Vintage Tannoy 15" Concentric LS Speaker


Need assistance in calculating enclosure dimensions. I do not know the speaker data required for optimum size. Thank you for any help. These drivers are in excellent condition and sound amazingly good even without a cabinet.

I forgot to add that I have the crossovers which are in an enclosed metal box, also in superb condition. On the speaker it states "Type LSU/HF/15L.
