Given all the speakers I'm currently building, I need adjustable speaker stands so I can quickly put them at the proper height for auditioning. Any ideas regarding material, design, construction methods? Structure damping? Isolate the stands from the speaker only, or speaker and floor? (I currently use sorbothane buttons between my stands and speaker, and ordinary rubber feet between stands and floor). Let's hear your ideas!

That's kind of what I was considering too. My speaker measurement stand is built that way. I used 3/4" plywood and MDF in its construction. There is a lower "sleeve" mounted to the base, and an upper sleeve that supports the speaker. The sleeves slide within each other and I have drilled holes every 1" through them and use a bolt through the holes to set the height. I was considering the aluminum extrusion with T-slots but I may just do something similar to my measurement stand. Possibly use sand in some sections for damping and rubber to isolate the stand from the floor and from the speaker. The aesthetic part needs consideration too.
Requirements?
Max. Load/weight?
Height?
Length of adjustable range?
Finish/looks?
Adjustment method?
Manual with lever/ some sort of quick lock.
Automated with pneumatic/hydraulic actuators? (Like height adjustable desks etc.).
There are a few companies around you can gander some ideas from.

I made my speaker stands from aluminium profiles:

Meanwhile I have modified them to tilt the speaker a bit backwards.
I used something similar to these: https://www.item24.com/en-de/profile-technology
They have everything to make them adjustable. The profiles can be filled with sand.

I've made several things with that type of strut material with good results. There's a brand in the US called 80/20 that's pretty available. The finishes are nice and it's easy to work with. Lots of different profiles and connectors. You can cut it with a woodworking chop saw or table saw. Odd angles are somewhat difficult, though.
Regarding height, something that can I can put a 1970s style monkey coffin on at its lowest setting, and a small desktop size speaker at its tallest setting. Ear height is assumed to be around 38-42". Weight limit, maybe 50 lbs? How much does a monkey weigh at most?
Probably manual action, I don't want to spend a lot of money on actuators. I don't have opinion on looks yet, I was hoping to get some ideas here.
Why can't you build them at the correct height to start with?
Why can't you use a combination of phone books and cinder blocks like everyone else?
Builders screw jacks?
Would need to be secured to a decent base and a plinth added on top. Most would be too tall and need cutting down first but that was my first thought.
EDIT
Called ACCRO props here in Oz

Another thought along the same lines
Caravan/ car support jacks; same idea but they use pegs in though holes as the height adjustment so not as fine.

Just a thought. When I measure, I use my 24" stands placed on an 11" box.
At one point, I was thinking about making a 4" box that is open on the bottom, to hide temporary x-overs. Most likely MDF with 1/2" round-overs. I don't need the extra height, but it wouldn't hurt anything.
