Center channel speaker placement


I have a 5.1 set-up with my 2 front speakers (rear-ported) out about a foot or so from the back wall and I have my center channel speaker (no rear ports) mounted to the wall on L brackets under a 75" TV that is wall mounted.  Would I hear a sonic improvement if I were to put my center channel speaker on a small table out from the wall at the same distance as my mains?  I have run Audyssey so the speaker distances and time alignment should be correct as is.

You may actually be a little better off as-is.

Against the wall, the C will get more bass reinforcement. You are using room correction, so any extra boominess will be removed, and this will lower the C channel amplifier output.


A better question is, how well do you think the sound is integrated? Do you hear a distinct C channel, or does it flow seamlessly from L to C to R?


Also, C channels tend to have narrow L to R dispersion, so they are not as affected by side walls, an important thing for your L and R speakers.
 It depends on where you are sitting. Regular stereo set up well and listening from the sweet spot already creates such a solid center image no center speaker is needed. Home theater is the way it is because it is intended for a large audience. Without the center channel anyone sitting off axis is going to hear dialog coming from whatever side they are on instead of from the screen. That's why its there. Well that, and to be able to sell more stuff. Stuff you won't need unless you can't sit between the speakers.

So anyway that being the case then the answer is beyond a few general tips like erik already gave nobody knows. You yourself can only try and see.

Your biggest sonic improvement by the way will be when you are ready to upgrade ditch the whole home theater schtick and upgrade to stereo. Two channel gear is so much better than HT just about anything you get will be a huge improvement.

When I am watching dialog heavy material it is very obvious the sound is coming from the center channel.  Where as the sound form the L/R are much more difficult to pin point in the room and I get a good sound-stage and sense of depth from them.  Was not sure if I need to move the CC or do some room correction or if there was a solution to this problem of me hearing all the dialog coming from such a focal area.
