I run the LRS and recently found a tweak for the stands you may want to try as they seem identical.
Instead of the flip down risers I placed wood blocks under the stands.
Then on top of the stands I laid heavy weight.
In my case I laid 3”x1” steel plate across the span from one leg to the other.
Dumbell weight(s) on each leg would work fine too.
This significantly reduced the “spring” in the stands and made the panel much more rigid.
I went a small step futher and adjusted the wood riser blocks to bring the panels 100% vertical.
Yes the are aftermarket stands that do all this but this is free and very simple to try.
The result, as hoped, was bass improved a touch in definition but the surprise was imaging. Especially in the tweeter.
I guess the springiness in the stands was allowing the panels to move ever so slightly on bass hits and affecting the imaging focus.
Give it shot. Hopefully you get the same results!
If it does then the neat n tidy aftermarket stands may be worth the investment to keep the nice clean setup you have.
