Own several Polk speakers and love them all.
Mounting bracket is sturdy and well designed to hold speaker in any position. Good job Polk!
Polk Atrium 45 - OUTSTANDING outdoor speakers for a low price 2008-09-29
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 are 8 ohm speakers, I get less than 20 watts/channel. If I were buying an amp, I'd buy one with more power, but I had the Aiwa lying around. My setup easily fills my 30'x20' camper lot with quality sound, however, this setup will not provide ear splitting sound levels.
I was very impressed with the weight of each speaker; I was also impressed with the build quality of the enclosure and the gold plated 5-way connectors.
Overall - The Polk Atrium 45s are an outstanding value. I would highly recommend them.
Great product for the price 2008-09-22
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.
Relatively speaking... 
2008-09-09
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 the Polk's deficiencies far more apparent. The mids are muddled, the highs a bit too tinny. I was impressed by the bass for speakers of this size, but ultimately found the sound to be comparable to a decent set of computer desktop speakers with attached subwoofer.
Now, for a bit more perspective, one does need to consider how these speakers are to be used. If you intend to use these outdoors, they may be perfect for you. They seem incredibly solidly built with good engineering all around. They are visually attractive and just the right size to produce decent sound while remaining relatively inconspicuous. The brackets and grills are stout. Given that an outdoor environment comes with its own background symphony of noise, my quibbles with the quality of the sound may be taken with a grain of salt. I am sure we will be happy using these guys outdoors on our patio. But given the limitation in sound quality, that's precisely where they will stay.

These are great speakers for the money. I would recommend these to anyone looking to enhance their backyard with some tunes.

Polk 45 Atrium Speakers 2008-08-31
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 2008-08-29
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.
Awesome sound 2008-08-29
I spent a lot of time reviewing different outdoor speakers. I decided on these because I have always like the quality of Polk. I hooked these up about 4 months ago and found they work perfectly. The speakers have enough base, I haven't heard them bottom out, and they have clean highs. I was considering more expensive speakers, because I felt these might not have been able to project the deep base across my backyard, but that wasn't the case. These are a good choice.
SOUNDS GREAT 2008-08-28
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.
