Polk Audio Atrium 4 Outdoor Speakers (Pair, White)

The Atrium 4 is quick and easy to install with Polk's Speed Lock Mounting system.

Designed for exceptional sound anywhere you need it, the compact Atrium 4 Outdoor Loudspeaker meets or exceeds military specifications for environmental endurance. Its small size makes it ideal for tight, out-of-the-way installations, such as by the pool, next to the deck or patio, around the kitchen, or tucked away in the family den, filling the backyard with great sound. The easy-to-mount Atrium 4 will deliver high-performance audio year-round, bringing years of outdoor enjoyment. It is available in durable, weatherproof black or white paintable finishes.

If you're seeking great high-fidelity sound and a speaker that can be placed even in the most exposed locations without worry, the Atrium 4 is the perfect choice. Its high-quality components deliver impressively big sound from this small, unobtrusive loudspeaker, and its compact size makes it ideal for tight, out-of-the-way installations.

The Atrium 4 features Polk's Dynamic Balance technology, which analyzes a speaker's microscopic behavior while in motion using laser interferometry to select the ideal combination of materials, geometry, and construction techniques to "tune out" unwanted resonance for pure, distortion-free deep bass. Klippel Transducer Optimization further optimizes the transducer's motor structure, voice coil alignment, and suspension for longer excursion and greater linearity, delivering the best possible performance even at the most extreme listening levels.

Polk's proprietary Speed-Lock Mounting System allows for easy, safe one-handed installations, even in difficult locations. The simplified mounting procedure eliminates the need for "juggling" at the top of a ladder. The new bracket also has a 45-degree down angle, providing a simple, elegant solution for optimal speaker positioning.
