The BMS 4510ND 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 4510ND 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 4510ND planar wave driver allows perfect acoustical coupling of individual units to create virtually continuous line source. The driver contains a high energy neodymium magnet system and a unique annular ring diaphragm. 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.
