Review: Pair them with a good Amp and you’re in for a treat! - These really are quite a remarkable pair of speakers when paired with a good quality amplifier! I originally powered them with a Fosi HT4S and they sounded ok but pretty rough in the midrange. Then I tried a Wiim Amp and they sounded much better, nice and refined and balanced but I just had a feeling they could go further. Then I bit the bullet and got a second hand Arcam SA10 and that really brought them to life! Amazing clarity and such great warmth from the Arcam. They are lacking in bass but as they’re the smallest in the range that’s to be expected. I’ve already decided to upgrade to the Atrium 6 and move the 4s to a quieter part of the garden. All in all a fantastic pair of speakers! Great build quality, fantastic sound and easy to fit. Power them with a good quality amplifier and you’re in for a real treat!
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.

## Questions & Answers

**Q: We do not have a covered deck. Could these outdoor speakers be totally exposed to the outdoor element?**
A: I have installed these speakers totally exposed and they have lasted several years the grills might become rusty looking depending on the area you're in

**Q: Are these compatible with Alexa/Echo Dot?**
A: These are not Bluetooth speakers so they will not work directly with Echos or Dots and need to be powered by an audio receiver. You can however, use an RCA or Bluetooth connection between an Echo or Dot and the reciever and stream to the speakers.

**Q: Is it two packs of pairs being a total of 4 speakers?**
A: No the 4 is for the size and model, there is only 2 speakers in the box!
These are Great Speakers!!!

**Q: Is it easy to be operated? I hope it will be not too hard to do that...**
A: …Were very easy to set up, and I just connected to the amplifier and then to the record player.…You can buy this amplifier if you are a lack of it.https://www.amazon.com/Bluetooth-Amplifier-Receiver-Integrated-Audio/dp/B07L3F5QQ7

### ⭐⭐⭐⭐⭐ Good sound outside, weatherproof including heavy rain!
*by J***. on 13 October 2021*

I’ve got these mounted up outside and I’ve got great sound. I was nervous about how waterproof they would be but they’ve had no problems even after some incredibly heavy rain in London over the summer. They install easily with well thought out brackets that Mount quickly with the speakers clipping on easily. I think it’ll be very easy for me to bring them in over winter.
