Beyma featured its PW series with new ceramic magnet system designs at Prolight + Sound 2012. The first to arrive are the 21” 21PW1400Fe and 18” 18PW1400Fe. Both are extended low frequency transducers designed for vented configurations, and both feature Beyma’s Malt Cross system, a new cooling system (patent pending) that lets the speakers to handle up to 2800 program power, reducing the losses due to power compression using a 4-inch double layer inner/outer voice coil.

The benefits in our design approach comes when we can balance more accurately the ratio between mass and inertia in a dynamic behavior of big moving parts, obtaining a better control in extreme mechanical displacements (Xdamage is 55mm). Thanks to that and to a carefully designed motor and suspension system through our MMSS technology, the total SPL of the system will be high, accurate and stable. The final result is extremely controlled transient response and low distortion (Xmax is ±10mm), high thermal and mechanical stability, high durability and a consistent performance in the life working period of these subwoofer loudspeakers. A new reference is born.
Completing our PM4 driver’s family, we introduce the WL4Fe, our first ceramic magnet compact line array driver. Thanks to our optimized design and the behavior of the PM4 diaphragm, this driver with mounted wave guide will deliver an excellent response to the high frequency way of line array applications while maintaining a competitive and more stable price. A recent new product using the PM4 diaphragm is the CD1014Fe, the “ferrite version” of CD1014Nd, a 1,4” exit driver with 1,75” voice coil (44,4 mm) and PM4 diaphragm, which confers a response with high sensitivity of 110 dB, natural tonal qualities and the stability which allows and excellent power handling (140 W program above 1,2 kHz). This is probably the best quality/price ratio in the market for a 1,4” exit compression driver.
Extending the G40 series, we have developed the ceramic magnet version of a 6” mid-bass driver in that range; the new 6G40Fe. Designed with FEA to optimize the magnetic flux in the gap, and with MMSS to achieve a linear behavior in the longer excursions, the unit delivers an excellent performance for mid-bass applications. It handles up to 340 W (program) with more than 94 dB of sensitivity (1w 1m). It also includes a demodulating ring in order to reduce the eddy currents, which helps to linearize the impedance response and to reduce the distortion. An excellent choice for line array applications.
Last but not least some units to be highlighted are the recently launched 12P80Fe and 15P80Fe. Two low-frequency speakers designed to deliver high efficiency with high linearity, low distortion and excellent SPL output. With sensitivities above 100 dB incorporating 4″ (100mm) voice coils with a program power handling of 1400 W and 1600 W respectively, and designed for optimal performance in high-efficiency multi-way systems, thanks to their sonic properties over a wide frequency band. The use of advanced materials and design tools such as the CONEX, carbon fiber and MMSS technology, allow these speakers to provide a sound performance of the highest quality for applications that demand it.
