If Audiophiles care about sound, then why so few threads on acoustics

dmaddox77, the two side walls "may" be best and this is often what is recommended, mainly based on math simulations done by Harmon and others. Problem, is, almost all (all) those simulations assume no output from the mains and and one of your primary modes (~50hz) will still have your mains putting out a lot unless you high pass filter them. This is where measurements really help.


Heavy carpet everywhere and more absorber panels may leave your room over damped. Would need to be careful. Need to balance diffusion.

So, it becomes an interesting puzzle to incorporate aesthetically pleasing (or "invisible") acoustic treatments in a shared living space.

One of the manufacturers of acoustic wall panels, I forgot which one, offers customized design. If I understood correctly, you can send them a picture and they make a panel with it. You could pick a color only and make interesting designs on the wall, or your kids' paintings, or whatever else comes to your mind.

Since time and effort is a commodity that many don’t have enough of, as several have pointed out, there is a need for some expert advice. The problem becomes that most expert advice is tied to sales of a particular solution. And there isn’t really a profession dedicated to consumer audio acoustic consulting. (Of course!) I am now wondering whether my local university, which has a sound recording department in the Arts and Media college, might have a professor who has the training for this. If they did, and were willing, they might be contracted to come to my house and consider my situation. Perhaps that’s an option for others, here. 

Heaudio123, I am afraid it will be too dampened as well.  I will put some scatter plates on the rear wall and rear sides.
I love good quality sound, so my system will always evolve.  New and better speakers, subwoofers, and amplification will increase.  At this point diffusion on the cieling will be added.
