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

I use 25mm Baltic Birch for every motorboard I build and if the area of the sides is large there too. Really tough, no outgassing or fear from water damage like MDF and no voids if you stay away from the Chinese stuff and use only real Baltic Birch. Reverberation happens more than people think and thicker plywood is a great answer. Build your cabinet right and all the bandaids for poor cabinets like expensive feet are not needed.
