Birch vs mdf...Bigger volume and stock xovers

Discussion in 'General Topics' started by Clark Hathaway, Nov 27, 2018.

  1. I'm purchasing all Volt 6's for my surrounds (ported) and Atmos (sealed) speakers. The surrounds will be hidden in columns, so I'm not concerned about finishing them. I am going to increase the surround enclosure volume to the higher end of the design (.31 cu feet)for better bass extension. I have several questions:

    1) If I use mdf instead of plywood for the box sides, what thickness would you recommend (I'm using 1/2 inch mdf for the back)? Or does using Baltic plywood provide other acoustic benefits?

    2) The Atmos enclosures I plan on lining with at least 1 layer of 5/8" drywall to maintain room soundproofing. Is one layer enough, assuming the entire box is built using 3/4" mdf?

    3) Is it worth it to increase the volume of the Atmos enclosures (will I hear the difference) ?

    4) Finally, if I do increase box volumes to the upper design limits, will I still be able to use the stock crossovers?
