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.

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.

Perfect for our balcony, no crazy bass but they sound good and should not annoy neighbors.
