Sonos One Mid-Woofer Diaphragm Repair/ Replacement

Difficulty

Moderate

Steps

Time Required

10 minutes

Introduction

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.

Tools

Step 1

Disconnect all power cords.
Remove the rubber foot and plastic screw guard on the bottom of the device using a plastic opening tool.
Note: the rubber foot and plastic screw guard can be removed as one piece to make reassembly easier

Step 2

Remove the four 10mm Torx T10 screws from the bottom of the speaker.

Step 3

Remove the bottom cover by squeezing the protective cover slightly while pushing up with your fingers.

Step 4

The protective cover clip is very thin and deforms easily.
Remove the single 8mm Torx T10 screw and protective cover clip.

Step 5

Slide the protective cover upwards to remove.

Step 6

Use the pointed end of a spudger to remove the covers that hide the screws.
Remove the four 9mm Torx T8 screws from around the perimeter of the control panel.

Step 7

With the front of the unit facing you, lift the control panel up using your thumbs.
There's a ribbon cable attaching the control panel to the speaker so work slowly.

Step 8

Use a spudger to flip up the retaining flap on the control panel ribbon cable ZIF socket.
Pull the control panel ribbon cable out of its socket.

Step 9

Pull the control panel away from the speaker to separate.

Step 10

Remove the six 9mm Torx T8 screws from the motherboard panel.

Step 11

Using a plastic opening tool, separate the motherboard from the speaker.

Step 12

Using your thumb, disconnect the speaker cable from the motherboard.

Step 13

Disconnect the power adapter plug from the motherboard using your thumb.

Step 14

Using the pointed end of the spudger, disconnect the red, green, and yellow cables connecting the WiFi transmitter/receiver.

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.

Step 15

Remove the motherboard panel from the speaker housing.

Step 16

The woofer is highly magnetic, making removal of the metal screws sometimes difficult.
Remove the two 9mm Torx T8 screws from the power adapter plug.
Remove the power adapter receptacle from its housing slot.

Brilliant, incredibly helpful. Somehow the adapter had come out of its slot. All working now. Thanks!

Step 17

Disconnect the woofer cables.
If removing the tabs is difficult, the flat end of the spudger may be used to depress the middle tab and then the tab may be pulled to disconnect.

Step 18

Disconnect the cables from the tweeter.

This step is unnecessary unless you intend to remove the tweeter.

Step 19

Remove the four 10mm Torx T10 screws from the tweeter.
Remove the tweeter from the speaker housing.

Likewise, this step is also unnecessary if you just want to remove the woofer.

Step 20

My screws were T20
