I’m looking into treating my listening area and haven’t quite been able to get the left/right soundstaging nailed.
Overall, the issue is the room configuration itself, but unfortunately that can’t be changed. The listening position can’t be changed either due to space constraints. So this is an exercise in just making it as good as it can be.
My listening area is open to my kitchen on the right side. So there is a wall down the whole left side which is fairly close to the left speaker (1.5 ft or so), the wall on the right side is 3.5 ft away from the right speaker and extends from the front wall towards the listening position approx. 4ft and then stops to open to the kitchen.
I’ve been playing around using soundstage test tracks and positioning absorption (just using cushions/pillows etc.) and I can’t get the far left (off-stage left) position correct. It sounds like it’s coming from the right hand side even though the first reflection points on the right have been treated. It’s strange, it sounds like a lot of reverb originating from the right side of the soundstage when the voice should be originating from well outside the left speaker (I know…there’s a wall there!!). The other soundstage positions sound good.
So, I’m hoping maybe someone here has already dealt with this type of situation successfully and can point me in the right direction (without putting up or tearing down a wall or moving!!) or at least help me with the following questions as I continue my investigating/trial & error:
- Which speaker and wall (boundary) interactions come together to create the off-stage left (very far left) image?
- Is there a way to make a wall act like an open space? (ie: mimic my right side open kitchen on the left hand wall)
- Is diffusion the key, rather than all absorption?
Thanks for any thoughts/ideas.
