Beyma 18LEX1000Fe 2000W, 8 Ohm 18-inch Bass Woofer

The Beyma 18LEX1000Fe is a professional 18-inch loose subwoofer driver designed for powerful low-frequency reproduction in high-performance PA systems and custom speaker cabinets.

It delivers 1,000W RMS power handling and 2,000W program power at an 8-ohm nominal impedance. With a sensitivity of 98 dB, a 3.5-inch voice coil and an 11 mm Xmax, the driver produces strong, controlled bass while maintaining reliable performance at high output levels.

Beyma’s Maltcross cooling technology improves heat dissipation around the voice coil, allowing the driver to handle demanding professional applications with reduced power compression.
