Yorx SB309 YORX SB309 Heavy Duty Professional Speaker Stand

Once you mount the speaker on the SB309, it will support it, reducing the lift load. You can then turn the telescoping knob and the SB309 will assist in smoothly raising and lowering heavy loads with minimal effort. For heavier loads–up to 60kg–you will be surprised by how little effort it takes to raise the speaker to the right height.
