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