BMB CSW-112A Active Subwoofer

The BMB CSW-112A is a 12-inch active subwoofer designed for home karaoke and audio setups. It integrates a 308mm cone driver with a 65mm voice coil and a built-in amplifier. The bass reflex enclosure uses a Four Triangle design to spread low-frequency energy quickly. It suits users who want simplified installation with integrated amplification.

Upgrade from passive subwoofers

This active model replaces a separate passive subwoofer plus external power amplifier combination. The jump is worthwhile when rack space is limited or when you want volume, crossover and phase controls on the cabinet itself. It removes the need to match amplifier power to driver impedance manually. Buyers who need multiple drivers in a single enclosure should look elsewhere.

Line-level input constraints

Connectivity is limited to one RCA and one XLR input for line-level signals only. The amplifier delivers 300W RMS, 600W maximum and 1200W peak power consumption. Frequency response spans 31Hz to 200Hz at minus 10dB. Systems requiring speaker-level inputs, wireless streaming or additional output channels cannot be accommodated.

Questions about this item

How much floor space do the 410mm x 400mm x 440mm dimensions need?

The cabinet measures 410 mm high, 400 mm wide and 440 mm deep, so allow at least that footprint plus a few centimetres around the rear bass-reflex ports for airflow.

Which cable do I plug into the single RCA or XLR input for the first connection?

Use either the RCA or the XLR jack — both accept a line-level signal — then set the volume, crossover and phase controls on the rear panel before powering on.

When should the 65 mm voice-coil driver be checked or replaced?

The 12-inch cone with its 65 mm voice coil is built for continuous 300 W RMS use; inspect the surround and spider only if output drops or distortion appears after heavy karaoke sessions.
