Are those membrane absorbers?

Most definately acoustic foam by illsonic.

I believe that is acoustic foam panels by Sonex. And no, those are not membrane absorbers. Look at the angles they are hung at. These are stepped to reflect sound to the Skylines in the rear. I believe this produces not only some diffusion, but diffraction around the rear edge which adds to the overall absorption. They also have foam above to absorb sound reflected from the ceiling and stop any standing waves between the ceiling and reflectors below. This stepped reflector concept is used in many outdoor stage canopys to extend the sound further into the audience.

Note the panels at the side, which are also angled towards the rear, same as the ceiling panels. This is done to preserve some of the energy instead of absorbing it. This gives more reflective sound energy to the face of the skylines. Also note there are ABSORPTION panels on the wall behind these side panels and around the Skylines. In larger rooms, too much broadband absorption lowers the RT-60 at those frequencys, and makes the sound lifeless. Thats the point of the Skyline diffusors at the rear wall. With very little energy to diffuse, they would be useless. Hence reflecting to the rear instead of absorbing it before it gets there. I would bet this is a great sounding room. There are probably unseen bass traps as well somewhere.

The ceiling deflection things look like the thing i built for my friends side first reflection points(shown here), only a hell of lot more professional.
