*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 (70 to 700 Hz) @ 450 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.
Half space response measured in a 950 Litre sealed enclosure.
• Radial neodymium motor structure.
• Vented cast aluminium chassis for improved thermal control of voice coil.
• Forced air cooling vented voice coil gap.
• Aluminium demodulation ring.
• 3” High temperature CCAW voice coil
• Rear aluminium heat sink.
The PD.103NR1 is intended for use as a high power mid range driver in multiway
systems. The optimised radial neodymium motor system allows more ecient
management of the magnetic flux. Forced air venting and rear aluminium base
plate keeps the motor temperature under control and reduces power compression
to a minimum. The unit features a 3-inch, high temperature, CCAW voice coil
capable of handling 700W (AES). The PD.103NR1 exhibits an average sensitivity of
100dB across its working band and will produce an SPL of 126 dB in a 15Ltr sealed
enclosure.
