Rediffusion used to manufacture and install PA systems: this may well have been the core part of one. I recall my ex-colleague Rupert Neve recounting anecdotes from his time there in the 1950s: he worked for Rediffusion before branching out on his own first with CQ Audio, then the Neve studio mixing desk business.

It was Rediffusion who supplied the PA systems for the South Bank Festival of Britain in 1951: I recall Rupert telling me of the amplifier spec, which was push-pull throughout like a Decola. The attached South Bank photo shows, to the left of the tree, a splendid array of a couple of dozen straight horn PA speakers.
