Jim smith. He is very knowledgeable. Anybody else how do you know if they know how to do this. I’ve read Jim’s book, Paul McGowan book, visited and asked Cardas and also have info from the old Rives Audio room setup, so I do my own setup using the techniques from everything above.
When I moved to Florida, I had to give up my custom built room to move into a new house with a much smaller room, so I had to get smaller speakers which allowed me to get rid of some room treatments.
Try setting up things yourself starting with the rule of 1/3 or 1/5 and jim smiths rule on the separation of speakers compared to distance of speaker to listeners head.
