With the premise that I'm not gonna change the layout of my room for a long time as I lack the physical energy to move everything yet again (plus, I just ordered a 120'' screen for my projector, and I'm gonna hang it on the wall) I found this listening position absolutely phenomenal:
I simply went behind the desk to change a cable and I was blown away by how tight was the bass (plus, you know, I was actually hearing it).
My previous listening position was similar: both speakers were facing a wall, and apparently I had inadvertently found one of the best listening positions. Now, well, I'm sitting in probably the worst.
At some point I think I'll have to give up my home theater and revert to the original position of the speakers, or start to set up treatment hoping to get a result I naturally have just by having the speakers closely face a wall.
By the way, it looks like I'm sitting in the center of the room, from the pictures, but it isn't the exact center. The speakers were previously slightly closer to the wall, but that position resulted in even more cancellation, so I brought them a little closer. What I hear from my position is still miles worse that what I was hearing in my very first setup, and from what I heard a few minutes ago simply going at the opposite side of the table.
Regarding the sub, well the response is fun for movies but loud and confusing for music, its reminds me of my first 1st gen Rokit 5, a pair of headache inducing monitors with an exaggerated bass response. This sub is their direct cousin, albeit I'm sure my room is playing a part as well.
