My B&W AM1 speakers have started to ‘crackle’, is it likely the Sonos Amp has overpowered them and blown the drivers? Thanks

It is fine as long as the volume ccntrol is in responsible hands. And even this issue that can be addressed by setting the volume levels for the Amp to 50% in the Sonos app. Until you hear from the service centre, I suggest you do this.

If these speakers are used outdoors and are not close to the listening areas - that is the bigger potential problem in the long term. Sound levels drop rapidly with distance for speakers outdoors and to address this issue you may be running them too loud.

Yes, AMP will support two pairs of AM1’s wired in parallel.

Wiring speakers is similar to wiring lamps. You can keep adding lamps until the circuit limit is reached. An individual lamp draws its power and is not aware of the others.

We don’t know exactly how the speaker failed. It’s possible that there was a manufacturing defect or that your average level was too high. It’s easy enough to determine this by inspecting the failed speaker.

The outside “room” is rather large and if you were attempting to be assertive out there, you may have been running the level too high. Assigning safe speaker power levels, unfortunately, is not an exact science. It’s typically more marketing than science. If you buy a “50W” speaker and use a 25W amplifier, safety is not guaranteed.
