I'll try to do that, hesson.
Concerning back resonance, there is a thought gaining ground that backs that freely vibrate results in the guitar's sound being more resonant up close, but in the big picture a freely vibrating back actually -robs- the energy of the soundwave's projection. Big splash with little travel. It would be an easy experiment to conduct if a pair of people could get a decent classical guitar into a large room and take turns listening and playing, alternating with the back against the chest and with it off.
There are well respected luthiers that laminate their backs and sides to intentionally make them more rigid, thinking that will force more of the string's energy to the top.
