Refined for the Great Outdoors
The Atrium5 loudspeaker steps up the sonic performance with a 5-inch
driver that produces high fidelity sound quality anywhere you want
great sound. The speaker's mineral-filled polypropylene cabinet can
stand up to the elements year round. And its new one-handed Speed-Lock™
mounting system makes installation fast, easy and safe. The mounting
bracket even enables a 45° angled mount aiming down into a listening
area.
5-inch (12.7cm) 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 rubber
surround and 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.
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.
