Providing outstanding high-power bass and sub bass in systems that demand the best possible low frequency response. The PD.186/3 is a popular choice for horn-loaded applications where it can deliver full low-end at high SPL with superior power compression performance thanks to the huge copper area and breathing arrangement of the voice coil. Ideal for three-way direct radiating systems where the powerful bass comes into its own.
The PD.186/3 is well suited for use with the PD.121/2 alongside PD 1” and 2” compression drivers where its double suspension system allows it to thrive.

Notes
** 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 verified by Klippel LSI measurement.
4. 2.83V. Half space response measured in a 975 Litre sealed enclosure.
Please note that frequency response measurements are supplied for comparison purposes only and are not a measure of the low frequency performance which may be achievable in a fully optimised system.
