Weather is one thing that we can't control. That's why the QSC KS Subwoofer Cover is a neccesity for your QSC KS Subwoofers. When loading and unloading your audio equipment each week, they need to be protected from dust, moisture, and the elements. These speaker covers are padded, and feature a dustproof and water resistant cover specially designed to fit the QSC KS Series subwoofers.
