Anyone else here interested in, or built, or even heard Folded Well Diffusers??

Yes I do want to learn of the BAD diffusers. But I'm also gonna remove a wall pour a slab and extend the room by 8'. So the dimensions will be roughly 10' by  21' minus wall stud and paneling thickness. It will be another year for this construction project to begin. 
 

The ceiling is 8' with a central ac above or I would remove it too. 

Why couldn't we put low freq absorption and diffusion in a wall especially if building new construction and Taylor the wall stud thickness to accommodate said building techniques? Has this been done before? So my whole wall is a huge panel!

@brunomarcs - yes great idea and yes.
Don't forget to use the Golden ratio for room acoustics

Nope, time is too precious.

Dennis quoted me 3,000 to 4,000 for his carbon technology, says it's the only thing guaranteed to work and I need a lot for my small room.
