MALT Cross
In Beyma we face the problem of heat dissipation with a clear goal in mind: the speaker must deliver the best performance in the system in a consistent and reliable way, maximizing the total SPL and keeping it stable.

It is well known how the overall SPL of a system suffers a drop after some time working due to the power compression effect in the speakers. It is also known that normally the bigger the voice coil diameter the higher the power capacity, but this also means bigger motor structures to obtain high total output from the transducer.

The Maltcross cooling technology that we deliver to the Professional Audio market through our speakers, bring together several solutions to meet our goal; in one side allows the woofer to handle bigger rates of power with a given coil diameter, so we can think in smaller coil designs with smaller motor structure, reducing the weight but increasing the sensitivity and also keeping an adequate power handling figure for a target application, maintaining a total SPL finally that may be equivalent to a bigger size motor structure driver.

The Matcross technology is a forced convection circuit inside the heart of the driver that helps to lower the working temperature of the coil and also acts like a demodulation ring, linearizing the inductance of the transducer.
