Edit March 2020 Ok guys, I have been using these for a few months and there is a problem, the stands are very smooth metal, the plastic bushings are very hard smooth plastic. When you finish you gig and lower the speaker, the amount of torque required to lock the stands is crazy. You get the stand expanding in the stand bag etc, at the last gig I had to take the stand home fully extended because the 6mm wing bolt that locks the upper pole lost its thread. I have dismantled the stand and added one of these where the flimsy bolt and clamp used to be
I’m hoping this sorts out the problem ....end of edit.
had If you have light weight speakers these stands are great, my Yamaha dsr 15 are 60 lbs, the stands with a little vertical push do lift these cabs up high, the problem is that it takes 2 people to get these cabs up to the minimum height of the stand which sort of defeats their usefulness. I have wind up stands from which I cut 12 inches off as they too were too high for me, I can’t see me doing the same with these, as they are too dear to blow the warranty on. I’m keeping them, not using them right now, don’t tell the wife :)
