The panels look fabulous but to claim it's 'proper room treatment' is stretching it a bit! It will certainly provide some scattering and absorption, but given the felt backing isn't even a centimetre thick I strongly suspect the absorption will work only on the highest frequencies. It should help to break up slapback/flutter echo but don't expect it to provide temporal diffusion or a reduction in low frequency ringing.Thanks - its proper room treatment with acoustic panels, the black backing is 9/10mm hi density rigid felt. They come 2.4m or 3m tall x 600mm wide, I cut them in two, so what you're seeing is 1500 x 600 panels in the pic.
