The newly-developed CoherentWave phasing plug assembly consistsof four die-cast annular aperturestructures of constant path length toprovide in-phase combining of diaphragm output at the driver's exit.This optimized configuration allowscoherent summation of energy up tomuch higher frequencies than previous designs, with an attendant increase in perceived high-frequencyclarity.

The new diaphragm design includesJBL's exclusive three-dimensionaldiamond pattern surround whichreduces membrane stresses in thediaphragm support structure andextends diaphragm life. The depth ofthe diamond pattern is closely controlled during the manufacturingprocess to provide predictable frequencies for the 2nd and 3rd normalresonance modes and for the basicsuspension resonance mode.

High-temperature voice coil former materials and adhesives enable the 2450H/J to handle extremely high powerlevels over extended periods of time. The voice coilsthemselves are identical to previous JBL models, so thatimpedance and network matching will be the same. Aftermanufacture, the frequency response of each driver istested for conformity to JBL's rigid performance standards.

The model 2450H/J is ruggedly constructed to withstand the rigors of fixed and transportable commercialapplications. All cast parts and tolerances are held to thesame levels traditionally associated with JBL designs.High-pressure press-fit assemblies combined with precisely machined interlocking parts assure extended resistance to mechanical shock. The JBL manufacturing process also permits the use of rim centered rather than pinmounted diaphragms, for instant interchangeability andease of field service.
