Isolation pads for the speaker stands

THORMAN
Thanks for help. I also have Skylan stands and Carbon 7
speakers with the thick walls. I will try today to remove
sand from the columns.

I would try removing the pads, giving a hard coupling between the speaker and the stand. Small spikes, wood buttons, etc. Anything that isn't squishy may firm up the sound.

O.K. I removed the sand, left approximately 1/3 and the sound
improved (no heavy bass). I will also replace dots with
softer bumpers.
GUY'S, YOU ARE GREAT. MANY THANKS TO ALL OF YOU AND
MERRY CHRISTMAS

The bass never changed..the spectral balance and dynamics changed. The sand and soft materials suck the life right out of thin air resulting in a dark and deaden sound..No air, what you have left is the perception of more bass and less of the musical event. Tom

Kiza : Glad things worked out..Funny how things can change with more or less sand.....The transition between Stand and Speakers is also a crapshoot..Herbies' stuff is great..Many like Bluetak.......Just keep trying different things an eventually you will find the right cure..Every situation is a little different..
