![]() Power Capacity1: 70 W continuous program above 800 Hz 100 W continuous Program above 1.2 kHz. ![]() ![]() Minimum Impedance: 5 ohms (H), 9 ohms (J) 5 kHz.Nominal Impedance: 2426H - 8 ohms 2426J - 16 ohms.The front snout may be removed (unscrewed) to allow standard 1 3/8” - 18 screw mounting. Mounting is provided for standard 25 mm (1 in) three bolt pattern. Diaphragm assemblies are rim centered rather than pin mounted, for instant interchangeability and ease of field service. Additionally the press-fit assembly and interlocking parts assure greater resistance to the mechanical shock. Phasing plug, throat exit tube and diaphragm assemblies are identical to the previous model.Īll cast parts and tolerances are held to the same levels traditionally associated with JBL designs. The mathematically determined phasing plug consists of concentric exponential horns to minimize phase cancellations. The depth of the diamond pattern is closely controlled to provide predictable frequencies for the 2nd and 3rd normal resonance modes and for the basic suspension resonance. JBL’s exclusive suspension1, consisting of a three-dimensional diamond pattern, reduces bending stresses in the diaphragm support structure. This titanium diamond structure combines the ruggedness of phenolic and composite-type diaphragms with the outstanding frequency response of fragile aluminum and exotic metal diaphragms. The model 2426H is a professional quality high frequency compression driver which incorporates JBL's titanium diamond diaphragm.
