Speaker Stands Filled With Kitty Litter? TRUE???

yes, I have my Lovan Jazz speaker stands filled w/ kitty litter (which, as Albert correctly pointed out, is ground clay). the speaker stands are (acoustically) dead to the knuckle rap test. I have my Tannoy DMT-10 monitors sitting on these stands & I find their sound is very good. This is in a bedroom system which is not very discriminating, I have to admit (hence the diff in silica & clay might not show up). clay is a real option for mass-loading speaker stands. I found it to be a better option as the play sand was leaking (over a period of time) from the several places in the stands & creating a mess on the carpet! I found that the ground clay's bigger particles stayed in their intended location better while (still) providing mass-loading. Anyway, FWIW:

Bombaywalla: Thank you for your reponse and your honesty. I appreciate your frank opinions within this thread. I've heard others using it and glad to hear someone coming forward with admitting its use. Kudos!!!

I am a sand/lead shot fill type of guy myself. However, it you decide to use clay, you might want to visit your local automotive store (AutoZone et al) and check out “Dri-Zit” or “HiDri” floor absorbent products. I have found that Kitty litter and others contain a litany of non-clay materials. The floor absorbents are Georgia’s Fuller’s Earth, which I believe is clay. Oh yeah, what ever you have left over after filling the speaker stands will come in handy to clean up those nasty oil spots after an oil change.

Try lead balls or marbles, but if you don't have the balls, or lost your marbles like i have, kitty litter should work fine!
