Product Description

From the Manufacturer

Exceptional sound anywhere you want it – really, anywhere. The compact Atrium® 4 Outdoor Loudspeaker meets or exceeds military specifications for environment endurance. Its small size makes it ideal for tight, out-of-way installations: by the pool, next to the deck or patio, around the kitchen, tucked away in the family den or filling the backyard with great sound. The easy to mount Atrium 4 will deliver high performance audio fall, winter, spring and summer, bringing years of outdoor enjoyment. Available in durable, weatherproof black or white paintable finishes.

Key Features

  • 4 1/2" (11.43cm) Dynamic Balance® long-throw mineral-filled polypropylene cone driver with butyl rubber surround pumps out surprising bass response from a compact design.
  • 3/4" (19mm) Dynamic Balance anodized aluminum dome tweeter with rubber surround and neodymium magnet for better power handling and smoother response.
  • Broad coverage baffle design fills a large open outdoor space with big, full-range sound. The Atrium 4 has a more steeply-angled baffle design that maximizes critical mid- and high-frequency dispersion over a large area, without sacrificing detail.
  • Speed-Lock® Mounting, the easiest, fastest and safest of all mounting systems.
  • 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.) Polk All-Weather Certification means Atrium Speakers can effortlessly withstand the worst mother nature can dish out, whether its extreme temps or heavy rains.

Why you should consider this product

If you're looking for great high fidelity sound and a speaker you can locate even in the most exposed locations and forget about, the Atrium 4 is the one to choose. Its high quality components deliver impressively big sound from this small, unobtrusive loudspeaker, and its compact size makes it ideal for tight, out-of-way installations. Easy mounting, four-season durability, and the award-winning Polk Audio sound, what could be better?

Technology

Dynamic Balance®. Polk perfected the method of analyzing a speaker's microscopic behavior while in motion using laser Interferometry. With that information in hand, Polk engineers select the ideal combination of materials, geometry and construction techniques to literally "tune out" unwanted resonance. The result is a speaker that delivers pure, distortion free deep bass.

Klippel Transducer Optimization. Using a state-of-the-art Klippel Distortion Analyzer, Polk engineers optimized the transducer's motor structure, voice coil alignment and suspension for longer excursion and greater linearity bringing you the best possible performance even at the most extreme listening levels.

Speed-Lock® Mounting System. Our proprietary system for easy, safe one-handed installations even in difficult locations. The greatly simplified mounting procedure means the end to "juggling" at the top of the ladder. Simply mount the bracket and click the speaker into place. Aim it, tighten it down, and fini! Outdoor convenience, indoor sound quality! The new bracket also has a 45-degree down angle. Why adjust a speaker to a 45-degree angle, when we can design a mounting bracket that lets you install the speaker at that angle permanently? It's another feature of Atrium's new mounting system and a simple, elegant solution.

1To ensure a valid warranty, Polk loudspeakers must be purchased at an Authorized Polk Audio home or car loudspeaker Dealer (such as Amazon.com). (If you're not sure a dealer is "authorized," call Polk Audio at 1-800-377-7655, and ask us.) The warranty is not transferrable, that means it applies only to the original purchaser. If you purchase your speakers from a private individual, that product is considered "used" and has NO factory warranty, no matter what the seller implies. The warranty is VOID if the serial number of the speaker has been removed or defaced. If you have any questions about your warranty coverage, or you think you need service, call Polk Customer Service at 1-800-377-7655. We're here to help you get the most from your new speakers!

Product Description

First introduced in 2002, the outdoor Atrium Series set a new standard not only for build quality, but sonic performance, too. But we couldn’t leave well enough alone. Not only does our new, refined Atrium Series offer better sonic performance and easier install/mounting options, the series also exceeds the standard military specification weather tests, setting a new standard for rugged outdoor durability under our own more rigorous weatherproofing certification program. The results are a pure joy to listen to. So that wherever you put your Atrium speakers—by a pool, on a deck or in a sunroom, you can be confident they’ll deliver great sound year round.

Bass is adequate and overall sound is clear, even at high volume.

I still have never "cranked" it up, haven't felt the need. but I'm sure they will preform well if I ever feel the need to entertain the neighborhood!

I love this speaker !! It has a great sound for the $$. The mounting bracket system is heavy duty, very versatile and easy to install. I installed mine going horizontally in the corner and due to the 180 degree pivot lock system I could get them just at the right angle in no time at all. I'm using them in an indoor spa enviorment and had no problems with humidity effecting the speaker.

I would say great speakers for the price but I'm not sure how much better more expensive speakers would sound. I have these installed outside under a deck and they really throw out sound. I'm not an audiophile but I know when a speaker sounds good or not and these sound great. I'm not sure you can find a better speaker for the value.

I have the Atriun 4 pair set up mounted to my house above the deck, powered by a 100 watt Sherwood Amp/receiver. Incredible sound from 20 yards out to the back yard (crystal clear) at a moderate volume.

Easy install with nice adjustable mounting hardware. I thought i'd need a second pair prior to turning on the speakers due to being outside but found the pair to be more than enough sound for entertaining.

I put a lot of research into enviornmental speakers and tried all the top brands (Bose, Boston Acoustics, Yamaha ect.) and found the Polk Atrium to be the superior sound. Try them out in your local electronics store then purchase online. I saved 50%.

I have yet to crank up the volume but wish not to piss off the neighborhood at this time. If you choose the Polk speaker you will not be disapointed. Some who want a little more bass may want to look into a woofer but for my purposes, i need nothing more

3 of 3 people found the following review helpful By Audio Nut on June 25, 2013
A buddy gave me a set of these for helping him build his home theater room. Several years later, these are still playing perfectly outside on my deck/pool area. And I drive them hard with a 100 watt per channel amp. I had some Bose prior to these but the Polks sound much better, in part because they have real tweeters. With only a 4.5" woofer, the bass is not huge; but I use a subwoofer with them. Everyone is amazed at the sound I have outside at my pool.

These are high quality with amazing sound for outdoor speakers. I highly recommend them. The only outdoor speakers I have heard that will rival Polk is Klipsch.

I needed to write a review for these little guys. I am a Polk fan, I will admit it, but I wasn't expecting much from these speakers as they were under a Benjamin Franklin and just 4.5" drivers. I wanted something inexpensive and small, and I didn't need something to "rock" my deck...as I have fairly close neighbors. I only have about 6 hours of playtime on these so far (not yet broken in), as its still winter here in Colorado, but these deliver much more than I expeced. I have them perched under the eave on our patio facing down on the deck, as to try and not to distub my neighbors. For the price, they sound incredible. Crisp and clear highs and punchy bass. Their low end is not too deep, only a 4.5" driver and small sealed cabinet, but nevertheless, they have a nice full sound. Don't expect miracles here people. Can I find better?...of course. Can I find better at this price...good luck trying to find it. Brackets are an engineering feat...installation was so simple and adjustment is as well. Before I installed them, I had buyers remorse thinking that I should have at least bought the Atrium 5, or Def Tech 5500...but that remorse is gone. Any more speaker wouldn't serve much more purpose on our deck...and the price was, well...perfect. If I had wide open area or a pool, yes, I would have gone bigger. But like I said, these fit the bill...perfectly.

I installed these speakers under the roof of my screened in patio against the house. They are powered by zone 2 of a Yamaha network receiver. Very well built. Heavy construction. Music sounds great all the way to our fire pit some 20 yards away. Highly recommended equipment.

These are pretty good speakers. Put them on my back porch so everyone can enjoy music around the pool. The brackets made it easy to mount on the wall. They actually gave me a few choices for mounting. Once they were wired into the stereo, I turned on and enjoyed. The sound wasn't mind blowing but, in all fairness, I haven't played much with the audio settings on the stereo. I will say, they get as loud as you would like. I've had them so loud the neighbors came out, oops. If your looking for something outside that can take the volume and look good, these are it. Almost forgot, I've only had them installed for about a month but feel they won't have a problem in the weather. They are protected from Rain and direct sunlight so not concerned about longevity. I like these speakers and hopefully they will last a long time. Hope this helps
