QSC KS212C Subwoofer

The cardioid design focuses low-frequency energy toward your audience rather than letting it spill backward onto the stage. This helps clean up the sound on stage, reducing muddy bass buildup and feedback issues for performers.

At 88.5 lbs, it is substantial, but the integrated heavy-duty casters make it much easier to roll across flat surfaces. For loading into a vehicle, you will likely want a second person to help lift it safely.

Yes, the KS212C is designed to integrate into most professional sound systems. It features standard XLR/1/4-inch combo inputs and XLR loop-thru outputs, making it compatible with almost any active speaker setup.

The dual 12-inch configuration offers a punchier, tighter bass response that is often preferred for live music and clarity. While it may not hit the extreme sub-bass frequencies of a large 18-inch woofer, it provides a more compact footprint without sacrificing significant output.

Yes, the enclosure is built from 15mm birch plywood, which is a professional standard for durability. It is designed to withstand the rigors of transport and frequent setup in demanding live environments.

It runs on standard AC power. Because it is a high-output 3600-watt unit, ensure you are plugging it into a reliable power source or circuit that can handle the draw without voltage drops.
