Hi Leog,
Love the look of those Tyler speakers and that awsome leather single chair shaped like an 'S' - must be comfortable. I recognize the Rythmic subs as I also have a pair of F15s.
I like to large size and openness of the room. Do you feel that it's too acoustically alive? Do you partially close the window blinds to prevent mid/high freq bounce back from the glass windows? What about flutter echoes between the bare floor and ceiling? Any treatments for the back wall behind the couches?
Looks like a great room to party, entertain or just unwind and relax.
