BL 2446H Compression Driver 4" Titanium Diaph-8 Ohms100 watts continuous program at 500 Hz
The model 2446H/J is a professional quality high-frequency compression driver that incorporates JBLís newly developed Coherent Wave phasing plug as well as a pure titanium diaphragm with radial ribs and patented three-dimensional diamond pattern suspension.
The Coherent Wave phasing plug assembly consists of four die-cast annular aperture structures of constant path length to provide m-phase combining of diaphragm output at the driverís exit. This optimized configuration allows coherent summation of acoustical power up to much higher frequencies than afforded by earlier designs.
The diaphragm design includes JBLís exclusive three-dimensional diamond pattern surround1 which reduces membrane stresses in the diaphragm support structure and extends diaphragm life. The depth of the diamond pattern is closely controlled during the manufacturing process to provide predictable frequencies for the 2nd and 3rd normal resonance modes and for the basic suspension resonance mode. The diaphragm also incorporates a series of embossed radial reinforcing ribs that increase diaphragm stiffness. This diaphragm, when combined with the Coherent Wave phasing plug, increases the 2446H/Jís output in the 5 kHz to 20 kHz range.
High temperature voice coil former materials and adhesives enable the 2446H/J to handle extremely high power levels over extended periods of time. The voice coils themselves are identical to previous JBL models, so that impedance and network matching will be the same. After manufacture, the frequency response of each driver is tested for conformity to JBLís rigid performance standards. The model 2446H/J is ruggedly constructed to withstand the rigors of both fixed and transportable commercial applications. All cast parts and machined tolerances are held to the same levels traditionally associated with JBL designs. The JBL manufacturing process also permits the use of rim centered rather than pin mounted diaphragms, for instant interchangeability and ease of field service.
