Isolation pads for the speaker stands

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..

Now remove all the sand and replace with reactive agents such as brass powder or steel bearings. Vibration will be attracted and drawn to these materials.Fill 25 to 30%.. The speaker needs to be terminated to the stand and the stand needs to be terminated/coupled to the floor to make this one continuous pass thru of resonant energy. Soft materials de-couple and store and slow energy, you want to provide as fast an exit strategy as possible. Material choice and its geometry are crucial to this outcome. Tom
