Intended as a high power bass / mid driver in traditional two way or multi way systems designs. The PD.124NR1's lower FS offers the ability for lower cabinet tuning and porting in reflex designs. The unit can also be used as a dedicated bass driver in bass reflex and horn loaded designs.

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 4-inch, high temperature, CCAW voice coil capable of handling 1000W (AES).

* 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 (55 to 550 Hz) Program 1000 Watts.

2. AES Recommended Practice.

3. Thiele - Small Parameters follow a 800 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.
