Westminster Royal GR

Tannoy's flagship and the reason the rest of the range exists: a 380 mm Dual Concentric loaded into a 530-litre compound horn, 1395 mm tall and 980 mm wide, weighing 138 kg apiece. The horn takes the acoustic crossover down to 200 Hz and the sensitivity up to 99 dB, so it plays at realistic level on single-figure wattage and reaches 18 Hz. It needs a large room and a serious floor, and nothing else in the catalogue works like it.
