ONE NEW TANNOY tweeter / HF, suits and will fit most 6" & 8" & 10" drivers, if it looks like this, and its a 6" 8" 10" driver ... it should fit.If in doubt, ask me, I will look up on the Tannoy spare parts list.
Tannoy has consolidated all previous models into one HF for 6" 8" 10", and another for most 12" & 15".
Ferrofluid included & already fitted.
