speakers for our deck. These fit the bill perfectly. For their compact size they have an amazing sound. Easy to install and since I alreadt had the wires run easy to hook up. Now we can enjoy music or garden shows in our back yard, Hopefully they will last for years to come.

I have a pair of the Bose 151 speakers and decided to try these as I didn't want to spend the $ for another pair of Bose. I couldn't be happier with these speakers! The sound is amazing at all ranges. They look great and the way that they attach to the bracket is just too easy. My only con would be that the terminals are too close together so hooking up the speaker wire can be a little tricky if you have normal sized fingers(most speakers have this setup). Don't waste the money for the Bose speakers....you'll be happy you didn't...

Pros - Arrived quickly and in perfect condition - Sound great (highs and mids really crisp, lows are good considering the size) - Size and shape perfect for where we wanted to mount them under the eaves - Mounting brackets and design make for easy install and adjustment - Great value for the money Cons - None so far Just installed them a few days ago paired with a 120W Pyle amp.

These speakers sound great out in my garage. I mounted them up high on the rafter beams, aimed them on a slight downward angle, and I swear I haven't heard music sound this good in my garage ever. I was going to mount these outside on my patio wall , but after I heard them in my garage , I didn't want to give them up to the patio. I guess I may just need to buy a 2nd pair!

Small and nondescript. The sound is about what I'd expect for a speaker of this size at this price point. It lacks definition in the mid-range, and there is a distinctive mid-bass peak, but the overall bass is better than you might expect for something this small. Presence and dispersion is excellent. Installed on our front porch.

Pros: Small, nondescript.

Cons: Sound quality is mediocre.

I bought these to replace older ineffective speakers on my deck. Replacement installation was easy and took about 15 minutes. Enjoy listening to music as my wife and I relax on our deck. These Polk speakers provide good separation of vocals and instruments in the underground, deep tracks, and classic rock 'n' roll songs played. Very good value for the cost of the speakers.

Replacing a pair of no name brand from another retailer (mistake!) for the out side pool area that lasted two years. The brackets and speaker case are affected mostly due to the weather here in Central Florida, beating sun rays, rain, and pool chemicals. Had them for three months and the brackets have held up, no rust. The speaker case is like new and the speaker delivers clear crisp sounds. Could use more bass, but for the $, it does the job.

Sound great and easy to install. I have them installed outside on the patio, installation was easy, however the 5 way binding posts do not support a standard banana plug. The angle of the posts blocks access for a standard banana plug from the back of the posts. I had to insert the banana plugs into the binding post screw opening and then snugged them down. The connection seems to work fine and they continue to sound great.

Pros: Value/Price. Easy to install. Sound and look great.

Cons: Standard banana plugs do not fit due to the angle of the posts.

I installed these speakers on my side patio and my back patio 2 years ago. I've been very pleased with the quality of sound on these speakers. Sound is crisp and bass is good. While I rarely write reviews, I felt inspired to do so as I'm writing this on my side patio with Kings of Leon playing through Pandora on my iPad streaming through Airport Express to my older Onkyo receiver. I'm really pleased with these speakers and planning to install another pair in my basement for working out. What I like is the quality at low and high volume. Thank you Crutchfield for helping me figure out the install.

Pros: Quality of sound - Small enough (some speakers are really large) - Still working after 2 full seasons of Colorado's winter and summer extremes.

Cons: None - I'm really pleased with these speakers.

Based on the majority of reviews, I though these would have much better sound quality. They have virtually no bass. Turning up the bass on the receiver only caused distortion.

For the size and price these Atrium 4's sound fantastic. We ran some 16 gauge wire out to the back deck and mounted these in both corners so we could have them face the house or swivel out to the the patio. The sound is great with no distortion up to rather high volumes. Wire hook up is easy with the 5-way posts and installation is also easy with only two wood screws needed for each speaker bracket. Easy to pop into the brackets once mounted but more difficult to pop out. Solution, just slide the bracket and speaker up and out of the screw mounts and take the whole thing inside when needed. Very convenient. These also appear to be very versatile with multiple mounting options/angles. Great value, great sound.

Pros: Great sound with no distortion up to rather high volumes, handsome, easy to pop in.

Cons: Not so easy to pop out.

I use them for a patio, and delivers the right sound for a patio. I use the Atrium 7 for a larger & open pool area and main outdoor speakers.. These speakers will do great for a smaller area. Otherwise, step-up to the Atrium 7. Different sound category, different price category as well.... Different size as well. Atrium 7 are really bigger. If you hesitate, go for the Atrium 7, you won't be disappointed.

Pros: Quality built Great sound for a small/medium size area Smaller size make them easy to use in smaller outdoor spaces

Crutchfield and Polk always seem to have some sort great speaker deal going. Since I bought over a certain dollar amount of Polk speakers, they threw in the Atrium 4's for free. Fantastic. I was putting speakers on the deck anyway, so why not mount them by the grill to supplement the sound? It works great. I was not expecting much from these little speakers but I am super impressed. I get plenty of volume and crisp, clear audio. I was expecting the bass to be really anemic but it's pretty good for speakers of this size. The build quality is top notch and mounting them couldn't have been easier. Polk's Atrium series is a winner. Taking advantage of the Crutchfield/Polk offers is a no brainer.

Pros: Great sound for such a small speaker. Very easy mounting.Good price point.

Cons: None so far.

Not enough bass to sound good in a small backyard. I cranked up the bass on the receiver, but got lots of nasty distortion when I gave them only a modest amount of volume. Should have spent the money to get something decent. Will see if the sound improves after they've acclimated to outside conditions but I'm not optimistic. Probably stuck with them as installation marred the white finish. Ugh.

Pros: Compact design. Easy to install and great flexibility in how to direct sound. Look nice. Inexpensive.

Cons: Not worth even the modest price if they can't handle bass.

Clean, clear sound quality. Fills your outdoor space with music that no boom box can match. These white waterproof speakers looks great and perform well. You find yourself spending more time outside. No regrets

Pros: Compact, easily adjustable, good clarity. Quality from Polk you would expect

Cons: Non yet.

Speakers are crystal clear, stereo has never sounded better. Just the right size to fit under the eves with room to adjust if necessary. Best birthday present ever.

Pros: Ease with installation, crystal clear sign.

Cons: Had to block with screen netting, Robins trying to nest on them.

My recent purchase of Polk outdoor speakers was a replacement for older Polk speakers I have had for over 10 years. I have to say the the quality that Polk builds into their products translates into great sound and longevity. My new speakers provide excellent sound reproduction in my outdoor pool/patio area. I would recommend Polk products to everyone!!

Very Good Outdoor Speaker

TC from Shorewood, IL on 8/23/2011

Verified customer (What's this?)
Verified employee purchase (What's this?)

I installed these speakers on an outside wall, just beneath the eaves. Due to their size, I was able to install them exactly where I wanted. The supplied bracket with swivel allowed me to rotate them where I needed the sound to go. Very good sound for their size and price. I would give 5 stars if they had a little more bass, but they did quite well for a 4" woofer.

Speakers are small but provide a nice sound. Surprised at the base that's output...I wasn't expecting a lot and they came out sounding nice. Fairly light weight so hanging them wasn't an issue with just some regular exterior screws.

I really like these speakers! They look good, and are not too big. I use them outdoors, and am really impressed with the sound! They have great bass for their size! The closer you put them to your eves, the more bass you will hear. I was also impressed with how well they "spread" the sound. I also like the fact that they are so weather proof. For the money, you can not beat them! Highly recommended!

Russ from Plymouth, MI on 5/2/2011

Verified employee purchase (What's this?)

These speakers do not handle as low of frequencies as I would want for indoor speakers, but the mids to highs are wonderful. The light amount of bass is perfect for my small backyard so that I do not disturb my neighbors. Also, the mounting brackets allowed for me to easily mount these speakers under my eaves and point them down towards the center of the patio. As always, Crutchfield delivered the speakers quickly and provided an extensive amount of additional support.

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.

Woofers: Each speaker features a 4 1/2" (11.43cm) long-throw mineral-filled polypropylene cone driver for clean midrange and deep, accurate bass. For a smoother response and improved durability, each woofer uses a butyl rubber surround.

Tweeters: Each speaker features a 3/4" (19mm) anodized aluminum dome tweeter with rubber surround and neodymium magnet for better power handling and smoother response.

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.

Connections

5-way Binding Posts: The Atrium 4 has a pair of gold-plated 5-way binding posts that will accept bare wire, pin connectors, spade connectors, single- and dual-banana plugs.

Mounting Options

Speed-Locking Mounting System: The included rustproof aluminum brackets allow multiple mounting options and are quick-and-easy to install. The Atrium 4 can be mounted either horizontally or vertically and aimed to deliver the best possible sound in a variety of situations The integrated brackets provide full 180-degree rotation (when mounted vertically or horizontally. The mounting brackets even allow 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.

I have a Panasonic receiver that has a rated output of 100W at 6 ohms. Can I use the atrium 4 since it is rated at 8 ohms?
[ Shields  Mar 10, 2019 ]
1 answer
A
Hi, I am not an expert though my opinion is it is ok to use 8 ohm speakers with a 6 ohm receiver. I also think you will need turn up the volume to get the same volume you would get from an 8 ohm receiver. The pro's at Crutchfield should be able to help you out.

Hi - I am looking for some out door speakers, however, I live in a very salt weather environment (an Island in the Caribbean). Are the brackets painted mild steel? Does anyone have them mounted on a boat (in the ocean, not fresh water) for instance?

I have this speaker mounted on my boat in PR for 1 year ago with no issues. Sound super. You have to buy goods cables

I have these speakers mounted on a tiki bar outside in a waterfront home. (saltwater). Have had them for nearly 2 years and no problem at all.
[ Rebecca  May 01, 2018 ]
A
I don't have them mounted in the salty ocean area as you, but I do have two sets installed in Wisconsin. Lots of snow and freezing weather. They have held up great. Am actually ordering three more sets for another customer. I'm an electrical contractor, always a great product. (Polk Audio)

can these be hooked to a computer for streaming from, say Pandora?

There are the normal speaker wire terminals.
[ Michael  Apr 05, 2018 ]
A
Sure. I bought a Bluetooth adapter from peach tree audio and connected it to an old stereo reciever I bought on Craigslist and connect my IPhone to listen to Pandora all the time. Great outdoor speakers.
[ Mark  Apr 05, 2018 ]
A
They are not designed for direct connection to a pc. The pc would likely not have enough power in the sound board to drive these.

Hi: Can be used on a beach house outdoor?

Personally, I don't see why not. I live in Michigan and since I mounted them outside on my deck 2 years ago I haven't taken them down. They still work like new. However, I would take them down if you don't live there year round because if other people hear them, they may walk away when you aren't there if you know what I mean because they do sound good. So good that I bought a second set for a place we have up north.

Should be fine. As with anything in salt air the life might be reduced vs a normal porch.

A
Yes they can be hooked up to a outside tv and no they are not Bluetooth.
[ Johnny  Jan 13, 2017 ]
A
Not directly. They need to be driven by an amplifier. They do not have built in Bluetooth either. That said, they are very good outdoor speakers, but may not be what you are looking for.

There is paint on the market for to use just on plastic materials. But, I suggest you don't paint them.

Yes. Remove grill and cover cone and tweeter. I painted to match an outdoor space at a country club.
[ PAUL J  Jul 24, 2015 ]

I don't see why not, but I would go with the white ones and paint those. It might be hard to cover up the black completely.
[ Edward  Jul 24, 2015 ]
A
I would say yes, use a spray paint so the grill doesn't get clogged.

They are able to withstand the elements but I have mine up under my overhang so they don't stick out so much. They sound great. James

We have 2 sets of these speakers which have done really well outside. However, ours are mounted on outside porches with overhead cover so I'm not sure about total exposure. I do know that ours have gotten wet and icy in spite of the cover because we are on a mountaintop with extreme wind.
[ mary  Apr 07, 2015 ]

I've had them up under the eaves of my back porch by the pool for a few years and the're doing just fine. While they aren't in direct weather, the eaves are fairly short, so I'm sure they're getting partially wet. They sound great and at a reasonable price, so those were the two biggest factors for me. Hope that helps!
[ MARK  Apr 07, 2015 ]
A
Mine are under the eaves of the roof line. I'm sure they get some wind driven rain from time to time. They work fine.

Q
Do these speakers need to have an amplifier hooked up to them or are they basically a "plug and play" setup?
[ Rob  Jun 04, 2018 ]
1 answer
A
No, they do not need an amplifier. However they do perform much better with an amplifier! My present installation uses an amplifier with a built in surround sound and a sub-woofer (I strongly recommend you use a sub-woofer). I have left my speakers up, during last years hurricane, and have experienced no reduction in performance! (I live in Florida).

I USED THESE OUTSIDE ON MY PATIO. I MOUNTED THE BRACKET VERTICALLY AND THE SPEAKER CAN BE ADJUSTED LEFT OR RIGHT. IF YOU MOUNT THE BRACKET HORIZONTALLY, YOU SHOULD BE OK. THE SPEAKER CAN BE ANGLED UPWARD..BUT THE SPEAKER WILL BE TOO BIG TO ANGLE STRAIGHT UP. HOPE THIS HELPS
[ jeff  Apr 30, 2017 ]

Only if you hang the brackets horizontally.

How would these work for wall mount surround sound speakers for your home theater system in your house?

They would work fine , a little bulky for inside a house and unless you have a flood, the weather resistance is wasted inside :). Have you looked into the owm3 by Polk? They have an awesome look to them and can be mounted all sorts of ways

The woofer seems blown. Can I open this speaker to replace woofer or is it sealed shut?

We don't have any info about replacing the woofers in the Atrium4 speakers, but if yours are still under the manufacturer's warranty (5-years), it's possible Polk will replace them for you. You can contact Polk directly for more information at 800-377-7655. I hope that helps! My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=159

[ MICHAEL  Jan 31, 2014 ]

we have them mounted about 7 feet up on our terrace, the area is 10x25 feet, and they provide excellent coverage for the requirement, which is largely background music for parties

It has rained so much since i got the speakers i was unable to put them up. Sorry i couldn't be more help.
[ GREGORY  Jan 29, 2014 ]
A
I use them on my patio outside but I am not happy with the sound when you turn up the volume. They rumble and sound like a blown speaker.
[ RICHARD  Jan 29, 2014 ]
A
I use these around my pool/patio area and it is approximately 50' x 100'. The speakers are clear and plenty loud enough for my type of listening (background music). My speakers are about 125 feet from my receiver, so there is probably some more power there, but ohm draw is high at that distance. The only thing I wish I had more of, is some bass, but I really can't expect too much boom boom from ceiling mounted speakers. Overall, I am happy with these. They look good, sound good, and mount easily.
