DYI diffuser kits/plans

Hello,

I am long overdue for room treatments. Does anyone know of any plans for creating diffusers and/or absorbers? I have searched the archives and did not see anything. I have also checked other sites. The kits that you can buy seem to be about $100 for a 24X24 panel (diffuser). I am hoping to make my own. Also, Room Tunes, is it possible to build something like these?

Thanks, Paul

I have also searched for info on this but this is the best I have found.

There is enough here to build some but it doesn't give details on how to calculate the upper and lower cutoff frequencies, just some examples.
More to discover
