Utilising a 300 mm (12 inch) Gold Reference Dual Concentric driver housed in a beautifully designed, oiled walnut cabinet, provides the opportunity for music lovers to own an exclusive and high performance loudspeaker from the world-famous TANNOY Brand. GRF uses the initials of the company’s founder, Guy R Fountain, who started the company in London in 1926.

The GRF is 12 inch Dual Concentric with its signature PepperPot WaveGuide, Alnico motor system and HF compression driver delivers a superbly dynamic overall presentation with fast, accurate bass and a fluid and open midrange. With 90 years of experience, TANNOY’s GRF  driver boasts an incredible 560 watt peak power while offering over 95 dB efficiency.

The crossover design utilises extremely high quality components in a minimalist design ensuring the shortest possible signal path to the driver and providing flawless musical reproduction. Featuring TANNOY-specification ICW ClarityCap MR capacitors, low loss laminated core inductors and thick-film resistors, the entire crossover is Deep Cryogenically Treated as a whole unit. The process has allowed the GRF 90 to achieve unparalleled gains in resolution and deliver an even more natural and cohesive sound.

Minimising cabinet resonance, the bespoke birch plywood cabinetry is extensively braced internally and the twin rear port is engineered to reduce low frequency turbulence. Meticulous hand finishing and time-honoured traditional craftsmanship are evident in the timeless beauty of the oiled walnut veneers and cabinet detail. Gold anodised machined metal trims, intricately detailed with TANNOY’s nostalgic lightning strike logo complement the overall stunning appearance of the loudspeaker.
