Hi Osse, I suggest more bracing it is the resonance that make it move. I guess you are using the cabinets standing upwards?

I braced them according to plan, even a little bit more.

I'm using them standing up yes! It's sad if I have to bring 20-30 kg weights to the gigs I can't use extenders.

I had the same problem with TH18 prototype standing up. First I did some more bracing and then I put some 'stone carriers' (rubber plates from recycled rubber) that helped a lot. i think you can find them at your local BAUHAUS Bäckebol. We use this a lot on our gigs.

looks like this:

How big are those matrasses, do they cover the whole bottom or one in each corner? Thanks for the tips!

originally they are around 40x50cm slap (give or take) and then you can cut, or rather bend them to smaller pieces, it has crosscuts, 2/3 way through. form ons piece you can have 4x6 pieces of 12x20cm pp.

They look like recycled tyre(tire) rubber chips glued together to me??? In which case they would be fairly dense.... dense enough to add enough weight to weigh the cabinets down... hmmm....

yeah they are used to carry stone tiles so they can carry quite the loads. its really useful for rigs for putting under and between stacks of subs or tops. Add in the dampening factor on non slippery surface its a win win.

I was just out and bought a package of the stone rubber feet, but they are small, 60x90 mm. Still much bigger surface than my current feet offcourse!

Hope it will solve the walking subs!

Have you tried raising the back of the sub with a strip of wood say about 1/2" high? Let the front edge of the sub rest on the ground. This should decouple the bottom panel from the ground and remove its vibrations as a cause of the "movement".

PPSL mounting makes for subs that do not walk.
