To the G&G Sound, we know well that the quality audio is one of the most important elements of which account needs in the planning of our selfpowered loudspeakers. New adopted technology, furnished us by the Italian firm Powersoft, it allows to integrate amplifier and processor of signal inside the same loudspeakers. The whole series has been developed using the best materials and considering the real demands of the technicians and the services. The enclosures realized with plywood of birch, cut and perforated with numerical control machineries, introduces an elevated resistance. The amplifiers with feeding type switching are characterized by least dimensions, small weight (max 2,43 pounds) and elevated audio powers. The 24-bit 48 kHz DSP to be install on power amplifier have own inside different functional blocks as, equalization, crossover, dynamics, delay, etc., it is programmed through hardware connected to pc during the whole phase of planning. All the a coustic measures are made in condition of semispherical acoustic load, with radiant loudspeaker upward and microphone set to a meter by the acoustic center.
