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.
Review: 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…

## 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

*by M***X on 17 September 2025*

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…

### ⭐⭐⭐⭐⭐ Pair them with a good Amp and you’re in for a treat!
*by M***N on 19 April 2026*

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!
