Adjustable Subwoofer Attachment Shaft with Locking Adapter — Reversible 32.5–47 in Pole (Pack of 2)

This adjustable attachment shaft for subwoofers uses a manually activated ring to operate internal sliders that expand and eliminate the gap between the pole and the insert, cutting down wobble caused by wind, sound, or audience vibrations. The oversized activation ring lets you lock and unlock quickly and easily. Pole adjusts from 32.5 to 47 in height and is reversible. The result is a straight, stable speaker setup that provides reliable performance and a professional appearance.
