Saving Tannoy Sensys 6' DC speakers


Recently I got a set of small Tannoy DC speakers with x-over filters without cabinets.
I did not know what model# they were, so I had to find what they are.
Here is what I found:
 

Here you see that the speaker units are from the Sensys series.

Another Sensys box for sale on the internet.

The speaker units were broken and the cones aluminium foil was teared.
In order to save the speakers I had to remove the foil completely from the bass cones,
rebuild the bass cones and coat the cones with hardening coating and re-glue them back into the chassis.
Also I had to change the x-overs as the accompanying supertweeters were broken as well.

This is what I got when I put them into new cabinets:

The sound is surpisingly good with the newly assembled x-over.

I think I have saved the speakers from a certain death.
