Precision Devices PD.185N02 - 18 inch 1100W Sub Bass Driver 8Ohm

The PD.185N02 has been designed to provide high fidelity, clean, undistorted, low frequency reproduction with the power handing and performance capabilities expected in pro audio. Very similar in characteristics to the PD.185N01, the PD.185N02 offers an increased BL force factor, over 30T/m, and a modified surround profile designed to limit the excursion of the cone while providing faster transient response. The unit also has a slightly higher power rating of 1100W (AES) and exhibits an average sensitivity of 98dB across its working bandwidth of 35Hz - 1kHz.

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.185N02 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. A large displacement dual suspension system combines with UK manufactured cone and surround to provide excellent linear control and mechanical stability with extremely low distortion and 45 mm peak to peak excursion before damage. Intended for use as a sub bass driver or woofer in bass reflex and horn loaded systems, the driver's versatility also allows it to be used well in closed box designs.

Features:

  • Lightweight neodymium motor system.
  • Heavy duty cast aluminium frame for increased rigidity.
  • Low distortion subwoofer.
  • Long driver excursion.
  • High BL factor in excess of 30 T/m.
  • Double suspension system.
  • Suitable for bass reflex or horn loaded designs but also works well in closed box applications.
