PD.123C01 - Bass Driver

  • Heavy duty cast aluminium frame for increased rigidity.
  • Low distortion.
  • Long driver excursion.
  • Suitable for bass reflex or band pass designs.


 

The PD.123C01 is the perfect choice for extended low-frequency response and high SPL applications from a nominal 12-inch driver. 

Ideal for bandpass applications and extended throw designs. The 123C01 also excels in compact two-way cabinets offering extended low frequency reproduction and smooth midrange. Easy to integrate with small format HF drivers utilising the woofers usable frequency range of 45Hz to 3.5kHz.

 


*2.83V. Half space response measured in a 975 Litre sealed Enclosure. Blue Line = fundamental 45° off-axis.

*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 (45 to 450Hz) Program 400Watts.
2. AES Recommended Practice.
3. Thiele - Small Parameters follow a 400 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.
