This is a copy post. I thought thay folks here might find this of interest to try and or discuss. Someone asked how they could increase the mass loading of thier speaker/stands. I posted the following.
You can increase the massloading of your speaker/stand system by a significant precent for almost no cost. You will also make the performance and adjustment of your speaker/stand much easier to do at the same time.
   No this is not a mass multipier scam but it is as close to free extra mass as you will ever come and your system will be the betterr for the change! Find a buddy with a drill who also owns a 1/4 - 20 tap and die set. Drill a single hole in the middle of the back edge of your stand about 1/2 inch in from the edge. Cut a 1/4 - 20  therad in each of these two holes. Now mount one of your threaded spikes int the new hole. Now your speaker stand has only three spikes and the mass load per spike has been greatly increased over the previous distribution of four spikes. Now your stand is sitting upon a fully and unconditionally stable tripod. You only ever need to adjust two spikes for full stand adjustment. The spike at the rear adjusts for and aft tilt while only one of the front spikes needs to be adjusted to set left to right tilt. Now experiment with ceramic or such cone devices (three per speaker bass) and have some fun. Please post to inform others of your findings. Best regards Moray James.

Hi Moray,
     I have a pair of modified System Audios, with spikes, and found a 25lb of shotgun pellets also helps along with the spikes.
