  • Unique Planar Wave Design 
  • Cost effective, high efficiency Neodymium magnet assembly
  • Perfect acoustical coupling of individual units to create virtually continuous line source
  • 112 dB sensitivity 1 W / 1 m
  • 1 kHz Crossover
  • Extended high frequency response up to 20 kHz

The BMS 4512 ND Planar wave driver radiates a coherent planar wave front form a rectangular piston without internal diffraction for superior dispertion control and high fidelity sound. This distinctive new transducer was engineered to work with 4-inch (4″ x 1“) rectangular throat waveguides providing extremely high sensitivity.

The 4512 ND is optimised for 10° vertical dispertion and allows a horizontal coverage from 60° to 120° depending on the waveguide used. The unique design of the 4512 ND planar wave driver allows perfect acoustical coupling of individual units to create virtually continuous line source.

The BMS annular diaphragm together with the cost effective, high efficiency Neodymium magnet assembly offers an economical solution for high performance line arrays.

 The ring diaphragm works similar as a wound 140 mm long ribbon diaphragm providing linear frequency response up tp 20 kHz. The unique planar wave phase plug provide a coherent planar wave front without internal diffraction.

70W AES compression driver, 1.75 διάφραγμα τιτανίου, 16Ω

The model 2426H is a professionalquality high frequency compressiondriver which incorporates JBL'stitanium diamond diaphragm. Thistitanium diamond structure combinesthe ruggedness of phenolic andcomposite-type diaphragms with theoutstanding frequency response offragile aluminum and exotic metaldiaphragms.

JBL's exclusive suspension, consistingof a three-dimensional diamondpattern, reduces bendingstresses in the diaphragm supportstructure. The depth of the diamondpattern is closely controlled toprovide predictable frequencies forthe 2nd and 3rd normal resonancemodes and for the basic suspensionresonance.

The mathematically determinedphasing plug consists of concentricexponential horns to minimize phasecancellations. Phasing plug, throat exittube and diaphragm assemblies areidentical to the previous model.

All cast parts and tolerances are held to the same levels traditionally associated with JBL designs. Additionally the press-fit assembly and interlocking parts assure greater resistance to the mechanical shock. Diaphragm assemblies are rim centered rather than pin mounted, for instant interchange ability and ease of field service.Mounting is provided for standard25 mm (1 in) three bolt pattern. The front snout may be removed(unscrewed) to allow standard 1 3/8" -18 screw mounting. Through holes for external attachment points are also provided. A machined ring of copper surrounds the pole piece to counteract the inductance of the voice coi1 at high frequencies. After manufacture, the frequency response of each driver is tested for conformity to rigid performance standards.

The 2426H is offered in an 8 ohm impedance, and the otherwise identical 2426J is offered in a 16 ohm impedance.

 

The 2426H features a removable flange to expose a 1 3/8“-18 snout for screw-on type horns.
