It seems hard to believe, but the driver(s)fed from where you directly connect your single speaker cable (+ & -) will sound noticeably better than the driver(s) fed from jumper connections.
The best solution (as others have mentioned)is a cross type of connection, i.e. connect your positive wire to the positive HIGH terminal and the negative wire to the LOW negative terminal. Then use the jumpers to tie the two positives together and two negatives together.
If you are a non-believer do the experiment yourself. Just try connecting your wire to the HIGH terminals of your speaker and jumpering down to the LOW. Now listen to your system; the tweeter (and midrange in the case of a three-way) will sound clearer and more articulate than the bass portion of the speaker. Now reverse things and make the direct connection to the LOW terminals and jumpering up. The highs will sound softer and a bit blurred, while the bass will be better defined and articulate. Last, use the cross method described above and listen again. Their will no longer be a disparity of sound between the top and bottom of the speaker. You will have better balanced sound, but not what you would get with proper biwiring. You have just averaged the loss across the whole speaker.
This happens on every speaker I have ever tried, even when I have made very high quality pure silver jumpers.
