BMS BMS4512NDH 4512 ND – 4″ Neodymium high-frequency Driver 80 W 16 Ohm

• 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.
