*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 (50 to 500 Hz) @ 400 Watts.
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.
*2.83V. Half space response measured in a 975 Litre sealed enclosure.
• Vented cast aluminium chassis for improved thermal control of voice coil.
• Optimised vented voice coil cools and reduces coil gap turbulence.
• Multi roll cone surround profile.
• High BL of 24.5 T/m.
The PD.123C001 oers excellent linear response well controlled down to 50Hz. It is
a very good solution for two way or multi way systems when a high BL and good
punch is required.
