Another happy SM80/BT-12/K&M crank distance rods here. I had the same problem when I first got the SM80s. They would spin around sending sound either away from the front of the stage or towards the stage, sometimes creating feedback. I used gaff tape to hold them in position, then ratchet straps. My life has been much easier since the BT-12s arrived. I use them even if I don't need to tilt the speakers to prevent the spinning. They are also amazingly built tilters. They weren't cheap once I paid for shipping, duty, taxes and converted to Cdn$, but totally worth it.

Take out what ever plastic cap fills the end of the stand tube so that the speaker socket rests on the aluminum tube end. See Gordian Knot.

I use a method I have been doing for years - cost?... zero.

I take old plastic containers - like those that contain vinegar, oil, sauce etc and when  it is empty, I cut small pieces out of them about 3" by 1" and round off the edges to make small shims.  I get dozens from one container.
Because the container is already curved, the shape of the shims is perfect.  I take them to shows in a  baggie and once the speakers are positioned, I slot them up into the top hat positioning them at the back so they cannot be seen - usually 2 is enough. Takes a second and costs nothing. If I don't end up getting them back - oh well I gots me plenty more.......
That is a great idea Debbie, I am going to try this on my 815's...

After 2 gigs, I am super happy with these Danley SM80s.  I am getting even, articulate sound at a reasonable volume, using relatively little power.

However, with occasional wind gusts, I am experiencing a "sail" effect, which rotates the speaker in the K&M crank stand.  I used a temp fix with gaff tape, but I'd like to see if anyone is using a more elegant solution.  Some thoughts include a grooved plastic piece on the top of the pole, or something more drastic to keep it from rotating.

Thanks!

I just crack a few Solo cups up and slide 1 or 2 pieces up in the back between pole and top. Easy to size as needed. They seem to be everywhere........   ;-)
