Atrium Series: The Speaker For All Seasons
Atrium65
SDI
Polk Audio Atrium Series Loudspeakers meet or exceed industry and military specifications for environmental endurance. The tests have coded
names like “ASTM D5894-UV Salt Fog,” “Mil standard 810 Immersion” and “Mil standard 883 Method 10098 for salt and corrosion.” Passing them
means that Polk Multi-Application Loudspeakers can withstand some of the worst that Mother Nature (or your bathroom or kitchen installation
location) can dish out. See more about Mil-Spec Waterproofing at www.polkaudio.com/catalog/technology/. (Atrium 45p for indoor use only.)

High tech composite materials make Polk Audio Casket Basket Driver Baskets acoustically inert (acoustically “dead,” get it?). Casket Baskets
keep the moving parts of the LCi Series drivers in rigid alignment and successfully damp performance-robbing resonance. See more about
Casket Baskets at www.polkaudio.com/catalog/technology/.
Atrium60
You’ll appreciate the Atrium60 for more than its ability
to fill large spaces with big, life-like high quality sound,
because the Atrium60 is built to withstand the elements
as it delivers years of great performance.
6 1/2" mid/woofer with mineral-filled polypropylene
cone and butyl rubber surround for excellent midrange
clarity. A 2 lb. ceramic magnet ensures high output
and precise control for sound big enough to fill
the great outdoors.
1" metalized Dome Tweeter with neodymium magnet
delivers exceptional accuracy.
PowerPort, Polk’s patented port venting technology,
delivers high efficiency and extraordinary bass response
in a modest cabinet size.
Meets or exceeds ASTM D5894-Salt Fog, Mil Standard
810 Immersion and Mil Standard 883 Method 10098
for salt and corrosion tests.*
All stainless steel and brass hardware for years
of rustproof reliability
*With supplied Port Plug installed. Use the
product with PowerPort
®
venting in sheltered
locations for best bass response. Install
