Westminster GR
This magnificent 530 litre compound horn loudspeaker is a true statement of the art of acoustic reproduction in the home, blending class-leading power handling, real-world dynamics and musical articulation like no other speaker available today. The design sets a new benchmark for high performance music reproduction and owes much of its evolution to TANNOY’s Kingdom Royal development project. The new 380 mm (15 inch Dual Concentric driver is a natural but significant evolution of the classic 15 inch Dual, improving on every aspect of its performance both technically and subjectively. Within the Westminster Royal GR cabinet, the new driver exceeds an 18 Hz to 27 kHz frequency response while boasting 99 dB efficiency and 700watt peak power handling.
Key to the Westminster Royal GR Driver is revised material for the main 15 inch cone and a new 50 mm (2 inch diaphragm for the HF compression driver. The LF/MF cone material remains a paper-pulp base with fibres introduced into the mix to improve the stiffness to weight ratio. While previous flagship Duals were stiffened with natural capoc fibres, the Gold Reference Duals integrate a bespoke TANNOY synthetic fibre that delivers more uniformed mechanical integrity across the entire surface area of the cone. The result is effortless LF performance with outstanding speed and dynamic attack.
At the heart of the Westminster Royal GR Dual, the new 2 inch compression driver uses an aluminium-magnesium alloy dome heat treated to TANNOY’s exacting specifications. The diaphragm is terminated with a Mylar surround, delivering a technically and subjectively significant upgrade over the previous Prestige HF units. Delivering exceptional clarity and articulation throughout the HF range the new unit gives Westminster Royal GR even greater naturalness and presence.
The massive Westminster Royal GR crossover is meticulously hand-made by TANNOY engineers and comprises some of the finest audio components available today. TANNOY’s bespoke ICW ClarityCap MR capacitors, low loss laminated core inductors and thick-film resistors are hard-wired into the crossover with silver plated cable and high-silver content solder.
The glorious Westminster Royal GR cabinet is hand built from the finest birch plywood by TANNOY’s most experience cabinet makers, each cabinet weighing close to 140 kg when finished. The complex, compound horn design and curved front baffle allow the 15 inch Dual to ‘breath’ like no other Prestige model, delivering truly real-world dynamics and musical integrity. The luxury oiled-wood walnut veneer on panels and inlays, the gold trim and return of the classic TANNOY lightning strike logo exude the regal class of bespoke furniture.
With its new 15 inch Dual, DCT crossover and new terminal panel featuring the latest WBT NextGen WBT-0703 speaker posts, the Westminster Royal GR delivers musical engagement with the same breath-taking scale as its visual splendour. With TANNOY’s High Frequency Power Switch for fine tuning HF output and a matching woven-cloth grille, the Westminster Royal GR can be integrated into a wide range of rooms and decor. The Westminster Royal GR is an effortlessly capable loudspeaker that honours the decades of Dual Concentric technology but also of TANNOY the brand. The Westminster Royal GR is set to become a true TANNOY classic.
