Upgraded to a ergonomic and stylish vented chassis design with sleek black motor system plating that offers improved thermal management and up to 10x corrosion resistance in harsh environments. The PD.1852/2 has been fully analysed and verified with our Klippel KA3 analyser system to ensure it meets the very highest standards of performance and reliability.
The premium choice for the most demanding of high performance, high power sub-bass applications. The PD.1852/2 provides powerful and accurate bass frequencies with minimal distortion and power compression.
An optimum choice for top of the range sub bass systems where the ability to take punishment in the most demanding applications is the ultimate selection criterion. Appropriate for applications as diverse as scoop bins, conventional reflex cabinets and horn loaded systems.
