With the introduction of the VTX Line Array Series, JBL is also unveiling the D2 Dual Driver.
The D2 Dual-Diaphragm Dual-Voice-Coil Compression Driver is designed to overcome the limitations of conventional compression driver technology: limited high frequency extension due to mass of the diaphragm and voice coil, and distortion characteristics that arise due to dome breakup modes. Merging two compression drivers into a single transducer with a single acoustical output, the D2 Dual Driver utilizes two voice coils, each with its own polymer, annular diaphragm, its own magnet assembly, and its own specialized phasing plug. Instead of the large and ‘heavy’ single voice coil metal dome diaphragm of conventional compression drivers, D2 is driven by two voice coils, two motive “forces” instead of one, acoustically connected to a single exit chamber.
Compared to a conventional system, the D2 has double the number of voice coils and more than double the power handling, but with a 30 percent reduction in weight, JBL assures. The power handling of the three D2 drivers used in the VTX V25 are each 200 watts per AES standard.
