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.
