Extending existing ceiling joists?

I have the fortune to be able to build a homestudio from scratch.
I want to build a solution that Ethan from Real Traps talked about in Doug's homestudio video posted on his site.

That is to fill insulation between ceiling joists, and then cover it with fabric.
My ceiling joists are 15cm long, but I would like to fill it with 30 cm (12 inch) insulation to get the result I want.

I'm thinking that I could extend the joists 15 cm so that I can mount the fiberglas in it.

How would one go about the right way to do this?
Is there a easy, right way to do this?

KK

I'm not a construction expert, but I wouldn't extend the joists to be lower with heavy wood. Maybe you can make a structure from metal studs or some other light and inexpensive material?

Thanks Ethan,
Yeah I was thinking of mounting something "L" shaped down from the joists, (15cm long) facing each other on each studs, so that it will keep the mineral wool in place.
(Maybe 30 of them all together across the ceilling)
And then maybe attach metal studs where I can attach the fabric.

But you don't think all that metal will resonate?
Maybe I can find some "L" shaped in wood....?

Thanks,
KK

How about a drop ceiling grid? You can then place panels in each grid and fill above it with fiberglass.

Glenn, would that yield the same effect as with fabric and 12inch mineralwool?
And would you have any space between the panels and mineral wool, or just keep it compact?

I really want to"kill" that ceiling so that it feels like it's not there if you know what I mean

The drop ceiling would have acoustic panels and above it I would stuff with fiberglass. You can give yourself a 12" gap from the ceiling now.

doubt you need to double up on each side of the joist.

ive seen people make a suspended grid with cheap corner bead. no need to spend a lot of $ whatever would help your ceiling fabric treatment look best is what i would do.
