The originals had Parmeko dual concentric drivers. I think they date
from about the early '50s. The tweeter was added after FM started and some
home listeners were hearing things you couldn't on the LSU/10 which I
think cut off at about 10kHz which was fine for AM radio then. The amps
were either Leak or SoundSales. Cabinets were made by Lockwood who later
moved on from just being cabinet makers to produce their own designs for
recording studios, etc.

Lockwood of Harrow were actually coffin makers. They build
a range of excellent infinite baffle enclosures for Tannoy 15inch
and 12inch dual concentrics, for studio use. The Major was the
most impressive of these.

They used the same gold handles on speaker cabs and coffins:-)
