surely there is someone manufacturing QRD diffusors here ?bloody dear to ship from the USA $599 +shipping =expensive

REALTRAPS DIFFUSORS
The RealTraps Diffusor ($599.99) is an extremely clever product, and it has fast become one of our best sellers. This unique design marries a high performance bass trap with a genuine QRD "well" diffusor that's effective down to the low midrange. It transitions from diffusion to absorption over the range between 400 to 800 Hz. The RealTraps Diffusor can be easily installed on a wall or ceiling using the supplied hardware, or mounted without harming the wall using either of our attractive stand models.

If you're even slightly handy and have some spare time you could make some for a very small fraction of the cost.

That's even less work, $599+ seems a tad ridiculous. Might have a chat to a cabinet maker friend and go into business!

In most normal situations, its not possible to diffuse lower frequencies because their wavelength is too long. The realtraps version combines a QRD diffuser with one of realtraps membrane absorbers. It's the best of both worlds, absorption of the lower frequencies, diffusion of the higher frequencies. It's probably well worth the price tag.

I built my own QRD diffusors, time consuming but they look excellent and I get lots of compliments. There are various websites with formulas but I'm overseas right now and dont have my notes. I ended up with 2 pairs of panels going down to 400hz 2 pairs down to 900hz and 1 pair down to 1.5k. Easy build with standard pine and mdf.
