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 the bigger the voice coil diameter the lower the power compression and the higher the power capacity, but this also means bigger motor structures to obtain high sensitivity from the transducer.
The latest cooling technology that we deliver to the Professional Audio market through our new 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.
Products like the 18PW1400Fe, or the unique 12MC500 are designed following that concept; models that even with a ceramic magnet structure, feature high sensitivity, an increased power capacity and performance comparable to bigger coil designs with neodymium motor structures.
