What do you guys think would be a better idea if cost and weight are not an issue, tons of cross bracing or really thick sandwiched MDF and ply. I was thinking of doing something With maybe doubled up 1" MDF with 3/4" Birch on the outside. The only thing on the inside would be egg crate and Polyfill. Maybe even some sort of array of ridges on the walls to break up as many free standing waves as possible without having to fill the inside with cross-bracing.
