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 efficient 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.

* Half space response measured in a 950 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 (70 to 700 Hz) Program 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.
