Precision Devices PD.186/2 18" Driver 8 OHMS (PD186 MK2) PD.186 Mk2 700W

Designed to provide outstanding high power bass and sub bass, suitable for all systems demanding the best possible low frequency response.

A popular choice for horn loaded applications when the PD.186/2's full low end can deliver extremely high SPLs. Ideal for three-way direct radiating systems where the powerful bass comes into its own.

Well suited for use with PD. 121 and 1' / 2' compression drivers in direct radiating/horn loaded systems where the double suspension system allows it to thrive in the demanding touring sector.

  • Brand new 18" chassis design
  • Heavy duty cast aluminium frame for increased rigidity
  • Capable of dissipating tremendous heat build up when driven in concert conditions
  • 110 oz ceramic magnet
  • Huge copper area and breathing arrangement of the voice coil ensures superior power compression performance
  • Double suspension system maintaining a pure piston action for the moving mass and provides additional durability against the rigours of life on the road

*1 Power compression is the reduction of sensitivity at the specified power. Higher power ratings do not necessarily give a proportionate increase in SPL therefore the maximum SPL of the driver may significantly exceed that of other manufacturers with high power ratings.

** Distortion is measured at 10% of the rated power (AES Standard).

  • 1. AES Standard (40 to 400 Hz) Program 1400 Watts.
  • 2. AES Recommended Practice.


  • 3. Thiele - Small Parameters follow a 700 Watt preconditioning period.
