Dear @carlos269 : You speak of ultimate room/system and unique way to do audio things but I can’t see that Ultimate when you have a weak in the low bass foundation of the MUSIC where the " composite " sound is full of those THD and youjust can’t avoid it even with words as " ultimate " that are only words.
The subs you are using normally are incar audio stereos and are competition of JL Audio that has around 6% THD in its home subs so yours could be in the 5% to 10%THD range that it’s not Ultimate.
In your Test bed system things are not better because the TIB subs has a manufacturer spec of -9db FR response at 36hz.
All your " composite " sound is just colapsed like it or not and accept it or not. You can’t " win " against facts, words are only words and nothing more.
You present your self as the unique penultimate top of the top " audiophile " where ( even that you don’t post yet ) the other gentlemans are a " joke ". Good for you.
You can’t validate that " Ultimate " word but you want that the other gentlemans validate their systems when you have not almost nothing because MUSIC has by it self ACCURACY that’s why exist a pentagram and exist the harmonics and many other issues and your systems could be all what you want but accurated in that critical frequency range the more important range in that composite sound.
MUSIC start at instrument transient and the composite sound resides in the low bass foundation. Music halls breath at around 10hz.
I have no problem with your ultimate composite sound that’s in reality is false, at least for me. Yes ultimate has maybe different meaning for each one of us and for me your systems are faraway to be " ultimate " as you brag about.
Good for you that don’t worry about me neither because are your systems, then from where comes that ultimate system brag. I don’t care because it does not exist what you posted here when your premises are just out of that ultimate.
Resolution/musicality comes from accuracy or for you the players play with no accuracy?
Just an opinion .
