Room and Placement for Revel Studios

In response to your last paragraph, I don't think there is any advantage, in fact I would suspect the opposite. One thing to consider, given the width of your room, is to try setting up your speakers on the long wall - that should pretty much take your horn shapped 'side wall' out of the issue. Personally I've never cared for the sound of long wall set ups, but a lot of folks really like it.

As you say, try them all, that is really the only way you will know.

You might be better to sit in the wide open part of the room. If you sit at the low ceiling end then you will get reflections from the change in ceiling height and room width (an interfcae that will be all too close to where you sit). It is always better for the sound to go from narrow to wider than to go from wide to narrow. It is always best to sit away from reflections and by placing your speakers out into the room (6 feet from the back wall) then you can largely eliminate reflections from the lower ceiling and width and the interface between the two parts of your room. Since you have 14 feet of space in the wider part of the room then you could place your listening chair 6 to 8 feet into the room roughly 8 to 10 feet from your speakers.

Good point Shadorne, I never thought about the possibility that the OP would sit in that area. I agree with your suggestions if he can't sit within the 14x20 ft area. I would equally recommend that he not put his speakers in the area you thought he might sit.

FWIW.
