I tried searching the forums but I don't think I searched for the correct words. Found some discussions about DIY panels and stuff. I would prefer to buy something ready made or Ikea-style assembly.
Reverting to Google I found a few specialist sellers like:
ATS Acoustics Acoustimac Ready Acoustics Any other ideas? Aesthetics for high WAF is important.
I will need about 12 to 15 panels measuring 2x4ft.
Also drawing a blank on the ceiling options. I have a huge 23x21 ft flat ceiling made of sheetrock.
