Precision Devices PD.CD1.5NR1 Precision Devices - Exporting Is Great the precision dna Precision Devices PD.CD1N Precision Devices Compression Driver Range - Out Now


  • Heavy-duty cast aluminium chassis for increased rigidity.
  • Smooth extended low-frequency response.
  • Suitable for bass reflex and bandpass applications.
  • Easy integration with 2" compression drivers.

*2.83V. Half space response measured in a 975 Litre sealed enclosure.


*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.

1. AES Standard (50 to 500 Hz) Program 1200 Watts.
2. AES Recommended Practice.
3. Thiele - Small Parameters follow a 600 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.
