I tried to describe this room last week in words and nobody really understood what I was talking about. So, now I have a link to a CAD drawing: http://www.math.msu.edu/~borosnic/roomdesign.pdf

The 14' by 15' room with the extended bay cutout is the room in question. The room would have an 8' ceiling. My dad is planning on building this room for a theater room. Due to his other plans for the basement he is hoping that this design will work. However, if I can convince him that the acoustics would be terrible then he may be able to choose a different sized room that would be better.

Is this room going to cause big problems for acoustics? What would the problems be?

thanks in advance for any replies, Nick
