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


  • Heavy-duty cast aluminium chassis for increased rigidity.
  • Mid range transducer.
  • Synthetic loaded paper cone optimised for minimum delayed resonances.
  • Lightweight neodymium magnet.
  • Suitable for direct radiating or horn loaded mid/high applications.

*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 (60 to 100 Hz) Program 600 Watts.
2. AES Recommended Practice.
3. Thiele - Small Parameters follow a 300 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.
