GENERAL DESCRIPTION
This dual loudspeaker incorporates a 12” bass transducer, featuring a 3” voice coil diameter, edgewound aluminium
ribbon wire, and a concentrically mounted 2” compression driver into an integrated voice coil gap magnet system. This
design achieves high efficiency, smooth frequency response, low distortion, reduces phasing problems in the crossover
region, and simplifies enclosure design.
