@tony1954 What are those stands? Can you make them ring by tapping them lightly with a screwdriver or wrench?
6 foot triangle works but how far from the front wall (the wall behind the speakers)
So glad to see you invest in the life's work of Billy Woodman. That driver was I think his first SL driver design, came after the midrange. The tweeter in that pair is a miniature version of the ATC mid design.. All hand built in the Cotswolds, not too far from the old Jaguar factory.
