PD.184C01 - Bass Driver

  • Heavy duty cast aluminium frame for increased rigidity.
  • Low distortion.
  • Suitable for bass reflex or closed box designs but also works well in horn loaded designs.

The PD.184C01 utilises our new chassis design and has been engineered using a fully optimised cone and surround to improve linearity and tonal character. These changes bring the PD.184C01 to the forefront for improved, Hi-Fi like performance coupled with Pro Audio power handling and reliability.

The PD.184C01 performance characteristics can be optimised by reflex loading. The excellent definition and response speed at the lowest audio frequencies make this drive unit eminently suitable as the bass component in monitoring systems.

This versatile driver is equally at home in traditional Horn Loaded applications offering tight punch / defined bass reproduction across its working band.


*2.83V. Half space response measured in a 975 Litre sealed Enclosure. Blue Line = fundamental 45° off-axis.

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.

1. AES Standard (40 to 400Hz) Program 700 Watts.
2. AES Recommended Practice.
3. Thiele - Small Parameters follow a 700 Watt preconditioning period.

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.
