Description
The Citronic CASA-210B is a dual driver passive subwoofer cabinet built for mobile and fixed sound reinforcement. Twin 10" (250mm) woofers sit in a front-loaded design that handles a combined 600W rms, giving you a punchy, rounded low end. The pair of drivers are wired in parallel through a low pass filter, so unwanted high and mid frequencies are removed before they reach the cones, leaving the sub to do its job cleanly.
Input comes from your amplifier via two SPK connectors, with a total impedance of 4 Ohms (8 Ohms per driver). The frequency response runs from 55Hz up to 2kHz, and the internal filter is a 120Hz low pass at 12dB per octave. Maximum power handling reaches 1200W, so there is headroom for busier work. The cabinet is made from 15mm MDF with a hard-wearing polyurea finish, and there is an integral carry handle to make moving it between jobs easier.
You can lay the CASA-210B flat and fit a full-range speaker on top using the 35mm pole mount socket, or stand it upright for a narrower footprint. That upright option, along with the shape of the cabinet, makes it a sensible choice for discreet installation where floor space is tight. At 690 x 480 x 305mm and 30kg, it is a solid unit that suits both touring rigs and permanent setups.

Frequently Asked
Is the CASA-210B passive or active?
It is a passive subwoofer, so it needs a separate amplifier. Input is via two SPK connectors wired in parallel through a low pass filter.
What is the impedance and power handling?
Total impedance is 4 Ohms, with each of the two drivers at 8 Ohms. It handles 600W rms and up to 1200W maximum.
Can I mount a speaker on top?
Yes. Lay the cabinet flat and use the 35mm pole mount socket to fit a full-range speaker above the sub.
What size are the drivers?
The cabinet holds two 10" (250mm) woofers in a front-loaded arrangement.
What is the crossover point?
There is an internal 120Hz low pass filter at 12dB per octave, so only low frequencies reach the woofers.
How heavy is the cabinet?
It weighs 30kg and measures 690 x 480 x 305mm, with an integral carry handle for moving it.
