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


  • Vented cast aluminium chassis for improved thermal control of voice coil.
  • Optimised vented voice coil cools and reduces turbulence in the coil gap.
  • M-roll cone surround profile.
  • Ribbed cone.
  • High BL of 24.19 T/m.


The PD.153C001 offers excellent linear response well controlled down to 40Hz. It is a very good solution for two way or multi way systems when high BL and good punch is required. The PD.153C001 can also be used in a compact sub application. Works well in conjunction with PD.CD.1.5 compression driver.


* 2.83V. Half space response measured in a 960 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.

** Distortion is measured at 10% of the rated power (AES Standard).

1. AES Standard (40 to 400 Hz) Program 400 Watts.

2. AES Recommended Practice.

3. Thiele - Small Parameters follow a 450 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.
