Description

The Citronic CASA-18B is a high-power passive subwoofer designed to add serious low-end punch to any PA system. Built from durable 15mm MDF with a textured paint finish, it combines strength with portability, weighing 30kg and fitted with dual side handles for easy transport. The front-loaded 18" driver with 3" voice coil delivers deep, controlled bass down to 45Hz with an impressive 600W RMS (1100W max) handling capacity. A protective steel grille shields the driver, while a 35mm top-hat socket allows pole-mounting of full-range cabinets. The rear panel offers Speakon inputs with link capability, while a built-in low-pass filter ensures optimal integration with tops. Delivering up to 127dB SPL, the CASA-18B provides a powerful bass foundation for live performances, DJs, and mobile sound systems. Perfectly matched with the CASA range of PA cabinets, it’s equally reliable in any demanding sound reinforcement setup.
