NMF SERIES

Near and Mid Field applications tailored High End Transducers by BEYMA.

Top quality parts

Top sonic properties thanks to the use of the best materials: carbon fiber cones with high rigidity for pistonic behaviour, unique Beyma QUATTRO voice coil for a high force factor to better control the moving mass, cast aluminium frames, electro coated metal parts to protect against humidity and age, Bimax spiders and high resistance NBR surrounds for high linear and stable behaviour. All these parts working together result in a consistent and robust performance even at very demanding conditions and long working cycles.

Transparency

The use of the latest simulation software delivers extremely linear behaviour in the long excursion of the woofers optimizing the motor structure. The magnetic circuit gives our exclusive QUATTRO voice coil a more controlled excursion within the linear range, therefore extending the dynamic range. The suspension system has also been carefully designed and optimized, with geometry and materials tailored for high damping and excursion control, avoiding common non-linearities and unwanted resonances on similar basic soft suspension types.

Geometric

Controlled directivity

Careful geometric design of membrane, dust cap and density for appropriate damping has been developed in order to obtain the most linear response possible, taking special care of the off axis response, for a controlled acoustic dispersion up to the crossover region.

Unmatched performace

Maltcross is a patented technology developed in-house that is at the core of the best professional low frequency drivers developed by Beyma. This smart feature provides a demodulating ring effect balancing the inductance versus excursion and allows a superlative cooling circuit where the air flows inside the airgap towards the voice coil in turbulent mode. Reduction in temperature and demodulation provide less power compression, higher SPL and less distortion at low frequencies.

Maltcross

Straightforward implementation

All these design features allow an engineer to work with and obtain a cabinet that can work from the very low end up to the crossover frequency with the high frequency device, within an extremely linear response, controlled excursion, damped unwanted resonance modes and extended and smooth breakup behavior for a friendly crossover design.

LEX

LEX Frames

Exclusive die cast aluminium LEX design frames, optimized in design with advanced Finite Element Method software offer a differential visual imprint in the drivers as well as optimized mechanical properties and an efficient work in the heat dissipation, thanks to the special air circuit specially designed to interchange the air between the air gap area and the outside.
