Yes, I have tried this and in my opinion it does sound different than
stereo. I've taken it one step further by adding a third cabinet which is
wired across the two positive speaker terminals on my stereo power amp.
This results in the third speaker being out of phase (?) with the left
and right cabinets which gives it it's own voice. Some very interesting
stuff comes out of this third cabinet on occasion. I've used this set up
for years on both my rig and my stereo system and I haven't fried
anything yet. Maybe I'm just lucky? Actually, I read about this idea in
Popular Mechanics or something back (again, yup i'm over 25) in the 60's
as a way to make a regular stereo quadraphonic. In the article they had
the forth speaker wired between the negative leads from right and left
and the negative terminal on the amp. I wasn't so impressed with this
part, couldn't hear any difference in the voice of the fourth speaker.
So my rig's set up like this: clean signal into amp @ center; line
out/effects send from amp(s) to mixer; mixer output to loopers (jamman
and digitech time machine); loopers outputs to 2nd mixer w/ vortex and
digitech studio twin on effects loops; mixer output to stereo power amp
w/ speakers @ right, left and third speaker @ back of room or hall.
Both the vortex and the studio twin essentially have the ability to
transform the mono signal from the loopers into stereo so I have four
seperate/different sound sources...surround sound.
