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.

Beautiful, fabulous sound. All over a great product and value for every penny
Absolutely stunned, they are fabulous. I have read loads of good reviews about these speakers and a few negative. All I can say is they are absolutely fabulous. I have them in my semi large garden and they fill it up (2500sqr/ft) . Got them connected with my Denon Cleol and the sound is great, clear and plenty of base. Oh and they are loud even though my Apm is pulling 35w at 8 Ohms, any louder and I would have security at my door. To me they beat Bose hands down. Highly highly Recommended

Very good sound quality for the price. Paired with a sub provide well balanced sound with a bit of eq. Without the sub the bass are a bit weak…

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.

Se escuchan muy bien, son el reemplazo de mis bocinas antiguas para Atmos.

Mounted these on my back deck to replace an old pair of speakers that had failed. Very nice clean sound with good bass for their size.

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.
