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.
