Description

The Citronic CASA-15B is a passive 15" subwoofer cabinet delivering deep, reliable bass reinforcement for professional sound systems. Its rugged 15mm MDF enclosure, finished with durable textured paint, is compact yet powerful, handling 500W RMS (900W max) through its high-flex 15" driver with 3" voice coil. With a frequency response down to 50Hz and a maximum SPL of 123.5dB, it delivers warmth and punch for live bands, DJs, and installations. Dual Speakon connectors on the rear panel allow secure amplifier input and link-through to additional speakers. A built-in low-pass filter ensures smooth crossover with tops, while a steel front grille protects the driver. Designed for portability, it features side handles and a 35mm top-hat mount for easy pairing with PA cabinets. Compact dimensions and robust performance make the CASA-15B a versatile choice for anyone requiring serious low-end reinforcement in a portable, road-ready format.
