Built for Versatility

The KS112's cabinet is constructed of premium birch. High-quality, low-noise casters allow you to easily position and reposition the sub to fit the specific audio of the moment.

The sub incorporates two M20 threaded pole receptacles for a wobble-free pole-mounted connection—either vertically or horizontally—to a threaded speaker pole (sold separately). KS112s can also be stacked horizontally: its four rubber feet perfectly fit into the four cups at the top of a second unit.
