The Atrium Series Loudspeaker is the ultimate in flexibility, reliability and high fidelity sound quality for indoors or the great outdoors. Atrium speakers enable music to be enjoyed virtually anywhere—including the pool, hot tub and outdoor kitchen.

Like all high quality Polk speakers, the dome tweeters and polymer drivers in all Atrium series speakers are both Dynamic Balance and Klippel Optimized. Dynamic Balance allows analysis of the operation of the component on a microscopic level, reducing or eliminating artifacts that color the sound. Klippel Optimization ensures the speaker will perform well at both low and high volumes levels. Polk Atrium speakers provide excellent damping and bass response while resisting deterioration. Polk's Atrium Series speakers meet or exceed military specifications for environmental endurance for ultraviolet, salt-fog exposure and immersion.
