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
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.

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.
