Excellent Mike! Your wood working and craftsmanship skills never cease to amaze me, and you always talk as if you just throw that stuff together in short order.
As most around here know I really don't get too overly involved with the graphing, acoustic treatments and such but I do use bass traps and do know that they really improved the bass in our particular room, I'm glad you too are having the same results ... plus, to me, they just freaking look neat as hell.
Anytime somebody sees our room for the first time they always ask about the huge speakers in the front corners of the room, I get a kick out of that.
I notice you also use white plates for your outlets on the front wall, I did also but after a while they became somewhat distracting so I painted the plates the same color of the front wall (red in our case, front wall only) and found that I really like them blending with the wall. The remainder of the room are still white plates.
Way to go big guy, that really came out first class!
