Do you ...Center Channel?


Hello,

To me it is difficult to set a center speaker in the living room. Underneath the TV would be too low. On top of the TV (LCD) would be unpractical because in may case the center channel would be fairly big and heavy.

I imagine that most of you, living in homes with a dedicated room, you have no issue. How about all the others like me, with limited space, would you have the center channel at all and go with a four speakers setup and set the preamp to 'No Center'? Or would you compromise in some other ways?
Thanks.

If your speakers are set up for multichannel, the left and right are too far apart for stereo. With a 2-channel source like a CD you must come up with a center signal/speaker, or be faced with moving speakers around when playing a stereo recording.

I have yet to find a 2-channel recording that is not improved by using a center channel. This is not true about matrix-generated rear channels, although a very few stereo recordings respond well.

The front speakers are 52" tall. And the center would sit well below. My impression is that the oratorio was designed with the HT in mind more then the MC music. So far I am listening multichannel music with four speakers.

Provided your DSP is adding back in the Center channel information to the L and R main speakers (phantom) then you are certainly doing the right thing in your case, IMHO.

A perusal of most recording studios will show that, for those with a surround setup, they all seem to prefer to mix/master with five speakers of the same type, with the mid range and tweeter drivers all at the same height.

At the end of the day, you have to ask yourself how many people have you ever seen listening to stereo with Left and Right channels at different heights from the floor, or one speaker turned upside down and the other the right way up?

Common sense should tell you what is best...inspite of the marketing hype and sales people which often advise differently on a center channel.(I wonder why?)

BTW: Kudos to Rives for telling things like it is, which just shows that some companies can be trusted to look after their customer's best interests....these companies obviously seek repeat business and word of mouth recommendations, rather than focussing on one time sales!

OTOH, creating a phantom center when there is a discrete center signal creates inevitable phase/time errors in the process. This is noticeable even on-axis but mostly with music sources.

Really? How?
----------------------------------------------------------

The 'phantoming' is a purely algebraic process in which the center information is electrically split between the L and R channels. As a result, sounds which reached the center microphone at a different time than they reached either the right or left are now combined into a simultaneous signal and reproduced from a single speaker. Such center sounds will be reproduced from an inappropriate distance and/or the incorrect time and they will also interact, electrically, with similar (but significantly different) signals in the left or right channel resulting in unpredictable summation/cancellations.

Or move your seat. ;-)

Good Point...obviously the lack of center channel is a form of compromise, otherwise studios would not mix 5.1 with five identical speakers of equal height.

However, having a center channel at a different height from the main speakers is surely a compromise too, This was Rives point, I think, as our ears have a pretty clever way of sensing the direction of sound (try covering one ear and you will still find you can tell if a sound is above, below you ,to one side or behind you....amazing but you can). Since most setups (plasma/LCD/CRT/rear projection) preclude the option to match center channel height to the other speakers (unless you want the odd impression of the sound to come from below or above the image)...surely phantom center is a pretty solid sensible recommendation in many cases?

I agree, however, that if you can place a center channel speaker, at the correct matching height, behind an acoustically transparent screen (for example) then you certainly have a much better setup than one without a center channel and using phantom - this is without doubt. (But how many people have this option available compared to those with plasma/LCD/CRT/Rear Projection?)
