Pro Audio Loudspeakers Designed with Innovative Heat Dissipation Technology

Jorge Serrano, the Director of R&D at Acustica Beyma in Valencia, Spain, discusses the innovation that has gone into developing the Maltcross technology for heat dissipation in Beyma professional loudspeakers

The Maltcross cooling technology that we deliver to the professional audio market through their speakers brings together several solutions to meet their goal; one side allows the woofer to handle bigger rates of power with a given coil diameter. This allows for Beyma to think of 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.

A very interesting podcast that addresses solving key problems in pro loudspeaker design.
