The On-Stage SS7747 Crank-Up Subwoofer Attachment Shaft features an integrated crank-operated mechanism that provides assistive power, making it safe and ergonomic for one person to raise and lower a heavy speaker. This shaft mounts to the top of a subwoofer cabinet to support speakers with standard pole-mount sockets, without using a separate floor stand. The mounting pole's M20 threading at the base connects to subs with an M20-threaded socket, a connection method that greatly reduces tilt and wobble. The shaft's height adjusts to accommodate a variety of applications and locks in place to ensure reliable positioning.

On-Stage SS7747 Crank-Up Subwoofer Shaft Features:

  • Crank system supplies leverage for safely raising and lowering a mounted speaker.
  • Crank handle folds down when not in use.
  • Speaker pole and adapter can fit speakers with either 1 3/8" or 1 1/2" mounting sockets.
  • M20-threaded connection of the base to the subwoofer greatly reduces tilt and wobble.
