If you have a nice system why do you really need room treatments?

"Adding an additional absorption panel in a 20 x 18 room that’s furnished is extremely hard to discern. Maybe Superman hearing would do it."

"Reaching to a textbook to help figure out whether a situation sounds good or not may be helpful to some but I trust my ears to tell me what’s going on.....My curve for the subs seems perfect, I guess you could say this is a helpful confirmation but I really didn’t need to see it based on what I was hearing. I’ve learned to trust what I can hear."

One minute you state you need Superman hearing to determine the impacts the next you’ve learned to trust what you hear. You constantly contradict yourself ,and frankly dig yourself deeper in the lack of credibility hole.

This thread was utter nonsense from the start and has only gotten worse and more pointless so why keep adding to it?  Please just let it die. 

So I guess treating a room with acoustical panels Will provide a benefit. This is news. So many great enthusiastic people have led me to rethink my position. I thank everyone for helping me overcome my fear of adopting a more liberal view about acoustical treatments.

Now if only someone could help me deal with Leaf blower noise throughout the day from neighbours who are too lazy to deal with lawn issues with a rake. And just why are we using leaf blowers in the middle of the summer when there’s no leaves? Because blades of grass somehow have taken over. Proliferating use of leaf blower noise is a serious problem. Ever noticed bird populations have declined quite a bit and a lot of it has to do with leaf blower noise throughout a community. Further if you have allergies they are probably a lot worse because of all the leaf blowers kicking up so many particles. I’d mention the environment because of the gas powered Leaf blower engines but people don’t care about the environment much anymore. They can't use mufflers because it would impact the flow of air and we wouldn't want that to happen.

I haver at least a decent system (see my profile and decide for yourself). My modest addition of some acoustical treatment in 2023, consisting of some absorption panels and some diffuser panels yielded a surprisingly pleasant and budget friendly improvement (the cost of the absorbers and diffusers was less than the cost of just one of the balanced interconnects I use between various components). 

YMMV
