Wow...they really screwed up that room!
That is a 95% reflective surface, it's better than what he had, but still not a properly treated room.
First glaring mistake is that the system is setup off center. It is closer to the left wall. This will throw off imaging.
Next, the wall surfaces will break up all the waves in a completely non-linear manner and he will have reflected sound broken up many times AND still hitting his ear at different time delays. I expect the room to sound quite muddy (pun intended!).
Seems like aesthetics were the main focal point for complete disregard for sound. First reflection points MUST absorb high frequencies. Corners need to be bass trapped. If the room is somewhat large, best to do diffusion on the back wall, but most rooms are not. Should be thick completely absorptive panels behind the listening position.
He definitely was right about the mid drivers / tweeter to be somewhat ear height. Ears should be somewhat in between the tweeter and mid area to get the proper, time aligned presentation.
That architect should have at least attempted to read up on acoustics before building out a whole room like that. The only concept he vaguely understood is how walls should not be completely reflective, that concept about breaking up the reflection etc.
Anyhow, I'm definitely NOT impressed with what was done. However, I do applaud the thought behind it. His mind was definitely in the right place even though the implementation was not.
What do you guys think?
Also, I didn't proof read my post. Apologies for mistakes in grammar, sentence structure etc. Just wanted to blurt it out
Might fix all that later.
Ask him for some pointers on what he thinks should be done to acoustically better your listening space. 
hyeah:
