Well Outlaws I just moved from the relm of renter to home owner and need some advice. Me and my Wife just went together with her parents and bought a dual 3 bedroom duplex. I'm planing on expanding my living room buy about 5 feet(its just to small right now)by moving a wall and making a bedroom smaller. I'll be using that for a computer room/office. When I put up the new wall I was thinking of using 3/4" MDF instead of sheetrock to stop the Bass from traveling to my inlaws side of the duplex. I also plan to put a door(sealed exterior type)between the living room and the hall that leads to the bedrooms and other half of the duplex. Will this be enough to stop the BASS from shaking my inlaws out of bed? What will the MDF do to the room acustics? Any ideas?

Thanks in Advance
