Below is an old and not 100% "to spec" drawing of my room. As many of you know I've spent countless hours graphing my room manually, using an SMS-1, REW, and now a new free FR Plotter I found. For the most part I'm getting a pretty good response across all seats, now that I have 3 subwoofers.
I still have some problems that I think are caused by my huge cavern of a room, that opens into the other end of our basement, which is also about 1100 sq ft.
In the pick below, the entrance to the room on the right side near the bar is about 7ft wide and 9ft tall. It leads into 2 hallways, one to the basement extra bedroom and bathroom, and the other to some storage areas, and stairway upstairs.
I'm considering installing a large wood french door, or if I can find some theater type doors, to close off the room from the rest of the basement.
This would give me more of a square room, and hopefully help with some FR issues. The reason I think this is true, is because if I open some of the close doors in this room, and down the other part of our basement, I'm amazed at how that changes certain frequencies on the graph, creating nulls and peaks.
