I have a nice horn tweeter, a JBL 2012, and an active crossover at 1600Hz.

Can I just mount the 2012 onto a hole in a board and listen to it? How big does the board have to be to count as a "baffle?"

Is the point of the baffle (or, what is the point of the baffle?) to separate the rear waves from the front? And, how does this differ from an infinite baffle sonically, i.e. if a little is good why not a lot - mount the speaker in the wall?

Maybe if the sound is "thin," it is the bass you are missing. (?)
