I was delighted when Terry Miles brought this beauty along to the Canterbury Audio Jumble in March 2005 and allowed me to photograph. It is a very early ex-BBC Research Department prototype LS3/5 which was given to him by Spencer Hughes. It was fantastic to see and handle this speaker which would certainly have been used by Spencer and by Dudley Harwood during the development of the LS3/5a. It is interesting to note the blocked hole in the froint panel which suggests some tests were done to make a Bass-Reflex enclosure before the design settled on a sealed cabinet. Thanks Terry!
