About 1980, I built two loudspeakers from a kit of parts, comprising the bass and treble speaker units, and bitumen damping sheets and wadding, provided by Wilmslow Audio. The cabinets I made from plywood cut by a wood supply shop in Rochester.
These served me well, but a few years ago i decided to demolish them, but kept the driver units.
An attempt at rebuilding the speakers,
but arriving at the wrong dimensions,
as I had lost the book
with the construction plans,
I only got as far as making
the front baffles
The Salvaged driver units
So I decided to contact Wilmslow Audio,
and see if they had the plans of the Loudspeaker,
and fortunately they were able to come up
with the original article from HI-FI for pleasure magazine
I worked out a cutting plan
for the reconstructed loudspeakers
I was able to use the existing
incorrectly dimensioned baffles,
and carefully cut and spliced them
to the correct dimensions.
The hole for the port was still too large,
but I found a way of reducing its diameter
