The Citronic CASA-10BA active PA subwoofer features a Class D amplifier and a 10-inch low-frequency driver, delivering 300 W RMS. The 15 mm MDF cabinet has a steel protective grille, two side carry handles and a 35 mm socket for a speaker stand.

Balanced stereo XLR inputs and outputs allow connection to active speakers, while the high-pass-filtered XLR outputs make it easy to connect active full-range speakers. The phase switch helps prevent sound cancellation and align timing in systems with multiple speakers.
