Professional 8 ohm 15ND930 speaker

Professional 8 ohm speaker 15ND930

The 15ND930 is a low frequency neodymium extended range high power loudspeaker, meeting the most stringent requirements of high quality professional loudspeakers. The high level of performance and sound quality have been achieved by exploiting the most advanced technologies available today. Thanks to its versatility, the 15ND930 can be used in compact 2-way SLR enclosures with a 1.4 "compression driver, in multiway systems and in high load sub woofers up to 70 liters (compact SLR, bandpass and loaded configurations Neodymium Magnet assembly ensures high flux concentration, low power compression and excellent heat exchange, as the external magnet configuration is significantly more efficient than the traditional under pole magnet topology. translates into high levels of force factor and power management with an optimal weight / power ratio. Direct contact between the large heat sink and the basket, together with the magnetic structure, represent a fundamental improvement in thermal connection and heat dissipation. Therefore, the power handling capabilities are increased and the power compression reduced. The curved cone to profile deep, created from a special high strength wood pulp, it has been designed to obtain the best possible linearity within its frequency range. The cone frame, made of a linen material, is highly resistant to aging and fatigue. The in-house developed cone treatment is a moisture repellent and significantly dampens the resonances of the bell mode. The 75 mm (3 inch) copper wound edge voice coil assembly is wound on a sturdy fiberglass former to improve force transmission and power handling. The already low distortion and sound quality are further enhanced by the Double Demodulating Rings (DDR) which flatten impedance and phase with constant power transfer. A special coating applied to both the top and rear plates makes the 15ND930 much more resistant to the corrosive effects of salts and oxidation.
