shatki holographs


For those that have experienced these, do they really work? If they do , do they treat they entire audible frequency spectrum? Can they be DIY effectively? How do they compare to other acoustic room treatments? Thanks.

Yes, they can be done DIY. Quite easily if you have the woodworking tools and appropriate skills. Others have made them DIY and they reported very good results.
