Hiya. I know that the centre speaker needs to be placed on top of the TV or
just below it, but I have a TV (an old Sony Wega Trinitron KV-27FS12) with a
top surface that isn't parallel to the ground. There's a gentle slope
downward, just enough for me to worry about a speaker falling off if
somebody bumps the TV. Also, that top surface is just under five inches
deep, and the inch closest to the front has six function buttons (TV/video,
channel up/down, volume up/down and power on/off) and I don't want to cover
those up if I don't have to.

Behind that five inches, is a tiny cliff, then it slopes downward, so if I
put the centre behind that five inch surface, it would be angled up at a
small angle (I'm guessing it's maybe 15 degrees), and it would be resting
against the wall (just over a foot behind the TV screen).

Placing the centre speaker below the screen is impractible; there's simply
nowhere for it to sit.

I've considered mounting it to the wall behind the TV, but that's a good two
feet behind the screen! Will that two foot distance make an audible
difference?

Or can someone suggest a more practical solution?

many thanks to anyone who can help,
vij

Can you control the volume of your center channel through your amp or
receiver. If so, simply try to compensate for the distance by
increasing the volume. The only other problem is rattling and
vibration that you might get by placing it in the location you
indicated. I have mine just below the screen and the sound is
"transparent" as far as the source of the sound is concerned.

Your amp will probably have distance settings for each speaker. That's
the most common way to compensate.

Audio does about 0.03s/m, but the amp will work with metres/feet,
making it easy to adjust.

I just remembered that the receiver I'm planning on buying (Yamaha RX-V750)
has a parametric room acoustic optimizer, and it measures the distances from
where the listener is to each of the speakers, and adjusts everything
automatically. So I think the idea of mounting it to the wall above the TV
is probably the best option.

Thanks HTEnthusiast and Gert for your help!

What a coincidence. I've got the little brother (650) and the
optimizer mic does a great job. I just love the pure direct function,
making your stereo material sound pretty good for the money.

Let the Yammie warm up a little before you play your Pink Floyd cd's.
It makes a difference.
