Importance of wall behind listener?


In my audio setup, I essentially have no back walls to speak of. Behind the listener is an opening into a long hallway, an opening to a den (to the left of listening position), and an opening to the kitchen (to the right of listening position). I'm wondering if this is a hinderence in getting a truly 3D holographic soundstage representation. Other folks who have a near identical systems get phenominal soundstages, so I know it's not any of the equipment. The difference is they have a back wall vs. my no back wall, and their straight ceiling vs. my sloped celiling (peaked at center, dropping on both sides).

Any thoughts?

I have experienced exactly the same results you describe and have therefore always backed my listening chair as close as possible to the rear wall.

I always assumed that the "lean" sound you described might have been inherent to my favorite Magneplanars, but I notice you are not using planar speakers.

For me, in any case, close to the rear wall is a rule of thumb for basic placement, and I only move the position forward into the room to counteract any boominess.

(Nice system and room, by the way.)

If this is not possible for you, I hope you are still able to achieve happy results.

I cannot comment more specifically on rear wall treatments, but I have had everything from fireplaces to big windows and never thought that was a critical element.

I would think first reflections, closer to the speakers and especially on side walls should be more carefully controlled.

I would also think a lively rear wall might yield acceptable results for ambience and later reflections.

But I am not an expert so hopefully we will hear from others.
