Polk Audio Atrium 8 SDI Outdoor Speaker
Description
The Polk Audio Atrium 8 SDI is the flagship model in Polk’s renowned Atrium outdoor speaker series, designed to deliver powerful, room-filling sound in outdoor environments while offering exceptional installation flexibility. Unlike conventional outdoor speakers, the Atrium 8 SDI features a unique Single/Dual Input (SDI) design that allows it to function either as a high-performance stereo speaker from a single unit or as a dedicated left or right channel speaker in a traditional stereo setup. Whether installed on a patio, terrace, balcony, garden, poolside area, or outdoor entertainment zone, the Atrium 8 SDI delivers premium indoor-quality sound with rugged all-weather durability.
Equipped with a 6.5-inch Dynamic Balance® polypropylene woofer, dual 1-inch anodized aluminum dome tweeters, and Polk’s patented PowerPort® bass venting technology, the Atrium 8 SDI produces deep, impactful bass, crystal-clear vocals, and expansive sound dispersion. Its weather-resistant enclosure, rust-proof hardware, and Speed-Lock™ mounting system ensure reliable year-round performance even in harsh outdoor conditions.
