Review: Rather good, actually - 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.
Review: Damaged on delivery - Whilst the box was not damaged the speaker grill on 1 speaker had a big dent. Good sound but disappointed that it was damaged.

## Features

- Atrium series speakers exceed baseline industrial and military specifications for environmental endurance
- Anodized aluminum tweeter domes with rubber surrounds are absolutely immune to the elements, offer better power handling and smooth response
- Tweeter phase cap smooths the frequency response from 12kHz up to 20kHz, the last audible octave
- Broad coverage baffle design fills a large open outdoor space with big, full-range sound
- Speed-lock mounting system for easy, safe one-handed installations even in difficult locations
- 5 years parts and labor
- A more steeply-angled baffle maximizes critical mid- and high-frequency dispersion over a large area with out sacrificing detail

### ⭐⭐⭐⭐⭐ Tenían que ser Polk.
*by R***H on 29 April 2025*

Las compré para ponerlas como surround en mi AVR, tal vez hasta estén sobradas para eso. Antes, las probé como Segunda Zona y me gustó el sonido; en algún momento sustituiré también mis surround traseras por este modelo. Las volvería a comprar para una segunda zona para ambientar el jardín o en el comedor.
