The 15MC500's 500 W AES power handling and 98 dB sensitivity enable it to deliver clear and dynamic sound output, making it suitable for demanding audio applications. Its 2.5" copper wire voice coil enhances thermal stability, contributing to consistent performance over time. The Maltcross cooling system effectively dissipates heat, reducing power compression and maintaining consistent output during prolonged use. An aluminum demodulating ring is incorporated to minimize distortion, resulting in cleaner sound reproduction. The driver features an Xmax of ±8 mm, allowing for extended linear cone movement and deeper bass response without distortion. Its weatherproof cone, treated on both sides, enhances durability and resistance to environmental factors, making it suitable for both indoor and outdoor applications. With a peak-to-peak excursion before damage of 40 mm, the 15MC500 can withstand significant mechanical stress, ensuring longevity even under high-demand conditions. Optimized for use in 2-way or 3-way PA systems and line arrays, this transducer offers versatility and high performance for professional audio setups.​

At Beyma, the challenge of heat dissipation is met with a clear objective: ensuring our speakers consistently deliver optimal performance within the system, maximizing total sound pressure level (SPL) and maintaining stability.​

It's widely recognized that a system's overall SPL decreases over time due to power compression effects in the speakers. Typically, larger voice coil diameters correlate with higher power capacity; however, this also necessitates bigger motor structures to achieve high total output from the transducer.​

Beyma's Maltcross cooling technology presents multiple solutions to achieve this goal. It enables the woofer to handle higher power levels with a given coil diameter, allowing for designs with smaller coils and motor structures. This reduction in size decreases weight, increases sensitivity, and maintains adequate power handling for specific applications, resulting in a total SPL comparable to that of drivers with larger motor structures.

Maltcross technology incorporates a forced convection circuit within the driver's core, effectively lowering the coil's operating temperature. Additionally, it functions as a demodulation ring, linearizing the transducer's inductance.
