WOW, ether you very good with the camera or you’re just a natural with the camera but these images are nicely detailed. One thing with sofa placed to close to the back wall and with just a single loudspeaker for the centre back surround that will limit the uniformity of its use of that channel. I’d place a few on the back wall to give even coverage without the hole in the bucket. If this was tried in the cinema it would fail miserably.
If you where to seat yourself off the centre-line of it and listen very, very carefully you might hear what is missing. If you sat further away from it, you’d hardly notice it.
Still that is one fine looking set-up that you’ve put together and thanks for sharing.
