Stillpoints and reference-level speakers

Theaudiotweak, I haven't looked but is there a table of speed propagations through different materials? And what does one seek-faster or slower? Also is it frequency dependent? I had a good deal of engineering training in undergraduate school but mainly in EE and ME.

I have a table that can be used. The alloy I was seeing and hearing in "surround sound" had an additive that was a hardener to increase the wear characteristics. Great if you needed brakes for your race car but this one additive made for some crazy scenes. Less than one percent can make for some large differences so there was a long selection process and much listening to all the many concepts. Tom

I look forward to Agear's inevitable purchase of the Backstage platforms and how they improve upon the Apprentice's high standards that we've established here. Agear don't keep us waiting too long.

Agear,
Your SOTA mechanically grounded listening room demands that the Backstage find a permanent home there.

Lord have mercy. Well, if you really want to push towards the lunatic fringe as I am prone to, the Starsound Stage platforms are the obvious answer. They are an ALL BRASS version of the backstage. Due to inflationary pressure on raw materials such as brass, they will be $$$$. My wife would truly be filled with homicidal rage at that juncture. I can hear her now: "Brass stands? Really?"

Well, I am glad for Robert, Tom and the Starsound collective for the resurrection of their company and technology. The Apprentice stands are a very modest investment for the performance you get. The audio press is finally starting to take notice:

The audio press has been very enamored with the Stillpoint products. It will be interesting to see how they find the different engineering approach of Star Sound products. Time will tell.
Charles,

I feel like I need to tell you gentleman here, A long time ago, To me, The most profound resonance control went out of bussiness from the lack of keeping up with demand of sales, so bruce badlack of polycrystal closed down!, I lucked up, found some footers for speakers, I owned thousands of dollars of this stuff back in the day of the late 90s, I will never use my still points again, as of the good ole days, Polycrystal is the shxxx!, Rare to find any, as a matter of fact, Bruce used my invention, the disablocks, for top tunning of componets, they sold quite well, so if anybody has polycrystal products, I will give you double than what you paid new for them!
