Great looking, outdoor speakers, the sound quality is sufficient to get the party in full swing, easy to install.

Installed in outdoor bar / kitchen. They’re under cover but I wouldn’t put a non outdoor rated speaker outside, even under cover. It isn’t just the rain, it’s the dew and air temp that’s can play havoc with this sort of stuff. Nice sound from the speakers. Perhaps the atrium 5’s would have been better for bass but you can’t knock the sound from these at all. Got them hooked up to a Douk audio amp via a Sonos connect. Sound is really lovely and the speakers are a nice quality.

Whilst the box was not damaged the speaker grill on 1 speaker had a big dent.Good sound but disappointed that it was damaged.

Sehr starke Lautsprecher mit tollem Sound.

This is my second set of Polk Audio outdoors speakers. My first pair are the Atrium 6s, which are amazing and produce very clear and accurate sound (in my humble opinion). Recognizing that the Atrium 4s are smaller, they still produce very good sound. The mounting system that both speakers use make them very easy to install and wire, and the Atrium 4s worked right out of the box with no fuss. The bass reproduction is good, but not at the same level as the Atrium 6s. Nevertheless, they are quite good at filling small to medium spaces, and they very effectively filled my lower patio area with quality sound. As an aside, these are standard speakers and are not powered so you will need an amplifier or receiver to power them. Both my Atrium 4s and 6s seem very well sealed against the weather elements and they are both holding up very well. I can definitely recommend the Atrium 4s for outdoor installations.
