I'm intending on using 3/4" thick cork on a cabinet exterior.

well if proof enough, why not ?! I will iuse it above a thin layer of another hard structutal material : lead, aluminium, thin osb for instance... but I have no measures on hands to claim that... just a presumption : often this damned mass - spring - mass damping law !

I definitely want to get into more interesting materials and methods. First I need to lay down a foundation of well known methods first.

Having changed jobs at a most inopportune time ended with me in the unemployment line in April. So I had planned on starting a gofundme, but thought I'd supply one round of data first so people can decide if it is worth while or not.

It's going over a 3/4" plywood structure. The edges will have hardwood protection and I'm hoping to dye the cork somewhat to rid it of the "poster board" look


I'll have the wife "pinning" project lists on 'em otherwise.

Hey, corck should be verry cool material to smooth the edges with a slow shape in order to tame difraction and have a better soundstage ! Btw, look at a corck for wine bottle : a bafle should lookhalf the same for a better soundstage ! Not easy though, tear drop mold seems easier but that's another story

Set it up. Stuff ain't cheap, unfortunately.

yeah but ... not very wear resistant. The hardwood will help protect the edges better so all the shaping will have to be done in the wood.

I'm just looking to further damp the panel(s) and a new material to work with/try out.

Augerpro, really think you should stay on few common choiceS easy to find for convenience if you have a commercial project as Troels Gravsen for instance.
RenShape is a more modern material adivised by Gedles has it all : internal damping and structural and easy enough to work, though not common and perhaps not as cheap !
For diy a clean thin ply without veenering for external and a main chip board layer la BBC is certainly easy to do, the glue in between (or why not double adhesive tape for convenience and rapid work) is feasible by most of unskilled people as I am and can e ordered from a local carpenter. Though your country is big enough maybe for flat packs you can manage la DIYsoundgroup. Not feasible in CE as pointed T. Gravsen already.


Ply is a no brainer imho ! Can be thin, the greater number of layers the better.


my two cents, YMMV. looking forward to see your results once you measure

I talked to the Renshape people a year or two ago. The shipping to Denver was ABSURD. It would only work if you had a local source, they didn't give me one and shipping to individuals was not in their interest at all.

There is a a masive thread already at Diyaudio, believe the spirit of this thread is just about testing the most common solutions if I understood.
I agree its best to keep cost and time investment down. Thats why I recommended sticking to the the things I mentioned and not exotic rock boards, and specialty foams.
