Concerto One, Concerto Two (1999-2000)

Concerto One and Two were conceived as purist audiophile loudspeakers for primarily two channel operation. Proven drivers, high quality real wood cabinets and skilfully implemented crossovers created two systems with neutral tonal balance, precise, stable imaging and a high level of musicality. Both systems utilised a 25mm fabric dome tweeter and 130mm doped paper cone bass/midrange units. These were integrated into a two-way format in the Concerto One, while Concerto Two was a more sophisticated three-way system. Both systems featured twin gold plated input terminals for bi-wiring or bi-amping and attractive substantial plinths as standard.
