How much investment is wasted on front left, right channels as center does a lot of work?

34 replies

I need a little help deciding weather to use my Beolab 9s as part of the surround sound for the TV, or put them in my bedroom or office and use them as good music/stereo speakers. Im trying to make the best use of their potential, as I am fortunate enough to have acquired a pair. (I also acquired two sets of BL 8000s and a set of BL 6000, of which I need to sell one set or another as a compromise with the wife) 

Iv been wondering how much audio is played out of the front Left and Right channels in a surround sound setup, when considering that the AV surround processing tries to give a lot of work to the center channel. From my understanding, AV processing will try to put most of the dialogue to the center channel, along with other central sounds.

We have seen questions on the forum, on people asking what speakers to get, it would appear that less financial emphasis is put on back channels, and even slightly less for left and right surround. The idea being that these are just more sound effects to help with scene emersion, rather than essential channels up front.

My question is, if one were to use... say, Beolab 9s, for front left and right channels, are these speakers wasted, as the AV processor is only sending miscellaneous sounds, while the vital stuff, (dialogue, central scene sounds) is intentionally being isolated and not sent to all these speakers, sparing that sound only for the front channel?

Conversely, is that reason to persue an ever better center channel than one originally might be thinking? So, in my case, I was considering Beolab 4000s as centers, ought I be considering Beolab 3s instead, if only to make full use of the Beolab 9s in that the center is "measuring up"?

Or am I mistaken? Is more sound than one might think sent to the front left and right channels? With a good quality pre-amp, CD player, or Gramophone player, I could setup a nice music station that will make full use of two speakers in simple stereo. On the other-hand, my whole family watches TV/Movies daily, so the BL9s will physically be made full use of, if not full potential use of.

Any thoughts on what I might consider?

As center you should have a Beolab 7.4.

No sound is wasted, the left and right front is vital for the sound.

In your case I would use the 6000’s as rear surrounds, and use the 8000’s as office speakers.

What surround processor are you using?

I think there is a forum member that has a Beosystem 3 for sale 😕

My advice in situations like this is to think carefully about which speakers you prefer and then reluctantly sell the wife.

Since you are not telling us which tv/soundprocessor (or BV) you are using, it will be hard to give any exact advice!

Are you upmixing (tv programmes etc in 2 channel/stereo) or are you using the native multi channel sound when avaiable???

Generally no speaker in a proper multi channel setup is wasted - all channels are there for a reason.

If you really need the 9’s in your bedroom, then go for it and use the 8000 with the tv.

Otherweise - the 9’s are mighty L/R speakers in a 5 channel setup!

Don’t you listen to music/2.0/stereo in that room?

Hi Howzit,

I agree with MM, good speakers are never wasted! 

I would say the key question to ask is "which room is the priority"?  If you really enjoy listening to music in the bedroom and this makes up the majority of your listening time, then the answer is simple - put the best speakers there.

If your viewing choices are generally dialogue based (eg. news broadcasts), then a centre speaker alone is probably fine.  For full-on action movies, adding front and rear surround speakers and a subwoofer will transform the viewing experience by spreading the sound around you instead of focusing it from the TV position.

Or if you are unsure, why not try the Beolab 9s in each room in turn and see where you like them best?

Kind regards, Steve.

I love my 5.1 system and when not watching movies or extravaganzas like GoT we listen in 3.1.

The BeoVisions are designed to handle all of this up and down mixing as explained by Geoff in these two articles (and probably others on his site)

At the moment, I do not have a BV. After the most recent round of acquiring speakers, I will have to wait a while before I can make that happen.

For a receiver, it’s the same situation. I will be using a Yamaha CX-A5100 pre-amp I think (or Yamaha RX-A3070)

I have had an LG OLED for a while, so I’m cobbling something together that ensures all latest HDMI, Atmos, etc is passed through. The Yamaha’s have all the latest bells and whistles, including the pandora, Amazon Alexa etc.

I’m primarily a tent-pole movie watcher, so all the marvel movies, mission impossible, transporter etc.

It’s been a bit of a confusing journey, but at least the last leg for now is the center channel. Bouncing back and forth between BL4000, BL3, BL7.4, and even contemplating Beoplay A9 as a center speaker, simply because of my decor setup. Speaking of which, is that an absurd idea... the Beoplay A9 as a center?
On looking up Beovisions (Iv never really looked at them), the idea is a very attractive proposition. The built in processing and phenomenal center channel and connectivity for the rest of the speakers, along with being a general audio hub.

Unfortunately the ones I found that I would be able to afford is a BV5,(with an ALT) a BV7, or a BV10-40

This seem a little too long on the tooth for consideration, correct? I presume the BV5 isn’t even 1080P.

I’ll read up a little more on these
Or get a Beosystem 4 plus Screen (no need for B&O here). Check Beolab 7-1/2/4/6 for center channel.
