Peavey to the rescue...  ;D

Here is Marty McCann's article from 1995 that covers running three center clustered speakers from a single bridged amplifier to cover both near and far-fields. I have a hard copy of this somewhere around here, but apparently someone smart decided to put Marty's old papers onto the inter-webs.

Enjoy.

Thanks for that.  I had forgotten/lost it.

Great article. I'm gonna have to read about 5 times to get it all to sink in though. lol

It's an interesting idea, if you need exactly 6dB difference between the outside and center speaker, and if you can't secure the amp level controls by taking the knobs off or using a security cover. I'd rather have control over the level difference. If you are using a DSP speaker processor you can set the gain difference there and leave both channels of the amp WFO, but I don't think it is a big deal to just make the amp controls secure, and keep the wiring straightforward.

How about converting the amplifier output to 70 volt Constant voltage and using a transformer on each speaker to convert back to 8 ohm?   Each speaker would be loading the amplifier and speaker equally?

What is the advantage vs using 2ch with 2 speakers on one channel and 1 on the other? The disadvantage is the poor frequency response of most 70V transformers and the added cost.

Exactly. I have installed "background" systems in restaurants and bars using 70 volt. But, I won't use it as a main FOH system.
