They were not based on any existing cabinet design. Some time
before Wireless World (which was a great magazine at that time)

To build the horns, we first cut the profile in a piece of
plywood (hyperbolic IIRC), then used this to make a plaster
mould. This in turn was covered with several layers of the
glass fiber sheets and epoxy resin - a very messy affair.

They sounded very well, and were incredibly efficient.
