Polkaudio Atrium7  Outdoor Loudspeaker

The Speaker for All Seasons

Bigger is always better when you want to fill your outdoor spaces with real music. The Atrium7 has all the Polk features that produce big, lifelike high quality sound. And because the Atrium7 is built to withstand the elements, you can expect it to deliver years of great music listening.

Atrium7 Features:

6 1/2-inch (16.51cm) long-throw aerated polypropylene cone driver with butyl rubber surround pumps out surprising bass response from a compact design.

1-inch (24.5mm) anodized aluminum dome tweeter with rubber surround and neodymium magnet for better power handling and smoother response.

Patented water-resistant PowerPort® bass venting efficiently adds 3dB of big, realistic, musical bass output. No other outdoor speakers can touch the Atrium Series for deep bass you can feel from the ground up.

Broad coverage is created by a more steeply-angled baffle that maximizes critical mid- and high-frequency dispersion over a large area, without sacrificing the detail.

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.

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.

Polk all-weather certified means the Atrium7 exceeds 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.)

Aluminum grilles and bracket, with stainless steel and brass hardware  means no rust. Ever.

Gold plated 5-way binding posts for the most secure, efficient 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.
