SECTION 4 : VERTEC® DP SERIES TRANSDUCERS
2408H High Frequency Compression Driver
JBL’s 2408H features a lightweight neodymium magnet structure, annular polymer diaphragm and a 1” exit. Coupled to a proprietary waveguide engineered to be part of the system’s thermal-transfer mechanism, it is designed to deliver crystal-clear sound with superb dynamic range.The 2408H is an 8 Ohm device.Two are included in each VT4887ADP system.
2168H-1 Low Frequency Loudspeaker
The 2168H-1 is an 8” transducer engineered with JBL’s patented Differential Drive® technology.These low frequency drivers dramatically reduce driver weight while greatly enhancing all critical performance parameters: frequency response, power output, and distortion. Differential Drive technology features a unique design with heat sinks integrated into the cast aluminum frame for a highly improved performance to weight ratio.The dual voice coil design places the neodymium magnets inside the voice coil assembly, completing the magnetic circuit without the heavy surrounding steel structure of conventional drivers. 8 Ohm device.
