Active Karaoke Subwoofer

The BMB CSW-110A is a powered 12-inch subwoofer built for home karaoke systems. Its active design integrates a 500 W maximum amplifier so no external power amp is required. A Four Triangle Bass Reflex enclosure spreads low frequencies quickly to help vocal clarity. The unit suits living-room setups that need strong, self-contained bass.

Buyers needing pro balanced inputs

XLR and RCA sockets give installers flexible connection choices for mixers or consumer receivers. Volume, crossover and phase controls let the user tune output to the room. Shoppers who want wireless streaming, multi-channel home-theatre decoding or a passive cabinet for their own amplifier should consider other categories.

500 W maximum power with 33 Hz low-frequency reach

The amplifier delivers 250 W RMS and peaks at 1000 W for dynamic karaoke tracks. Frequency response extends to 33 Hz at minus 10 dB, providing deep foundation for vocals and effects. A 275 mm cone with a 50 mm voice coil handles the load. This power and depth spec is the primary figure to match against your venue size.

Questions about this item

What type of audio source outputs do I need to connect the CSW-110A using its RCA or XLR input connectors?

You need a mixer, amplifier or karaoke processor that provides either an unbalanced RCA line-level output or a balanced XLR line-level output to feed the subwoofer's two input connectors.

Will the 33 Hz to 200 Hz frequency range of the CSW-110A blend with satellite speakers that only reproduce sound above 200 Hz?

The subwoofer covers 33 Hz to 200 Hz, so satellites that start at 200 Hz or higher will hand off cleanly; use the crossover control to match the exact handover point.

How can I verify the 500 W maximum output is performing correctly after I set the volume, crossover and phase controls?

Play bass-heavy material at a moderate level and confirm the 275 mm cone moves smoothly without distortion; the phase switch should tighten low-end impact when aligned with your satellites.
