18LEX1200Fe– Low frequency transducer

The Beyma 18LEX1200Fe is a high-power, low-distortion 18-inch subwoofer engineered for demanding professional bass applications. It features Beyma’s exclusive Malt Cross® cooling system to reduce power compression losses and ensure stable output at high levels, combined with a high sensitivity of 97 dB at 1 W/1 m. An FEA-optimised ceramic magnetic circuit, aluminium demodulating ring, ultra-low air noise design, and optimised linear behaviour deliver clean and controlled low frequency performance. The weatherproof treated cone, double silicone spider, and robust 4-inch DUO double layer in and out copper voice coil support extended controlled displacement of ±11 mm Xmax and a 48 mm peak-to-peak excursion, making it ideal for direct radiation and band-pass subwoofer applications.
