I don't use a (real) center, but my EQ is different for HT vs Stereo music for a good reason. The differences aren't huge, but a surround mix tends to sound tonally different than regular stereo. Especially in a room with reduced early reflections.

The Toole measurements posted in the thread I linked before give clear indications as to why, even if it is just part of the answer.


you are correct. adding the center to a stereo sound changes it.


I never do that actually. Im mostly home theater so I deploy each sound to its correct speaker.


Its interesting that you do not use a center speaker - I used to like the phantom center, but after dialing in my actual center I cant stand the phantom center any longer

Not having heard an all out surround setup properly setup in a home I cannot judge that. However I did make sure to get the most pleasing performance even for HT.

The material I listen to is 80-90% Stereo. I have to say the line arrays are quite convincing doing Home Theatre and in a demo I'd surely use one of the startup/racing scenes from the movie Rush. My "Stereo" isn't quite standard with the mid/side manipulation I do either. If I could come up with a non intrusive way to add a center channel I would. Just to see where that would get me. As it stands I'd never get permission from my better half. I count myself lucky that I can get away with the arrays and have permission to add a couple of subs as well as all of this is setup in a normal living room we share as a family. In a dedicated room I'd go wild .

I hear you. I bet those line arrays do a fantastic job. Ive never heard a line array speaker but I would love to.


Yes, I tried doing HT in a shared space for a while - NOT! a good idea lol.


now I have a space that I could basically do anything I want. Painted black, 6x 18" subs, etc. love it.

Having its own space seems probably a good idea for future and going wild : ) they setup more than 25 speakers into this link (see movie) and it probably sounds very nice The Pink Floyd Exhibition „ Their Mortal Remains”.

It must be awful and wonderful at the same time having to mix for so many different sources.
Awful in the sense that it takes forever to really know what you hear and where to put everything, wonderful because of all the possibilities and the ability to change anything at will.

Hi wesayso agree every thoughts you point out there, and thing with so much control is it probably also can be used output kind of fake polished higher performance recordings than was reality at happening, such pleasing edits wont get us closer to truth but it will probably help on producers selling more copies.

Hi Perceval probably because of computer power it looks there is much research into 3d sound these days, in below link a university close to me claims is "replicate the acoustics of any building that exists… or doesn’t", probably its worth a visit to hear claims for sound in London or below university but one thing is sure it wont fit easy in a existing traditional living room.
