I found an ancient thread about duplicating the borosilicate paint that Totem uses on the inside of the cabinets.
I can't post a link for it but it was way back in 2002. Very fascinating stuff.
Anyways, I'm building a sealed enclosure for my Alpair 11 MS and thought I would try it out. I had some thermoelastic paint in the garage so here is what I did. I took two chunks of Tektite (glass formations made from ancient meteorite strikes) and pulverized them with a hammer. Poured the dust, flakes and chunks into the paint and stirred. Painted onto the inside of the cabinets. It looks like I poured an oreo shake into the cabinets. 😋
Any theories on whether I should still stuff the box, or should I try them sans stuffing first?

Here it is
My question might be stupid or funny but anyway 🙂 As you may know, I am building a clone of the Arro and I noticed that Totem uses a borosilicate paint to damp the inside of the box. I did not find this stuff but I am wondering if a can use a similar product (like paint) or if I can create a similar product. And here is my funny question, what do you think about mixing normal white paint (oil based) and sand or other similar stuff in order to paint the inside box with that "black magic" paint. Sand with glue? Plastic finish paint with glass?
If I am crazy
, please suggest me...

I care because I don't like to see people wasting time...
IMHO it is at least expensive. Tektites have the same chemical composition as their precursor rocks (granites, basalts, any SiO2-containing rock), which is nothing special. But tektites are quite rare (e.g. the moldavites found in Czechia). Mineral collectors pay a lot of money per gram for tektites, even for those black ones from the Philippines.
Could it have an effect in damping? Maybe, but it would be cheaper to enjoy a good Merlot, crush the bottle and use this glass as a filler for paint.. Brown or green bottles will not differ substantially in their chemical composition from tektites but eventually the Merlot contributes to some damping, too🍾
The above ideas sound rather exotic.
If it was me, I would tend to choose more 'down to earth' materials like a combination of perlite and expanded polystyrene bead added to a water based elastomeric coating or even latex paint to achieve a similar, if not better result.
But then going to a job site and scrounging some PVC tile or flooring cut offs might be even better. Heck, why not do them both?

I think the main benefit would be due to the binder, not the filler. Some kind of elastomeric material might work better. EPDM or sno-coat, both used for waterproofing roofs, come to mind.
It looks a bit like the MDF bracket that I wanted to look like cast iron, so I sprinkled sand onto the wet paint, then painted over it. I think a test piece would be a good idea, how does it sound when you knock the cabinets?
I've glued felt to the inside, then glued carpet tile to that, and it seems to work well.
I'd stuff them with cotton wool.

Pretty sure you still need to either line the box or stuff it, to prevent reflections from the passing back thru the driver.
I wouldn't bother mixing up some mysterious goop for the interior, but that's just me.

I used a roof coating (Sta-Kool I think) that I used for the top of a shipping container (to keep it cooler in the summer). I put it in pretty thick, so even if the Tektite adds nothing but mass, the paint should dampen a little bit.
Oh c'mon Jeff, you know I'm itching to give other suggestions. No shutting me down like than, man.
Hmmm...
.45mil sheet can be hung from the top of the cabinet, a couple cm from the walls. Add some holey lead sheet here and there, a few PVC tiles, a little elastomeric with the EPSB and perlite on the walls then some rock wool to the cavity and you're done.
Or you can just deal with a little bracing here and there and do what the pros do and add a little cavity stuffing.
Your choice. Do what I have suggested above and come back with tested results. You might just find why the big boys don't dabble too far into the realm you bring forth.
Anyway you slice it, it's fun.

I use organic stone ground silica with grade 5 Alaska gold granite.
Only optic grade quartz is used to grind the silica exported from spruce pine mine.
It is ground for 30 years in a solar powered humidity and temperature controlled environment. With free floating galvanic isolated bearings
with tectonic high purity rubber. This dampening isolates any misalignment of the silica sub structure which keeps away further impurities.
The already ultra pure optic grade sand is mixed with a 10 step heat treated selenite from fake moon rock recovered near the Alaska 5 high purity grind stone
Due to a slight solar flare last year the recovered sample was determined to be 99 percent pure.
So only vintage grade MDF that has been preserved before above ground testing can be used.
Later research showed dumping cat litter into, recycled low carbon latex paint achieves similar results.
Holographic sound stage with wide forward presence is achieved.
The latex paint was only produced by sears from 1933 to 1938 and is very difficult to source.
