I thought you needed an elastomer like layer? Does the cork qualify?

Nice, cork boards and rolls are available in office stores... Can I stick cork on the inside of MDF cabinet? Anything else I can stick to the inside face of the cork?

Maybe constrained layer isn't the proper term.  Cork is used in sound insulation and in the sandwich I put together seems to damp the ringing you get from typical plywood.

You could put cork on the inside but I think having a layer of cork between another layer of wood might be more effective.  I wouldn't take much to try a single layer and see how it works.

I'm doing an MDF-silicone-tile constrained layer on the Shockwaves, at the rate I work, they'll be done in a few years. As soon as my sister and I move out of mom and dad's house, there will be room in the garage for... well, being able to reach the project, haha. I bought some 97c tiles at Lowes and used 3 or 4 tubes of silicone on this carcass, I haven't even glued the second one up yet.

**Bricks not included.

Is the silicone caulk enough to hold the tile in place over time? Are you using any stronger glue? Also, what are you planning to line the tiles with?

Ron_E

I used to use silicone caulk to build crossovers with.  I recently tried to recycle some parts from some speakers that were probably 25 to 30 years old and broke one of the ferrite cores trying to pry it loose. I had to cut the caulk to remove the parts.

ok, then that's good then.... I like how the silicone caulk is a little flexible and hard rubber like rather than completely rigid... except for the smell while it is drying

Well they've been sitting in that spot for several months, surrounded by boxes of junk and the tile hasn't moved, I'll get my micrometer out when I can finally get to them to do some more work and see if the panels are still 29.85mm thick.

They'll be lined with 3/4" sonic barrier.
