        Beyma 12G40 Low Frequency Transducer

         

        The Beyma 12G40 is a robust 12-inch woofer designed for use in low-frequency speaker systems where efficiency, control, and durability are essential. Featuring a 3” copper voice coil wound on a polymide fiber glass former, this transducer handles 500 W AES (1,000 W program) power while delivering a sensitivity of 97 dB at 1W/1m. With a frequency response ranging from 45 Hz to 4,000 Hz, the 12G40 is ideal for full-range or subwoofer applications. It supports controlled excursion with an Xmax of ±7 mm and a 28 mm peak-to-peak excursion limit. The high mechanical compliance (206 µm/N) and optimized suspension result in smooth, punchy bass even at high power levels. Its efficient design fits bass-reflex enclosures from 20 to 70 liters, offering great versatility in sound reinforcement systems. Weighing 7.1 kg with a modest depth of 133 mm, the 12G40 delivers powerful performance in compact and portable cabinet designs.
