The black M20 Speaker Cabinet Adapter from On-Stage allows you to help upgrade your subwoofers by replacing the existing 1 3/8" sockets with the SSA20M threaded speaker adapter. It is designed to be a direct replacement for most socket mounts and all you have to do is simply remove and replace. M20 threading helps provide a rock-solid, wobble-free connection between the subwoofer and compatible speaker poles. This Speaker Cabinet Adapter is suitable for use with the SS7746 Adjustable Subwoofer Shaft (sold separately).
