Centre Speaker: is it possible to cheat?

I have a mid-range stereo system. I also have an old "monster" Tannoy speaker. I'm not too keen on replacing everything and moving to a 5.1 system, so I was wondering if I can cheat by somehow wiring the large box into the system as some form of "psuedo-centre" channel - it is big enough that it is also likely to act as a half-way sub! My amplifier does not have a centre output - can I do some clever wiring to drive the centre box?
 
Not with a stereo system, unless you want a very unusual sound. It is possible to use a second set of speaker terminal, but I'd not recommend it, as there would be no centre info (often speech, to anchor dialogue by a screen), just a 'difference' signal that would detract from the stereo image.

And if it played out of phase, it would tend to cancel what bass you currently have.

Better to find a 5.1 amp/receiver and use a DVD source.

If you are curious what the Tannoy sounds like, it would be OK to put it on one channel instead of one of your current pair, then you could compare the sound with the amp switched to mono.

Hi Tonyperris,:wave:

To be honest I don't think you have much chance of using your tannoy speaker. As you don't want to go for 5.1 I would look at getting an active subwoofer to match your existing setup and go for a 2.1 sytem. If you give details of your current kit I am sure that someone will be able to recommend some suitable subs for you to audition.

Cheers

You could consider something like an old Yamaha DSP-E800. This is a 3 channel processor/amp that adds the centre & rear channels to a stereo setup. It's not going to support the latest bells & whistles but will only cost you around £50.

Yes,you can if your amp is transistor.Just use the left positive and right channel positives to feed your Tannoy.It will play the sound you"hear" coming from the middle.This is the source of cheapo disco lights which are wired the same way and vary in brightness according to the sound.For more info. google Hafler Effect.

I really wouldn't wire in the Tannoy across both channels you may damage your Amp, even if it works without causing damage I doubt that it will sound any good. Be careful.
