Help Identify These TANNOY GRF's


Hi all,

I recently inherited these Tannoy GRF speakers which have been in the family since new.

Can you please help identify the drivers and crossovers?

Any assistance is greatly appreciated.

Hi
Tannoy made 3 types of GRF speakers - GRF Rectangular, GRF Corner Horn and GRF Pro.
These are Tannoy GRF Rectangular Speakers. The drivers are 15" Monitor Red's. The Reds preceded the Monitor Gold's and have a 15 ohm input impedance. You need to bear this in mind when selecting a power amplifier.
check out Hans Hiberlink site for more info.
Tannoy GFR Rectangler Red's 15 ohms. Mid 1960's as the drivers have black dustcaps, the earlier 1960's have orange dustcaps. Great family heirloom. To the right buyer, can fetch 7K-9K. Hope you keep them.
Thanks everyone for the information. I do not have any audio equipment to run them.
