So, rather than deadening the whole back wall... I will be adding in some deadening and some diffusion.

I kind of feel like this is a blind stab... but it seems like there is enough agreement here to go ahead and give it a try!
yes... this is a some balance between two opposite (non very functional) extremes ...
It will works...

This entire unit will basically be free standing right against the center of my back wall... the back wall has 2 large windows that will impede my ability to mount the diffuser directly to the wall, hence the reason it will need to be free standing.

Does that make better sense?
Yes, I understand now... and it is ok.. this will works.

I really appreciate all of your input. Fingers crossed!!

I think the hardest part will be taking the time to make this look good...


Now if I can just find some spare time!

Boggy -

Question for you about the slats. I'm trying to keep the overall weight of this thing I'm building to a minimum. Do you think that wood lattice that is about 1 3/4 inches wide and 1/4 inch thick (which is roughly 4.4 cm wide and .6 cm thick) is to little? There are other pieces of wood available that are thicker and wider, but the weight factor is probably triple.

Thoughts?

I use wooden slats 5cm x 1cm now, in current project...
4.4cm x 0.6cm is also good.

I'm trying to hit a sweet spot between "ideal size" and "ideal weight".

Since I'm putting a lot of time and effort into this... do you think I should go to bigger slats? Or do you think it really doesn't matter?

I don't think that you need a bigger slats.
I use anything between 2cm and 8cm (width), and anything from 0.5cm to 2cm (thickness). My criterion is always a price and aesthetic look.

If I need something much serious, much complicated and much better than binary, I will go for design based on Schroeder principle...

Would you give an example of that.
