Since its release in 2013, Powersoft’s M-Force linear transducer has explored greater possibilities in infra-bass, reaching well below the conventional frequency range. Now its Italian develper is pushing its boundaries still further with the introduction of the M-Force 301P02 and its associated reference designs.

Powersoft M-Force EDMSub‘Although the original M-Force has had a great life cycle, we knew that the time was right for our patented infra-bass technology to take another leap forward,’ says Powersoft OEM solutions Sales Manager, Giacomo Previ. ‘This new iteration of the M-Force linear motor transducer comes equipped with high-voltage and high-current connectors, and a range of internal electromechanical improvements. We’re excited to share the new M-Force with the world, and we can’t wait to see what our fellow audio innovators will be able to create using this new technology.’

The M-Force moving magnet linear motor structure allows extraordinary levels of efficiency and reliability, making it the perfect choice for high-efficiency, high-SPL low-frequency sound reinforcement. The application of M-Force technology is now easier than ever, thanks to the 301P02 – a complete solution that enables all levels of speaker builders to incorporate the M-Force into any design with absolute confidence, both in self-powered and passive configurations.

The motor is factory matched to a purpose-built diaphragm, through a newly designed coupling and a lightweight chassis that also improves thermal dissipation, while the addition of a front spider further stabilises the design.

The new reference designs have been created by Powersoft to help users increase the SPL capabilities of systems, whether they are system builders, sound system owners or installation professionals. All of the designs are free and come along with a cut list and presets that can be managed using the company’s ArmoníaPlus software.

‘Self-powered configurations rely on the M-Drive, a purpose-built amplifier module designed to deliver the juice to the M-Force. We recommend powering double 30-inch passive designs using the mighty X4L,’ explains Powersoft’s Francesco Fanicchi.

As the soon-to-be-released reference designs illustrate, Powersoft’s M-Force 301P02 is ideally suited to a variety of seemingly disparate applications: The EDM Sub bandpass design features two M-Force 301P02 transducers, which can be built both as a self-powered or passive infra-sub, driven either by an M-Drive amplifier module coupled with a DSPL ETH or an X4L amplifier platform respectively. When powered by an X4L, the sub can be connected to a Dante network. The design has been optimised for producing ultra-high SPL down to 18Hz, making the EDM Sub r an infra add-on to install or touring sound reinforcement system. The four available presets ensure ample coverage for different music programmes – Standard, Punch, Infra and a Cardioid version Standard.

The DV Sub is a bandpass cabinet loaded with the M-Force 301P02 transducer for subwoofer applications. The design has been optimised for producing very high SPL down to 28Hz in a very compact package, making the DV Sub an upgrade for an existing subwoofer, virtually eliminating non-linear distortions. Two presets are available to squeeze the most out of this box – Standard and Punch each available to accommodate cardioid configurations.

The CineSub is a hybrid transmission line cabinet loaded with the M-Force 301P02 transducer for infra and subwoofer applications. The design has been optimised for producing low distortion and high SPL from 16Hz to 120Hz, as per the Dolby and THX recommendations. Thanks to this high SPL, a single unit can replace four double 18-inch speakers with a better frequency extension and capability for cinema sound systems and high-end home theatre installations. The modular design can be used in both single and double cabinet configuration, and both presets are available for linear and minimum phase set-ups.
