Sand or shot for speaker stands?

Albert, that is most helpful and sure makes sense. I didn't think of the probability of the stand plus the speaker being top heavy, yet something was bugging me and now I know what it is. I will have to wait a few days in order to find a local store that sells shot, and I am looking forward to trying some version of your process. Thanks.

Hi Redkiwi, I set up the stands with the spikes underneath, and heard an immediate improvement. There is a little more air, less of a bloated bass, and slightly better imaging. The difference is definite, but not dramatic. It isn't awesome yet, but getting much closer.

Hi Guys, Thanks for all your help and suggestions. I will definitely try the #9 shot (thanks Garfish), and the silica sand, with a mask and a big pan (thanks Albert). Unfortunately, shot seems to be hard to locate in NYC, so I have temporarily put "playground" sand in my B&W stands. Anybody know where I can get lead shot in my area? I am just breaking in my new B&W 805's and if you will forgive the pun, they seem to sound a little "drier" now that the stands have been filled.(Redkiwi)Thanks for making me aware of the possible liabilities. The sound does seem a little bit more closed in, but it is early in the a.m. and volume is low and the speakers need to be placed more precicely, so I will check into it later in the day. My room is 20 X 12, and my floors are wood, which "gives" a little, with an 8 X 10 rug and the usual assortment of furnishings. Do you think I should use the spikes instead of the rubber stickies on the bottom of my stands to counteract an uneven and slightly "floppy" floor?

Redkiwi, I want to be clear that I am asking about spikes into the floor instead of rubber feet. The 805's have an option of suspending the speaker itself on a type of small spike or mounting it to the stand with 2 screws through the plate that the speaker sits on directly into the underside of the speaker itself, locking it into place. The stand is a bit wobbly, even with the sand, so I guess I will try the floor spikes. I think that B & W's stands are aluminum, with a steel base. It seems that the speaker have good transparency, but are not imaging that well yet. I don't know if it is speaker placement or the sand fill. I will try the spikes on Sun. afternoon and see if that helps. I am still breaking them in and these sound aspects may change. That was very interesting info regarding resonances, and it makes sense to me.

Albert, When you mix the shot and the sand, do you put the shot in first and then the sand, or do you alternate with a little of each?
