Citronic CASA-210BA Dual 10" 600W Active Subwoofer
The Citronic CASA-210BA is a Dual 10" 600W RMS Class-D Active Subwoofer with independent 2-channel XLR inputs and outputs, fixed DSP filtering, phase switch, flat/boost control and a 35mm pole mount socket — suitable for 2.1 mobile PA setups, fixed sound reinforcement installations and discreet subwoofer applications.
The Citronic CASA-210BA is a dual driver active subwoofer cabinet delivering 600W RMS from its onboard Class-D amplifier across twin 10" woofers — providing powerful, controlled low-frequency reinforcement for mobile PA systems, live sound setups and fixed installation applications. Constructed from 15mm MDF with a durable polyurea finish and fitted with an integral carry handle, the CASA-210BA is built for both regular gigging and permanent installation use.
Independent 2-Channel Input & Output for 2.1 System Configuration
The CASA-210BA features two independent balanced XLR/jack combo inputs and two balanced XLR outputs — one per channel — allowing the subwoofer to be integrated into a 2.1 system alongside two full-range speaker cabinets with independent signal paths for left and right channels. Each input has its own independent level control, giving complete flexibility over the sub content contribution from each channel independently — useful in asymmetric room setups or where different programme material is playing through each channel. The XLR outputs pass signal through to the full-range cabinets, keeping the signal chain clean and straightforward.
Fixed DSP Filtering & Flexible Control
Onboard fixed DSP accurately filters low frequencies to the Class-D amplifier section for optimised subwoofer performance without the need for external processing equipment. A variable frequency control allows the crossover point to be adjusted to suit the connected full-range speakers, a flat/boost switch provides tonal shaping for different programme material and environments, and a phase switch corrects time-alignment or out-of-phase situations between the subwoofer and full-range cabinets — ensuring the sub integrates cleanly with any PA system.
Versatile Positioning & Installation
The CASA-210BA can be positioned flat with a 35mm pole mount socket on top to accept a full-range speaker cabinet on a standard speaker pole, or stood upright for a smaller floor footprint in space-constrained environments. The narrow footprint and durable polyurea finish also make it an ideal choice for discreet fixed installation applications where a subwoofer needs to be positioned unobtrusively within a venue.
