This guide is for the replacement of the woofer diaphragm for the Sonos One.
Important: Accessing the internals of the Sonos One will void the factory warranty and make the unit rejected for factory repair, even if warranty is expired.

These terminals were covered with a big glob of wax on my motherboard, so I managed to remove the woofer without detaching the motherboard from the speaker housing. So, this step is optional, and really isn’t necessary.
The red and green need to be swapped around when reassembling it. Don't go off the picture above.

Any suggestion on where to buy these woofers (in Europe/Belgium)?
@mglowa Any idea where to buy a replacement woofer pictured above? Or what to look for, an equivalent perhaps?
This is the link to the replacement woofer that I used to repair my Sonos One in August 2024: https://www.aliexpress.com/item/10050071...
"SOTAMIA 1Pcs 3.5 Inch Midrange Woofer Speaker 4 Ohm 35W Bass Loudspeaker Aluminum Basin Hifi Music Sound Speaker Audio For SONOS"
56mm high,
75mm distance between adjacent screw holes
105mm diagonal distance between non-adjacent screw holes
97mm width of outer casing
Great guide - replaced the subwoofer using the part above. A few things to note:
Step 13: my unit didn't have an power adapter plug; wires soldered onto board
Step 14:my unit had hardened glue spread on the yellow/red/green cables making removal impossible.
There was no need to remove the tweeter to replace the woofer (steps 18/19).
