The flagship of the line, the Atrium8sdi has a unique, patented* Single/Dual Input Switch that combined with its ingenious dual tweeter array enables you to use the Atrium8sdi as either a single high performance stereo loudspeaker, or the left-or-right speaker in a high performance stereo pair. And you can use it practically anywhere, because the Atrium8sdi also has special military spec waterproofing features, including our patented water-resistant PowerPort bass venting.
6 1/2" (16.51cm) long-throw aerated polypropylene cone driver with butyl rubber surround pumps out surprising bass response from a compact design.
Two 1" (24.5mm) anodized aluminum dome tweeters with rubber surrounds and neodymium magnets offer better power handling, smoother response and greater accuracy. Dual tweeter array with stereo tweeter aiming creates excellent imaging, whether used as a single stereo speaker, or as half of a stereo pair.
Dual Voice Coil woofer for greater efficiency and power handling.
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.
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.
Polk Audio 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 Audio All-Weather speakers.
Aluminum grilles and bracket, with stainless steel and brass hardware: No rust. Ever.
Gold plated 5-way binding posts for the most secure, efficient hookups.
Available in durable, weatherproof black or white paintable finishes.
