How thick should the front baffle of speakers be?


Some manufactures advertise or hype a thick front baffle, two layers of MDF,  if the woofer is as thin as  paper cone how could it change anything. Could be just hype

3 things make a great speaker,the cabinet which of course includes the front baffle (not hype in the least),the drivers and last the crossover.TO see some companies that are leading the way look at Magico,Rockport and YG to name a few leaders in the field.Good luck!!What speaker do you have?
Help me out here people. If the cabinet does not effectively deal with the waves off the back of the drive they will just bounce off the cabinet and the back of the drive. They bounce through that paper thin cone and ruin you precious sound. Hell you pay big bucks for your source and pre and amps and then the speakers reward you with crap. 
@soundsrealaudio a cabinet is the only practical way to eliminate rear waves.

This however creates the problem of cabinet vibrations and rear waves being passed out the thin paper cone.

Only solution is an infinite baffle with no cabinet.
