Open Baffle Speakers: Question About Materials

I am wondering whether the materials and construction methods used for the frame/baffle of these designs matters. In other words, is it necessary to build the frame/baffle so that it does not vibrate/flex/move in response to driver excursion/vibration? If so, what are some of the popular open baffle designers (Spatial Audio, Pure Audio Project, ETC) doing to mitigate this issue?

When @ricevs (Ric Schultz) was making open baffle/dipole speakers and subs (employing the Rythmik Audio/GR Research Sub DIY kit) he made his baffles by gluing together three layers of 3/4" MDF, using Green Glue iirc.

One great method for creating very non-resonant baffles is to put a layer of ASC Wall Damp material between two layers of MDF or Baltic Birch Plywood.
