I am working on a pair of BeoVox S80 loudspeakers. They are fine, but have just one issue: the midtown driver is not producing sound.
I already did some research and found a video by Texasound about this. One of the causes he describes is that the voice coil has come loose from the rubber dome. I checked that, and found it is also my issue.
In the process of repairing the mid-tone driver, I am almost done. The voice coil has been re-attached to the dome with epoxy glue. Now I have to glue the dome back to the driver.
Originally B&O glued the dome just on one point to the metal ring of the driver. This is on the side where the leads come out and where B&O attached a small strip of tape to the metal ring of the driver. (See picture) So in fact, the dome glues to this piece of tape. I also noticed that B&O’s original glue is still sticky, so it probably doesn’t completely dry up.
This final stage, raises 2 questions.
- What type of glue is best to use for glueing the dome to the tape on the metal ring of the mid-tone driver?
- How can I best make sure that while glue-ing, the dome is centered, so the voice coil does not scratch the sides?
