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.

Rating:  - another great speaker via Polk
Own several Polk speakers and love them all.
Mounting bracket is sturdy and well designed to hold speaker in any position. Good job Polk!
Rating: - Polk Atrium 45 - OUTSTANDING outdoor speakers for a low price
I purchased these speakers to mount outdoors, under my permanently camped 31' travel trailer. I am very pleased with the sound quality and am surprised at how good the bass response is. Don't get me wrong, you won't mistake these speakers for a 15" subwoofer, but they sound very full and solid for small speakers with 4.5" woofers that I paid only ~$120 a pair for.
I am driving them with an Aiwa CDC-X504MP car stereo that puts out ~20 watts/channel into 4 ohms. Since the Atriums ... Read More
Rating: - Great product for the price
These speakers sound great for the price. I've only had them for a little over a month so i have no idea how long they will hold up or if they will make it through the winter.
Rating:  - Relatively speaking...
Folks, let's not get overheated here. The reviews salivating over this product are a bit long on hyperbole and bit short on perspective. For some perspective, let me say that I ran my white Polk 45s on the B channel of an NAD receiver, with a pair of nice (but by no means extravagant) Wharfedale Diamond 9.1s on the A channel. No comparison. Absolutely no comparison. The full audio range was better represented on the Diamonds. Put bluntly, running these guys against a set of true speakers made ... Read More
Rating:  - Great Speakers
These are great speakers for the money. I would recommend these to anyone looking to enhance their backyard with some tunes.
