Atrium 55
The Speaker For All Seasons
Indoors or out, multi-zone or second room, Polk Audio’s Atrium
All-Application Loudspeakers are versatile enough to deliver
great sound anywhere your clients want it.
The rugged Atrium Series meets or exceeds stringent industry and military
specifications for full exposure to the elements for years of reliable high
performance sound anywhere in and around a home.
Polymer driver cones with butyl rubber surrounds housed in a
watertight ABS cabinet stand up to Mother Nature and yet deliver great
bass response. The dome tweeter (with a small but powerful neodymium
magnet) broadly distributes high frequencies to cover large areas with
high fidelity Polk Audio sound.
The Self-Powered, indoor-only Atrium 45p gives you the flexibility to
take advantage of the “Multi-Room” receiver function, bringing high
performance sound and remote volume control to extra rooms without
adding extra amplifiers. (Simply run a set of speaker wires (or line level
cables) from the main receiver, preamp or amp to the Atrium 45p for
incredibly convenient sound.)
Put incredible sound…anywhere, with the versatile Polk Audio
Atrium Series of All-Application Loudspeakers.
