That part of the room is about 3.60m wide, 4.60m long and 2.60m high, so the dimensions are not too far off from yours. Maybe you'll find some of this useful/inspirational: I ended up building two big panels. each 3.00m x 1.20m. Each big panel is made from 5 smaller Troldtekt (http://www.troldtekt.com/) 1.2x0.6m acoustic panels. I went for the "Troldtekt Plus 75mm" variety, which consists of a 35mm thick layer of "wood wool" backed by a 40mm layer of mineral wool. The big panels are suspended ~0.25m from the (concrete) ceiling, by screw-in hooks and metal wires. Leaving some room behind the panels (as opposed to mounting them flush against the ceiling) improves absorption towards lower frequencies, and I still have ample height (~2.30m) below the panels. Also: suspending with wires means that I have the option of (re)moving the panels, leaving only 2 x 4 small holes to be spackled+painted.
