The 250 mm (10 inch) Gold Reference Dual, unique to the Turnberry GR, uses a new paper pulp cone material with HE twin roll fabric surround and 1.3 in aluminium-magnesium alloy dome tweeter with Tulip WaveGuide. The low frequency cone is fitted with a new 50 mm (2 inch) edge wound voice coil. This latest evolution of the 250 mm (10 inch) Dual brings an even more thrilling and dynamic performance than its well-regarded predecessor.
The high power crossover is hand-built on a dedicated crossover board using the finest sounding components and full Deep Cryogenically Treated to improve crystal structure of the conductor throughout the circuit. The result is a rich and articulate sound with remarkable sound staging and all the cohesive musicality of a true point source transducer. The Turnberry GR’s High Frequency power controls can tailor the listening experience without introducing any potential distortion than can result of using an amplifier’s ‘tone’ controls.
The Turnberry GR cabinet is hand built from the finest plywood using traditional joinery methods to ensure that attention to detail and unique styling go hand in hand. A distributed port design for exemplary LF response from the 85 litre enclosure, the cabinet is finished in Prestige oiled real walnut wood veneer and complimented with solid walnut trim and edging, machined metal trim and adjustable HF power.
Capable of handling peak input power of up to 340 watts and boasting prodigious 91 dB efficiency, the Turnberry GR has the power and authority of much larger and more affluent loudspeakers. It is detailed, dynamic and outstandingly articulate sound with all the musical cohesion inherent with the Dual Concentric driver. Turnberry GR offers the bespoke cabinetry and remarkable performance of TANNOY’s Prestige series, yet costs no more than a typical mass produced loudspeaker.
