This you have in concert halls like Musikverein (Vienna), Tonhalle Zurich, Basel, in many opera houses but not necessarily in the Barbicans or especially in the KKL (Luzern). The sound is quite different with other characteristics.
I don't think that you need really big speakers to reproduce the "rumble-echo". The quality of the low frequencies must be very high otherwise this "noise" will not be recognized as part of the music but as disturbing noise which will hide the sound of many instruments. In concert halls even if there is this "rumble-echo" you can still hear most of the instruments well. With lots of hifi the effect was, let me say it in nice words, not acceptable. I believe the room acoustics have also a big importance but of course if garbage comes out of the system you cannot correct that with room acoustics. I believe that is one of the reasons most people are positively impressed about the sound at my place. But again it is not a question of buying something and connecting it together in 10 minutes, neither in one year. And again it is also a question of personal taste which for me meant to go to lots of rehearsals and analyze the sound there and compare it with what I had. Being critical about the sound at your own place is also a major factor that contributes to achieve your goals. And to be critical also means to accept critics from other people.
