These Polk audio outdoor speakers deliver exceptional sound anywhere. The compact Atrium 4 Outdoor Loudspeaker meets or exceeds military specs for environmental endurance. Its small size fits tight spots by the pool, on the deck, around the kitchen or filling the backyard with great sound. Easy-mount hardware lets you enjoy high-performance audio in every season, and durable, weatherproof black or white paintable finishes. For homeowners interested in outdoor entertaining, these outdoor pool speakers couple a 4 1/2" Dynamic Balance long-throw mineral-filled polypropylene cone with butyl rubber surround pumps out surprising bass, and a 3/4" anodized aluminum dome tweeter with neodymium magnet for smooth response. A steeply angled baffle maximizes mid- and high-frequency dispersion over large areas without sacrificing detail. As wired speakers for stereo or multi-zone setups, Atrium 4 uses the proprietary Speed-Lock system for one-handed installation; simply click, aim, and tighten. Polk All-Weather Certification means Atrium Speakers can effortlessly withstand the worst mother nature can dish out, whether it's extreme temps or heavy rains. Compact yet powerful, Atrium 4 offers award-winning Polk Audio sound, four-season durability and effortless placement—ideal for any music lover’s patio, garage or backyard.
