Precision Devices PD.124NR1
The PD.124NR1 is intended as a high power mid bass driver in multiway systems. The unit can also be used as a dedicated woofer 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 800W (AES). The PD.154NR1 exhibits an average sensitivity of 97dB across its working band and will produce an SPL of 126.5 dB in an 45Ltr ported enclosure tuned to 60Hz.
