Getting ready to install new speakers in door. Already have a very well dampened door but will mount new speakers with an MDF ring. Is there any value to making the MDF mounting a larger area than just a ring? Would it improve the midbass to put the speaker on a panel of MDF (6.5" speaker in a 10"x10" square of MDF mounted to the door) as opposed to a ring? I was wondering if the greater mass of a panel would make any noticeable improvement over just a ring?
