The cabinet borrows technology from Formula One racing cars in that it is fashioned from carbon Fibre composite. The curved form with no straight lines resembles a musical instrument and unlike conventional speaker systems has no internal damping at all. The cabinet is empty, as Morel deliberately designed it to vibrate with the drive units and use this energy as part of the reproduced sound. The all important midrange frequencies are handled by a rather remarkable 6” drive unit fitted with the new Morel carbon Fibre /Rohacell sandwich cone. This unit when connected without a crossover is able to reproduce a full range sound from 40Hz up to 15kHz alone. The final specification is a remarkable 20-22,000 Hz (40-18,000 Hz ±1.5 dB).
