The On-Stage SS7745 is an all-aluminum subwoofer-mounting speaker shaft with a pair of heavy-duty 1-3/8" endcaps, adjustable from 36" - 60", designed to connect full-range or mid-range speaker satellites to floor-positioned P.A. subwoofers.
How exciting can shafts for speakers be? Doing the job intended is about good enough. This is a fully decent product.
Works well. Could use a shim in my older subs (EV SXA180) to keep the pole perfectly upright. But no wobbling once installed, just a slight tilt (maybe 1/2 degree). Locks to desired length very securely.
