Polk Audio Atrium7

The Polk Audio Atrium7 consists of a pair of 12-7/8” x 8-1/2” x 9-3/16” indoor and outdoor loudspeakers. It builds from the Atrium6 with a 27% increase in volume, and from the original Atrium4 with a 300% increase in volume.

The Atrium7 certainly isn’t as compact and easy-to-install as its peers, but it does feature their military 810/883 certifications for salt and corrosion. Included is 6-1/2” long-throw aerated polypropylene cone driver for bass; a 1” anodized aluminum dome tweeter; and a water-resistant PowerPort bass ventilation shaft that adds an additional 3dB of bass output.
