The New Atrium Series Raises The Standard
For Outdoor Performance, Again
Sometimes it takes a lot of subtle little changes to make a great product
better. So it is with our Atrium Series. First introduced in 1991, the outdoor
Atrium Series set a new standard not only for build quality, but also for
sonic performance that has thrilled countless listeners as it continues
to create more and more Polk® enthusiasts.
Our new, refined Atrium Series offers better sonic performance, improved
weatherproofing and refined install/mounting options, delivering great
sound in any outdoor area or transitional space, porch, sunroom or deck.
The new Atrium Series offers five new models, including a smaller design
that blends better into the outdoor environment, with sonic improvements
specifically engineered for better outdoor performance. Plus, we’ve tightened the tolerances on all mating surfaces for even more outdoor reliability.
New Atrium Series Features
Speed-Lock™ Mounting System, for easy, secure one-handed
installations even in difficult locations. The greatly simplified
mounting procedure means fewer parts to “juggle.”
Anodized Aluminum Tweeter Domes With Rubber Surrounds
Injection Molded Mid-Range Cones With Rubber Surrounds,
either mineral-filled polypropylene or aerated polypropylene,
the same material used in our high-end LSi Series (depending
upon model), are newly re-designed for higher outdoor efficiency.
Broad Coverage Baffle Design, applied in our current Atriums
and which has been so well-received, has been improved
in the new Atrium Series.
Aluminum Grilles And Bracket, with stainless steel and brass
hardware: no rust, ever.
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).
Patented Water-Resistant PowerPort® Bass Venting
(on Atrium6 & Atrium8SDI) efficiently adds 3 dB of big,
realistic, musical bass output.
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.
Available In Durable, Weatherproof Black Or White Paintable Finishes.
