We are buying the house we leased last January. It has a 3 car garage and the P.O. walled off one bay for an office. It is storage now but I'm going to empty it and take it down to bare walls. I'll wall up the garage door opening and add a high window. That will be the speaker end. I'm thinking about building a floor to window QRD diffuser behind the speakers. I'll do bass traps and absorbers . I'm open to suggestions.
