Guess I should have stopped back in the thread, can't believe the over reaction.
That's OSB (Advantech flooring). Ooooooh, flexy.Also this thread isn't to start a pissing contest aboutf lumber, but to show off my Zed amp build in the Zed sub-forum.Nor was my response. Never said flexy was bad in your application. Love the amps, would never use the material. Has no reflection on acoustic output at one frequency though. I personally don't care about that.
Testing yes, not in a box just as a material. Application doesn't determine usefulness, but the material properties can define what will work in what application. Testing in a specified application will only color the results as it is very hard to make a reproduceable test.
Talking to someone gets you dumb advice like you might hear at SMD. Actually trying to understand something on your own works much better. This is something I deal with everyday: Boeing, GM, Ford, Mercedes, Apple, Google, Samsung....all pay my company and buy equipment from us to do material testing. Structural integrity and modal response is something I have a keen knowledge on.
