The new 18PW1400Fe is one of the first extended low-frequency transducers designed by Beyma featuring the exclusive MaltCross® system, the latest advanced cooling system (patent pending) which allows the speakers to handle high power musical programs while maintaining an exceptionally constant SPL and liable response for the whole life of the speaker. It has been conceived for delivering the maximum performance in a vented or band-pass subwoofer system, featuring the most advanced technologies and materials Beyma is currently using
The MaltCross system is a new low noise forced convection circuit designed to make an effective heat transfer from the voice coil, allowing the system to handle high power while maintaining very low power compression loses. The benefit results in high total SPL from the system. Developed with careful electromagnetic design and tested mechanical behaviour for obtaining a balanced response from a device that will work with high power electrical inputs and large displacements. Features an excellent behaviour thanks to exclusive MMSS technology, an exclusive design technique that combines Finite Element Analysis, the NonLinear Parameters and other Beyma engineering tools to provide a symmetrical and linear behaviour. The materials and constitutive parts include the most advanced ones available in the market: aluminium demodulating ring; conex spider for a stable withstand of power in long term operation while maintaining the parameters of the speaker inside correct tolerances; waterproof cone; DUO double layer inner/outer voice coil and many more.
