Amazon.com Product Description
Tired of leaving the door open to hear your music on the deck? It's time for a pair of high-quality outdoor speakers like the Atrium 45 from Polk Audio. The speakers each feature all-stainless-steel and brass hardware for years of rustproof reliability and a rustproof aluminum bracket that permits multiple mounting options and full 90 degree rotation: you can aim them to deliver the best possible sound in a variety of positions.

The Atrium 45 speakers have a wide dispersion pattern, and they're very efficient, operating on as little as 10 watts per channel. They're designed to deliver good sound quality across a large listening area, but Polk recommends multiple-pair setups if you want high sound levels in an outdoor setting, as sound tends to dissipate more quickly outdoors than in.

The speakers' white finish is paintable to match your decor or trim color--you can even paint them green to blend with foliage. Their sculpted front baffle and rounded enclosures minimize diffraction (sound reflecting off of hard edges) for more open and lifelike imaging, and their rustproof aluminum grilles offer 55 percent open area for better high-frequency response than speakers with denser grilles.

Sealed-enclosure (acoustic suspension) cabinets result in taut bass, and the speakers' 2-way design incorporates a 4.5-inch long-throw polymer cone driver with butyl-rubber suspension and a .75-inch dome tweeter with a neodymium magnet to broadly distribute high frequencies. Gold-plated, 5-way binding post terminals will never corrode. The plugs also allow hookups in a range of methods, including convenient banana-plug-terminated speaker cable.

The Atrium 45 meets or exceeds ASTM D5894-UV Salt Fog, Mil standard 810 Immersion and Mil standard 883 Method 1009 8 for salt and corrosion tests.

Customer Reviews

Polk 45 Atrium Speakers
Installed a pair of these speakers at our patio. I'm very happy with the results, I'm by no means an "audiophile" but these speakers sound great and were very easy to install. I have a neighbor who has 3 pair of these same speakers, 2 pair on his deck and another at his garage and after listening to his speakers I was sold on buying these. Very good quality materials too, and they are paintable.

Never Disappointed With Polk
I own many Polk speakers including models dating back to the mid 80's (10's, 5's, and 4.6 series just to name a few). These Atrium 45's are my newest addition. Because of our current budget, I seriously considered spending less and therefore looked at some of the other models in the top ten sellers list. But, I am very devoted to Polk. Why? Because they sound great. If you are debating whether or not to spend the extra cash for these (like I was), I promise you will not be sorry with the sound quality and the overall quality of this speaker system. I am very happy that I purchased these speakers. One more note worthy of mention: the bass output from these tiny speakers is very impressive.

SOUNDS GREAT
I INSTALLED TWO OF THESE SPEAKERS ON FRONT OF MY HOUSEBOAT. THEY SOUND AWESOME, AND LOOK GREAT ALSO. I PLAN TO GET ONE MORE SET FOR UPPER DECK FOR WHEN WERE ANCHORED OUT AND HAVING A PARTY.
