A New Transducer Paradigm
MM-FORCE redefines low-frequency design with an advanced moving magnet topology replacing the conventional moving-coil architecture for greater efficiency and control. From installed audio to automotive and immersive systems, MM-FORCE combines acoustic impact, mechanical control and Powersoft’s system-level expertise.

Building-Block Scalability
MM-FORCE is available in two models, designed to meet different integration and performance requirements: 8-inch and 10-inch. It gives manufacturers the freedom to scale low-frequency performance with a compact, modular building block. Its ultra-low-profile design makes it easy to integrate one or multiple units according to the desired acoustic output, cabinet format and installation constraints.
The square form factor helps optimize the use of available space, maximizing radiating surface while reducing wasted baffle area when multiple transducers are placed side by side. This modular approach enables flexible product architectures, from compact single-driver solutions to scalable multi-driver bass systems.

Engineered around uptime
Delivers strong low-frequency output from reduced enclosure volumes, enabling bass integration in space-constrained applications.
Moving magnet technology, stationary coil design, and high-efficiency amplification help reduce losses and improve energy transfer.
The inertially balanced architecture reduces vibration, making MM-FORCE suitable for walls, vehicles, furniture, and other sensitive installations.
The system is designed for precise diaphragm motion, supporting powerful bass with control, stability, and reduced mechanical stress.
