If you front mount the speaker, you'll need a seperate grill frame (or another baffle) to hold the grille cloth. Depending on how you design the grille, that can add a lot of weight to the cab...but can make speaker changing a little quicker if that's a consideration.
Agree. You want as solid a baffle as possible. You want the speaker to create the wave form. If the baffle is moving it will create another wave as well, which will distort the speaker's output at best and cancel out the speaker's wave at worst. With the intense movement of the diaphram in todays speakers, the speaker needs a firm seating.
