Im feeling like the bottom might be the achilles heel of the design.

You did so well with the bracing and deadening of all other sides, then the bottom is a thin flat sheet of plastic (as far as I can tell). Seems like that would need some extra deadening to keep it from acting like a PR at it's resonant frequencies. Maybe pinewood derby car weight plates or shaped steel plates attached with 3m double sided tape. Something like that would add a lot of damped mass... hopefully without awkwardly sticking out the bottom.
