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


  • Heavy-duty cast aluminium chassis for increased rigidity.
  • Power compression 2dB at rated power.
  • A B/L in excess of 37 T/m.
  • Double suspension system.
  • Suitable for horn loaded or bass reflex designs.

*2.83V. Half space response measured in a 234 Litre vented 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 (30 to 300 Hz) Program 2000 Watts.
2. AES Recommended Practice.
3. Thiele - Small Parameters follow a 1000 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.
