Yeah, I thought the button legends were a bit odd.
Equally funny is watching the whole thing jump in the fixture.

Are these the speakers? http://www.44bx.com/tannoy/gold.html#anchor2238478

If so then they should be fairly easily repaired. A good repair shop will remove
the surround and the spider (probably with acetone) and they can re-attach the
winding or rewind if necessary.

Where I am in the most remote capital in the world we have a repair shop who
could do it http://www.shortfuse.net.au/ He is frequently asked to perform this
type of repair on Altec, Goodmans, Wharfedale etc.
