I'm reminded of this as I'm rebuilding an old set of Advent Maestros.
Speaker makers have occasionally used various absorbent materials on their front baffles. The purpose is obvious, but it's not clear if and how much it really helps. Has anyone demonstrated through testing a real advantage? I'm guessing if it was a universally accepted idea, all manufacturers would use it. Is it just a band-aid to fix specific response issues in a design that hasn't quite panned out as planned?
Example: Advent has foam on the Maestros but not on the 6003, which uses the exact same drivers and crossovers. Just different shape box.
