Polk Atrium4 All-Weather Outdoor Speakers


The Compact Atrium4 loudspeaker produces high-fidelity sound quality anywhere you want great sound. Its small size makes it ideal for tight, out-of-way installations.



Broad coverage baffle design, adapted and applied from our current Atrium design but with subtle improvements in the new Atrium Series. If you want to fill a large open outdoor space with big, full-range sound, the new Atrium Series has a more steeply-angled baffle design that maximises critical mid- and high-frequency dispersion over a large area, without sacrificing the detail.



Durable, mineral-filled polypropylene cabinet design, with moulded-in bracing, sounds like a real speaker (not an "outdoor speaker”), and survives years of seasonal changes, for truly great sound, no matter what the weather.
