The German pdf looks like it has some pertinent information, but I don't know how to do translation on a PDF.

Wires are tight and nothing rattles. All protruding pieces of film cut with

Then you can use the speakers with either the old grille cloth or with
a beautiful, new refer.
In the cover of the speaker, there are four or six Velcro pads. This Velcro pads
hold the cover to the speaker. Fix using the tacker the opposite

The placement of the cover in the reverse order as the decrease.
We hope you will change the
Films much success!

What a palava talk about complicated, blimey! never seen anything like it before, you need a perfect memory to follow that lot, no wonder they cost a fortune. My diaphragms would cost about a fiver and only take a half hour to replace at the most you wouldn't need any tools apart from a screwdriver, and a pair of scissors.I'm very glad my diaphragms are simple to make and fix. Doing all that would give me a stroke, and the accidents that could happen probably would, and would cost me an arm and a leg. Whereas my diaphragm would only cost a small hair in comparison. Lucky me.
