The Atrium 5 is a passive two-way outdoor speaker with a 5-inch polypropylene woofer and an aluminum dome tweeter. Polk rates it down to 60 Hz, so it reaches lower than most small outdoor speakers, and its 90 dB sensitivity means a modest amp can drive it. The sealed all-weather cabinet resists moisture, salt and UV, and the included bracket aims the speaker where you want it. It suits patios, decks and covered porches where you want indoor-style sound outside. Against cheaper outdoor speakers it gives fuller bass and a more balanced midrange; it is not a Bluetooth speaker and needs a separate amplifier.

Owners of the Atrium line generally report solid outdoor sound and good weather resistance over multiple seasons. Complaints tend to focus on the need for separate amplification and on bass that is adequate rather than deep.
