Placement of diffuser

Hi All, I have a home recording studio.the is a glass partition on both side of the room.so please can someone advice the diffuser placement. Room Size is 12'x13'x10'

There is an announcement at the top of the forum about what to do to assure getting as many responses as possible. The announcement leads to this post (click here). Actually, several people, who are experts on this forum, will most likely not reply if you don't do what is written in that post. Many others who are very helpful, will most likely not reply out of respect for the moderators' wishes. But to answer your question: That diffuser should be located OUTSIDE the room. That room is way too small to be able to use a diffuser in any case. - Stuart -
