However I got a bit of a brainwave and thought about going a step further and breaking up an old Sonos 1 speaker and possibly turning it into a WiFi speaker?
I’m a complete novice so don’t know if it’s even possible but more than willing to give it a bash and try.

I've done a few experiments with a raspberry pi 3a (£20, has WiFi) and Volumio (open source Sonos equivalent) with a mono amp.
It worked but I got a lot of noise on the speaker, from both the switch mode power supplies and the pi itself. The power requirement of the pi is not insignificant (0.5-2A), so it will need a mains connection. Its also recommended that the amp is powered seperately, unless you use the Roberts as an amp in which you're still stuck with the problem of how to power the pi with a module that can handle up to 2A and is not noisy.
You will get the same functionality as the sonos , and probably more, by installing Kodi on your phone and a Bluetooth module in the roberts, and simply pair the two.
Hope this helps
