space a series of absorbers along the length of the wall. so you'd have an absorber in position #1, then further down the wall towards the back, you would have another, and another etc. you have parallel surfaces. those surfaces will generate reflections between them - you'll hear them as slap echoes and phase shifts. so attenuation of those is important as well as general attenuation of indirect sound energy in order to achieve the frequency and time responses you want.

nice, thanks for replying!
So, i am thinking of doing something like this following your above details for the size of the panels. Posting a rough skethup with not exact room dimensions, yellow means absorption and those on the ground are meant to be on ceiling. I also was thinking of something like a sliding panel for the window.
a sliding panel or shutters. a novel approach might be a 20mm polycarbonate sheet on sliders, or hung, with the absorbers attached so you could still get some natural light between the absorbers, plus, if not done already, add some additional isolation over the windows.
