Precision Devices PD.185NR1

The PD.185NR1 is ideally suited to applications where high power handling, long excursion and perfect linearity is required. Ideal for bass reflex design cabinets. The robust mechanical design and construction makes this unit an ideal choice for fixed or touring applications. The optimised radial neodymium motor system allows more efficient management of the magnetic flux, forced air venting and rear aluminium base plate keeps the motors temperature under control and reduced power compression to a minimum. The unit features a 5-inch, high temperature, copper voice coil capable of handling 1400W (AES) the PD.185NR1 exhibits an average sensitivity of 96dB across its working band.
