Speaker stand spikes ~2” long?

The two primary variables for audio cones are material, size and shape. Oops, that’s three variables! The cones should be extremely hard, not like brass or aluminum or carbon fiber which are pretty low on the totem pole 🗿but like tempered steel and NASA grade ceramics. The cones should be ballistic shaped with the very best shape looking like the tip of an ICBM 🚀 Hey, I just described the Super DH (Diamond Hardness) Cone! The Jumbo DH Cone is the same ceramic materiel and the same size but not quite as ballistic in shape as the Super. And it’s performance is not quite as high as the Super but almost.

The super hard materials are to bright..they tend to make the soundstage crawl up the wall in front of the listener. All materials vibrate and the harder materials have a higher velocity and make the air vibrate faster which makes for more listening fatigue. A simple cone geometry allows for reflected energy to re enter into the system.Tom

Funny guy, obviously you’ve never experienced super hard materials. What do you expect from someone who doesn’t think isolation is real?  It’s real and it’s spectacular! 

Tom, I have sets of Sistrum platforms and while I will say they had a positive effect under Zu Definition !V speakers, the ability to move the speakers became problematic. The platforms’ Audio Points were difficult to adjust for stability underneath the grates. So, looking for something more simple. Have numerous Audio Points with the platforms but the thread size precludes the use. Any ideas?
Have hardwood floors over concrete.

Thanks for all of the recommendations but I found out that Dyanaudio has a 2” XL spike that I can buy separately. 
Hopefully these work but I still would love to check out the Gaia II feet but have a hard time justifying the $800 price tag which is half the cost of my speakers. 
With the isoacoustics Gaia II’s I’d need the ones that hold around 100lbs as my speaker stands weigh 50-55lbs and my speakers weigh 40lbs.
