I think Sogood's suggestion is the best place to start. You are still going to have some boom. You will either need to build a high Q resonator or possibly correct for the remaining boom electrically with something like our PARC. Even if you do intend on dealing the anticipated problem electrically--try to do everything else you can to minimize that amount of correction first. This is one case where you should build the walls one layer 1/2 inch sheetrock and insulation behind. It will allow the walls to give and reduce the Q a bit.
