Atrium4 (W)
(Home Speakers - Outdoor Speakers)

The Atrium 4's high quality driver and tweeter deliver an impressively big sound from a very small package. Yet its compact size makes it ideal for tight, out-of-way installations. By the pool, around the kitchen, tucked away in the family den or filling the backyard with great sound. Like our bigger Atriums, the Atrium4 is built rugged to deliver years of great performance fall, winter, spring and summer.
