I posted this question on my own thread
but I think it's a more general question about how to best employ a SEOS in a room. I've tried searching this thread, and other forums, but it's hard to find a clear answer so I wonder if someone can confirm whether my thinking is accurate.
My current thinking is to build a SEOS10 over an 8" in a low profile on wall enclosure. A polar response of the SEOS10 was posted back in post #1393
As I understand it, this shows that +/- 22.5 degrees is approximately the range in which it is pretty much consistently at "full power" (i.e. minimal variation). As you get further off axis then there is some rolloff such that by +/- 45 degrees then you're 6dB down at the top end.
Applying this to an actual room then we can see the disperson of my L speaker below. The area I want to cover with sound is in blue, this requires output (from a flat on wall speaker) over 0-30 degrees. The area that produces 1st reflections off the ipsilateral wall is in red, this requires output from ~-25 to -50 degrees.
Therefore if I mount the speaker flat on wall then two things will happen
1) the 1st reflections from the L wall at the left most listening position will be strong
2) the direct sound at the right most listening position will be >3dB down
This makes me think the correct thing to do will be to angle the baffle by ~10 degrees (to point towards the opposing wall) which will mean
1) the listening position is in the -10 to +20 degree range == sweetspot!
2) the 1st reflections off the L wall will be in the -35 to -60 degree range (i.e. in the region of ~8-12dB down)
If this correct? Is there anything else I should consider with this positioning that I'm missing?
