Polk Audio presents speakers so tough that even a desert war zone can't kill them. The Atrium5 speakers feature stainless steel and brass hardware to eliminate rust worries, even outside. These speakers meet or exceed various government standards for salt fog, immersion, salt and corrosion tests. The 5-way binding posts are gold plated to prevent corrosion.

The speakers are a 5" mid/woofer with a mineral filled polymer cone and a 0.75" Anodized Aluminum dome tweeter with Neodymium motor structure. The sculpted front baffle and round enclosure minimize diffraction and deliver a more open, natural sound. The aluminum grill is 55% open for superior sound transmission without compromising the protection it gives the cones.

  • newegg Exceptional Sound Quality The Polk Audio Atrium5 boasts a 5" Dynamic Balance, mineral filled polymer driver and a 0.75" Anodized Aluminum dome tweeter to deliver crisp highs and accurate lows for an immersive listening experience.
  • newegg Military-Grade Waterproofing Built to military specifications for waterproofing, the Polk Audio Atrium5 is capable of withstanding water, salt and corrosion or any harsh environment for years of reliable performance anywhere in and around your home.
  • newegg Dynamic Balance Technology The Polk Audio Atrium5 boasts exclusive Dynamic Balance Composite Material Technology to eliminate the performance-robbing resonance, so the sound is always clear and clean without any distortion.

4 out of 5 eggs

Pros: they were free with an onkyo receiver! The sound is good and it has downpoured on them with no problems.

Cons: Volume is very low although they have the same ohms as my other speakers - I was hoping they'd be louder as they're all outdoor together.
Also, they will not take banana plugs! They have a hole at the back but are angled poorly so plugs won't fit.

5 out of 5 eggswOw

Pros: Easy Install, Sounds like Polk brought their inside voice outside. Very clear and crisp, you actually hear sounds you never heard from the competition's speakers. Nice thump as well. Fills up my backyard with perfectly sounding music.

Cons: I am not always out back to listen to them.

Other Thoughts: Very nice, I actually own a set of these and won them from a karma drawing on Polk Audio's forum. Mine are demos. These demos were actually frozen in a block of ice, among other things. If someone didn't tell me, I would swear they were brand new. They sound perfectly. If I were to buy, I most definitely would buy these or a higher numerical number. My budget though, I would have bought the 4 series, and am sure those sound fantastic as well. These are perfect for my back yard. I am driving these with an old Pioneer VSX 406. They are easily driven, so I don't turn up my receiver more than half way. For those that want to go all out, try the higher numericals, but for jamming at high volumes and sounding great, these are sufficient. With these and my other Polk Audio speakers, I, in the market for more speakers of course, cars next, will go Polk Audio only and forever. Thanks Polk for putting out great speakers at an affordable price. And thanks Newegg for carrying such great products.
