Thanks for sharing.
I find room acoustics very interesting and undoubtedly the least focused on aspect of hi fi but the one with the most profound influence.
Concert Halls don't happen by accident and neither should your room.
'Tuning a room' is, I suggest, saying that you are controlling standing waves and their surface resonances in a musically appealing manner - which is exactly what traditional room tx's aim to do but in a much cruder way: I liken the traditional front wall/first reflection absorption + bass traps + rear wall diffusion to weeding with a shovel - you may get the weeds out but you generally so alot of damage on the way.
You give texture to you music by what you listen to it in.
Anyone who thinks otherwise hasn't heard a well 'tuned' space.
Bravo mate - please share your progress.
