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.

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!

I have had a "total" sound system in my home for more than 10 years - a set of Bose indoor speakers in each of three rooms; a set of Bose outdoor speakers in the eaves over my front door and another set in my outdoor screen room; and a set of Cerwin Vega "bookshelf" speakers in my TV/entertainment room. Just today, I added a set of Polk Audio Atrium 4 speakers to the system in order to pipe sound (satellite TV/DVD/CD)to an arbor swing located about 50 feet from the back of my house. I must say, I am impressed. The Polk Audio Atrium 4s sound every bit as good as the Bose speakers (if not better), and the quality of their construction appears outstanding. As this is the the set which will be most exposed to the elements, I was encouraged by the excellent "weatherproof" specifications and the fit and finish of the Atrium 4s. Only time will tell if they hold up as well as the outdoor speakers I now have, but at a price about $100 cheaper than the least expensive Bose outdoor speakers, they appear to be an extraordinary value for the money. HIGHLY RECOMMENDED.

For $100 these are some pretty good overall outdoor speakers. I had a pair of JBL outdoors that developed some buzzing and pops so I needed a replacement and I went with these. For reference, every other speaker I own (except for a pair in the garage) is JBL, this was my first Polk experience.

Generally speaking they are a solid set of speakers. They give a pretty balanced sound all around but lack a little fullness in the lower mid-range. This is particularly noticeable when playing orchestral type music like film scores or piano heavy music. Going from the lower mids to bass is where they really start to have trouble. For the size of the speaker I certainly wasn't expecting to really "feel" bass but these do drop off noticeably in the lower frequency ranges. If there's something to knock with the Atrium 4's, that's it. With other types of music (country, rock, etc...) those issues aren't as noticeable. With that said they offer a nice high end treble sound that is pleasing to the ear. Overall the tone is brighter than I generally prefer (all of my JBL's have a warmer tone) but it certainly isn't a deal breaker for me. They don't by any stretch of the imagination sound unpleasant. For our purposes, general entertaining...using them for music outside while we do yard work..., they fit the bill very nicely. For $100 I am overall satisfied with this purchase. If you can afford to, or if a flatter overall response is important, then I'd probably look at something a little more expensive. If you are comfortable giving up some sound quality or if budget is an issue then certainly gives these a serious look.

Installing these babies was an absolute breeze. The mounting hardware supplied by Polk is virtually idiot proof. It simply could not be any easier to mount these speakers.

At $99, these are not the most expensive speakers I've ever bought, and of course not the biggest. At lower volumes you might think they're underpowered. But give them some juice. Everywhere between half-loud to uncomfortably loud you'll be shocked (seriously, shocked) at the clarity of the sound.

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 have been installing surround sound theatres in my homes for years... I was always the "First Kid On the Block" type. Also as a former accomplished musician amps, speakers and wires everwhere has been my plight for some 55 years (thats scary).

I have had the pleasure of owning speakers of all types and costs and can honestly say that polk has been my favorite choice as it provides a speaker array that can handle high watt output (8-4 ohm) and a full spectrum of audio range that is essential in obtaining a quality sound. The days of inter-modular distortion... "barking speakers" are pretty much gone from all makers shelves. But the Polk Atrium Series is a well made indoor/outdoor speaker that is perfect for your pool side, patio or onboard boat needs. However if you are looking for more punchy bass... I recommend upgrading to to Polks 6 series as the larger main speaker (woofer) has a more effective lower range. I have owned and opperated the Polk Atrium 4 in a number of differant venues with great enjoyment.

In my opinion the 4 series is a great all-weather speaker that is easy to install (comes with all the hardware) and if you have a smaller budjet 2-4 sets will fill your pool or linea area with music. However when ever possible adding two larger Atrium 6 series cabinets will enlarge your music spectrum (bass) and have a noticable improvement. I recommend placing your larger set under a soffit or at a closer quarter area to help enhance the speakers performance... becuase sound waves are all about moving air! Even the smaller Atrium 4 can sound more bass driven when placed in a more confined area that allows it to reflect/bombast more confined air. Do not be affraid to try out locations when installing multiple sets... enjoy! Tom Maroney retired Construction Engineer Boston, Massachusetts.
