Big Fidelity, Small Speaker
The compact Atrium4 loudspeaker produces high fidelity sound quality anywhere you want great sound. It’s small size makes it ideal for tight, out-of-way installations. By the pool, around the kitchen, tucked away in the family den or filling the backyard with great sound. Like our bigger Atriums, the Atrium4 is built rugged to deliver years of great performance fall, winter, spring and summer.
4 1/2-inch (11.43cm) long-throw mineral-filled polypropylene cone driver with butyl rubber surround pumps out surprising bass response from a compact design.
3/4-inch (19mm) anodized aluminum dome tweeter with neodymium magnet for better power handling and smoother response.
Broad coverage baffle design, adapted and applied from our current Atrium design but with subtle improvements in the new Atrium Series. You want to fill a large open outdoor space with big, full-range sound, The new Atrium Series has a more steeply-angled baffle design that maximizes critical mid- and high-frequency dispersion over a large area, without sacrificing the detail.
Polk 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.) Certification means Atrium speakers can effortlessly withstand the worst Mother Nature can dish out, whether its extreme temps or heavy rains. With certification like this, your kitchen or bathroom installation is a cakewalk for Polk all-weather speakers.
Speed-Lock™ mounting system, for easy, safe one-handed installations even in difficult locations. The greatly simplified mounting procedure means fewer parts to “juggle.” Simply mount the bracket and click the speaker into place. Aim it and tighten it down, and fini! Outdoor convenience, indoor sound quality!
Durable, mineral-filled polypropylene cabinet design, with molded-in bracing, sounds like a real speaker (not “an outdoor speaker”), and survives years of seasonal changes, for truly great sound, no matter what the weather.
Patented Dynamic Balance® and Klippel optimization technologies ensure the perfect material performance, eliminating driver and tweeter “artifacts” for more realistic sound reproduction at high and low volume levels.
Aluminum grilles and bracket, with stainless steel and brass hardware: No rust. Ever.
Gold-plated 5-way binding posts for the most secure, dependable hookups.
Available in durable, weatherproof black or white paintable finishes.
All Polk products are made using the best materials and the most advanced manufacturing techniques. They pass the industry's most exhaustive quality tests, including drop testing, extreme signal response and UV & salt exposure testing. Polk loudspeakers are built to perform for a lifetime.

Saw these at best buy and they are fantastic, great price too. Easy to install and comes with tips for paiting the product other colors. I acutally like these better than the more expensive Bose model

Super easy installation. Great sound.
I was looking for an inexpensive outdoor speaker with great sound quality and the Atrium4 delivers! I was a little skeptical that they might be too small to give good full range sound, but they really do have a decent amount of bass.

Quality construction, good sound, perfect size for the patio.
These are great if you're looking for smaller size outdoor speakers, which is the main reason I got them. The sound is clear and has a nice lower end and higher end as well. They can reproduce realistic sounds of saxophones and drums (Jazz fan). They should last long as expected.

Great sound, solid construction, easy installation.
Pricing in europe is horrifyfing! Amazon uk 349 GBP = 444 USD(!) Amazon.de 249 EUR = 307 USD Amazon.com 99 USD(!)
Just installed an Atrium 4 speaker set and I must say I'm pretty amazed! Good sound, especially for my purpose, upgrading my porch with music, not to be played at party levels. I really am curious how the Atrium 5-up sound! - the Atrium 4 is already awesome.

Crisp, clean, full sound.
Was concerned that the low end wouldn't be enough, but after installing them I was very pleased. I have them out on my deck, which is a very open space, and they provide full, rich sound! I also have a gazeebo out in the yard and the sound easily reach to it.
