The flagship PD.24603BR embodies major advancements for Precision Devices driver technology and is the result of an intensive 24 month research and development phase. The perfect combination of elegant design and superior audio output, the PD.24603BR represents best-in-class performance for professional audio designers.
Incorporating an unconventional neodymium motor system design, driving a 6.08” high-power, copper voice coil with an incredible B/L force factor of 39 T/m. The unit is capable of handling 1800W (AES) (3600 W program power) and exhibits 98 dB sensitivity over its working band of 20 - 200 Hz. The vented, die-cast aluminium chassis design combines with motor and coil venting systems to efficiently maintain optimal operating temperatures, increasing reliability and minimising power compression effects. Featuring an optimised compliance, large displacement, suspension system in conjunction with straight-sided, ribbed cone geometry. This sub bass behemoth offers the benefits of ultra-mechanical control, perfect linear excursion and low harmonic distortion. Delivering unsurpassed levels of LF output, while remaining fast and articulate.
Tuned for use primarily in bass reflex enclosures from 150-220 litres, the PD.24603BR is also capable of performing admirably in other cabinet design formats.
