ClearSonic now offers a 12” height extender for its popular panels. The AX12 is perfect for those who need panels to stand 78” or higher. Each extender comes with “H” channel and hinge, and easily snaps to the top of existing panel sections. Complete systems will still fold “accordion style” even with the addition of height extenders. The AX12 is a single extension section so you can purchase just the right amount for your Sound Shield system.
