Is my center channel too high?

I recently mounted a shelf on the wall, behind my RPTV.

I mounted the shelf and center channel such that the speaker is about 6 - 6.5" feet high from the ground.

My listening position or ears are about 3.5 feet from the ground when I'm sitting. The tweeter on my floorstanding speakers is about the same height.

Now, I do have my center angled downward to the point where its aiming at my face.

Is this an issue?

Ideally your left, right and center will all be at the same height - 3.5 feet off the ground. With TV's it's usually impossible to have that ideal position. You should be fine with your speaker position.

Of course, the only person who can really answer it is you. Do you like the way it sounds? Does it sound like the sound is coming from too high? If it isn't bothering you, then don't worry about it. If it is bothering, then try putting it lower... maybe on a stand in front of the tv and aim it up...

Try it at lower levels and see what you think. I'd put it where it sounds the best to you.

Invest in a SPL meter [Sound pressure level] Radio Shack. inexpensive . The digital meter is a little more expensive but well worth it cause of ease of reading and use.

Aim the SPL at the speaker at diff. levels where you sit and see what you have and where for max pressure. Also set the meter on something at ear level and play with the angles of the speakers.

THe SPL meter is a very useful tool for setting up audio once you get used to it and all the uses it has.

Of course I'm assuming you don't have one because you would have used it already..

If you are concerned about axial phase and stuff like that {which most of us can't hear] don't. Unless you want to become obsessed.

Luck, BEAR!

Besides if you leave enough hints around SANTA may bring you one.

Some actually advocate that it's better to have the center above the screen than below, because we can't localize sound as good from higher up compared with below. It's not at all a "problem" as mentioned if you calibrate, and aim the speaker properly things should sound just fine and not be too distracting that it images off-screen. Your eyes also dominate, so most of the time you'll think it's imaging on-screen anyway as you're watching a movie. You could always try below the screen, but I predict it may be worse if anything.

"behind my RPTV"...????

sounds more like a possible issue...than the height ...interference-wise.

I believe he means behind in the vertical axis.

Chrisswiggles is right about localizeing up high.

Thats why we have to look to see were the airplane is.[deplane]

I know what he meant...

And reflections/diffractions off the top of the TV can be an issue...if the speaker is not forward of the screen plane. [it obviously will depend upon the height of speaker, height of TV and distance speaker is behind the screen plane, and listening distance.

His TV is 27.5â€ deep [assuming it is shoved against the wall]

I lowered my shelf mount about a foot and it made little difference in all reality. It seems to slightly feel like it's coming from the screen a bit more now, though that may just be psychological.

If it sounds good, should be fine. A nice test would be a scene where someone walks across a room talking, or a car drives from right to left. If it seems like the "image" of the sound goes uphill towards the center, then back down when it hits the far channel, your center is noticably ill-positioned. As someone else metioned, it is best to have all the tweeter/midrange drivers positioned at the same height, for the best sound.

I have my CC at about the same height over my Toshiba RPTV and it seems to sound fine. I really could not have put it anywhere else!
