to the amp. This results in the difference signal being sent to the rears, which is any sound not equally present in the fronts; the more panned from the center image the sound is in the front speakers, the more it is present in the rears. The idea is that the image is determined by the fronts, and the rears are ambient fill. You can wire the rears out of phase relative to each other to further enhance the diffuse sound coming from the back of the room. Believe it or not, it actually works.)
Cool, I was sketching this out, and then it made sense how you say the rears get the difference (in potential) between the two (positive terminals) of each channel.
So you are saying if I have a pair of speakers normally wired to an amp, then just add the second set to the same terminals?
What does the impedance load end up being per channel with all 8 ohm speakers?
I was thinking on a stereo receiver that has an "A" and "B" speaker terminal set. Then if the front L and R are wired normally with the rear pair in series with each other, then in parallel with the two front channels, they could all be wired to just the "A" channel. The other option to be able to add or remove this effect would be to wire the front speakers normally to the "A" terminals. Then wire the rear speakers in series the same way with the positive of each L and R speaker going only to the positives of the "B" terminals. Then when the "B" set is switched on the relay inside the amplifier activates to connect the "A" and "B" terminals in parallel anyway, achieving the same parallel wiring of the front and rear set, correct? With the ability to run normal front stereo, and the add in the rear dynaquad?

i'm the 'publius' btw.
Interesting, so pretty much you are suggesting a horn speaker?
What about dipole or bipole set ups?
One other hitch to the plan...I sometimes will be facing the front of the room while working, and at other times facing the rear of the room while working. Does it matter which end I put the speakers on, if my goal is to get the sound to surround me and not be able to tell the direction it is coming from?
