PD.188

  • Heavy-duty cast aluminium chassis for increased rigidity.
  • Double suspension system.
  • A B/L in excess of 29 T/m.
  • Effective transducer in a variety of versatile applications.
  • Suitable for horn loaded or reflex designs.


*2.83V. Half space response measured in a 208 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 (40 to 400 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.
