Exceptional sound anywhere you want it – really, anywhere. The compact Atrium® 4 Outdoor Loudspeaker meets or exceeds military specifications for environmental endurance. Its small size makes it ideal for tight, out-of-way installations: by the pool, next to the deck or patio, around the kitchen, tucked away in the family den, or filling the backyard with great sound. The easy to mount Atrium 4 will deliver high performance audio fall, winter, spring, and summer, bringing years of outdoor enjoyment. Available in durable, weatherproof black or white paintable finishes.
- 4 1/2" (11.43cm) Dynamic Balance®: Long-throw mineral-filled polypropylene cone driver with butyl rubber surround pumps out surprising bass response from a compact design.
- 3/4" (19mm) Dynamic Balance: Anodized aluminum dome tweeter with rubber surround and neodymium magnet for better power handling and smoother response.
- Broad coverage baffle design: Fills a large open outdoor space with big, full-range sound. The Atrium 4 has a more steeply-angled baffle design that maximizes critical mid-and high-frequency dispersion over a large area, without sacrificing detail.
- Speed-Lock® Mounting: The easiest, fastest, and safest of all mounting systems.
- 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.) 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.
