The voice coil wire stays the same..

And what if you get rid of that earwax - does it still sound the same?
How about replacing the crap you have for audio system with something decent - still the same? Why don't you try, and get back here, when you have something useful to say?
Test your ears and your speakers too:1) Bi-wire your speakers in the normally prescribed manner (two sets of cables per speaker/all terminal jumpers removed).
2) Play some music. Make note of the sound you are hearing.
3) Turn off your amp and install only one jumper (across only one half of each speaker's terminal set) per speaker. Turn back on, listen to the music again. After comparing the new sound to the sound you heard the first time, can you hear or remember any difference between the two? If so, then you know you have "bi-wire compatible" speakers and you have ears good enough to be a "bi-wire compatible audiophile".

I'm trying to figure what circuit that would create now...to connect one jumper
I noticed some people would have jumpers in place but wire one polarity to the lower left and the other to the higher right - creating also a "circuit" but one slightly different than just using either the lower or higher pair of speaker posts
Again this is interesting to me since I got something I did not expect which runs against the idea of the placebo effect - I really didnt expect to hear anything better but it certainly seemed that I did

"GenungoTheJust" says:AA inmate and electrical engineer John Risch (now a Bored Member) was the one who first alerted me to "single jumper bi-wiring" many years ago. I'm not clear on the technicalities but, obviously, altering the ground path in this manner can produce audible results (at least with some speakers). Search the archives here for John Risch's posts if you are really interested.

For some of the science behind bi-wiring, see the following links:
WARNING: THE ORIGINAL GEOCITES SITE NO LONGER EXISTS, THESE ARE LINKS TO A GHOST SITE, THAT ALSO HAS POTENTIALLY DANGEROUS PAGES FOR THE UNWARY, BE CAREFUL WHAT YOU CLICK ON!
If you stick with the links as shown, and those pages that are logical extensions of the page you are already on, it should be OK
http://www.geocities.ws/jonrisch/biwiring.htm
http://www.geocities.ws/jonrisch/biwiring2.htm
http://www.geocities.ws/jonrisch/biwiring3.htm
and a portion of my AES paper on a new test tone that was also used on cables:
http://www.geocities.ws/jonrisch/page7.htm
this page has links that take you to pages 8, 9, and 11.
The first link above has a text description of what bi-wiring is, and how it works.
The second link goes into further depth on the how, and has wiring diagrams and charts of inter-driver attenuation that show just ONE of the benefits of bi-wiring vs. single wiring.
The third link shows response graphs of what happens when the woofer drives sound into the tweeter, and vice versa, as well as when other speakers in the room cause a signal to be developed across the terminals of a speaker in a speaker system under examination.
The page 7 and following page's links show IM distortion being reduced via the use of bi-wiring, as well as provide graphs showing the division of current flow in a bi-wire situation as discussed in the first link.
One note: my e-mail is not at strato.net anymore, it is:
j_risch@bellsouth.net
This link:
http://www.audioasylum.com/audio/cables/messages/13441.html
is the one concerning jumpers at the speaker with bi-wired cables.

I've tried most types of bi-wiring and single-run wiring schemes and I think they all sound slightly different. Everyone should try every possible wiring scheme at least once if they can afford it.
jumping the negative posts on each speaker

Sounds like you are describing jumping across from one negative terminal to the other per speaker. Have you tried one jumper per speaker, but jumping "upwardly" (from positive to negative)?
Any differences heard?

Jumping "upwardly" or vertically is the same thing as jumping from "negative to negative", at least with most bi-wirable speakers. We're both talking about the same thing. Hyuk!

you said connecting positive to negative.

Oh well, I guess we'll never know what it sounds like. Thanks, anyway.
