Independent shopping perspective
The Korena take
The On-Stage SSA20M is a threaded adapter for replacing an existing 1 3/8-inch subwoofer socket. It is designed as a direct replacement for most socket mounts: remove the existing mount and install the adapter in its place. Its M20 thread connects the subwoofer to compatible speaker poles without wobble. It is also intended for use with the SS7746 Adjustable Subwoofer Shaft.
