I was reading the HT2L review by audioholics and noticed that there is a secton where the reviewer described that the HT2L actually has fewer internal braces then the Song towers, and according to salk he explained, that the 1'' MDF thickness of the wall actually increases rigidity, allowing them to use fewer internal braces. My question is, if one choses to use 3/4'' MDF, how is the rigidity of the cabinet be compensated? Thank you
