I have a guitar room that I would like to set up for recording and playing of sometimes loud amps. The room is about 15' deep and 10' wide. This room is in the basement and off of the main rec room. When I play now, will often crank up an amp in the smaller room and stand in the larger room to avoid being blown out. I could record the same way, amps in one room, me in the other if needed. It would be nice to be able to crank up to a reasonable level in the room and either stay in there to play and/or record. Would my best option be to build an isolation closet for recording and playing loud amps? Would a ClearSonic sort of drum enclosure with a lid be a good portable (but more expensive) solution to the volume problem? What sort of wall covering should I use for this room to help control the volume? Any advice would be helpful.
