bass affected by stand filler level?


Does the level of sand in speaker stands have a noticeable effect on bass performance? I have a pair of Dynaudio Focus 140's on Dyn's Stand 4 stands. I have had them since February. They are fully broken in. I have both tubes filled full with sand. Will the bass be fuller if less sand is used. I use a Musical Fidelity a3.2 integrated and a3.2 cd player. I also have a Rel Strata III sub. Please limit your answers to the specific question; refraining from suggestions regarding amp changes. With two kids in college my upgrade wish list at this time is just that- wishes. Thanks for your input.

Fill them suckers to the top! :)

The true answer is that there is not such thing as "over-damping" a speaker stand... the mass is needed to transfer to floor or subfloor that can reproduce beyond the actual range of the speaker.

High mass and NO decoupling is the best for speakers. Don't believe the marketing crap... firm coupling is the only rule with loudspeaker enclosures.
Not a good "opposite proportion" at all. The less filler, the more open area you have to resonate and the thin walls do not have attached mass and turn the area into a resonator. REMEMBER: thin & light material + rigid + vibration = a classic transducer. Just research NXT for more info on this. You cannot "tune" a speaker stand. It either creates undesired resonance due to lack of mass... or it is silent. The only way it could sonically "help" to have a hollow or partially hollow tube underneath a BIG vibrating mass (called a speaker) if is you actually ENJOY distortion and a steel tube trying to reproduce frequencies... but there is no in-between. I personally do not want a steel tube or other non-damped material to attempt to "reproduce" frequencies other than my loudspeaker :) You will get lower bass response by moving the vibrations to the floor, where the sheer size is able to help reproduce low end extension. Worst case is the floor won't resonate and you will just get the actual loudspeaker reproduction response... both a win-win.
That is a really good point Tbg... If the environment has vibrations from outside sources, it could transfer more to the loudspeaker. This just keeps pointing to an alternating material decouple as the best scenario with environment in effect. Solid mass to prevent too little mass and turning to a transducer and decoupling to remove cross-induced vibration. Shadorne is also right; in that the better the enclosure, the more ability it has to contain the resonance it cannot control from passing into the stand to begin with.
