Very high performance custom audio system developed in team by Sottovoce Audio (design and electroacoustics) and ATM (electronics).

The customer aimed for a high demanding loudspeaker trio, with high definition and, at the same time, high sound pressure levels.

The design is formed by three “main monitor” loudspeaker cabinets (1×5″ high freq. + 2×6,5″ mid + 2×10″ low). Their response is extended in the very low range by a pair of 18″ subwoofers (on L/R channels), previously owned by the customer.
