❚ Voice Coil Cooling System
Pioneer’s Voice Coil Cooling System (VCCS)
brings added power to the world of audio
subwoofers. Strong solid bass requires electric juice to get it going.
Since the situation can get pretty hot, the heat has to go
somewhere. This is where VCCS technology steps in. As voice coil
temperatures rise, so does resistance. Unfortunately, increased
resistance affects the damping factor and creates distortion. VCCS
takes the heat away from the 4- or 2-layer voice coil using a heat-
resistant, highly conductive aluminium bobbin which enables
increased power and tonally accurate sound. Plus, extra slits in the
bobbin reduce eddy currents while radiating the heat, which further
lowers the temperature of the voice coil. Problem solved, thanks to
Pioneer technology.
