The PD.185N01 is a versatile drive unit intended for use as a sub bass driver or woofer component that offers outstanding imaging, clean, undistorted, high fidelity sound coupled with pro audio power handling and performance. Although intended for use in bass reflex and closed box designs the unit also performs well in horn loaded applications.

Featuring an FEA optimised, compact neodymium motor system configuration that allows more efficient management of the electromagnetic flux and greatly reduced stray magnetic fields. The PD.185N01 is able to provide the same power handling capabilities as much larger ferrite-based motor systems with the added benefit of greatly reduced weight. The motor system configuration and rear vent plate design have been developed in conjunction to allow effective heat dissipation and airflow around the 5", in-house wound, voice coil which aids power handling and reduces power compression effects. Power handling is rated at 1000 W (AES) with an average sensitivity of 98 dB across the driver's working bandwidth of 35 Hz - 1 kHz. High quality, UK manufactured cone and surround combine with a large displacement, dual suspension system that provides excellent linear control and mechanical stability, allowing 45 mm peak to peak excursion before damage. The materials have also been carefully selected to provide optimum high fidelity audio reproduction.
