If, in the unlikely event your compression driver breaks down, it’s straightforward to replace it, using an official Celestion diaphragm repair kit. Check out the attached video for some key points on how to make the repair.
You can use the replacement diaphragm kit (shown in the video) to repair the CDX1-1745,
1746,
1730 and
1731.
However there are replacement kits available for most of Celestion’s extensive CDX range and the method of replacement in each case is very similar and just as straightforward.
Contact your Celestion vendor for more details on the CDX range and available replacement diaphragm kits and find a dealer here: https://celestion.com/where-to-buy/
