It really doesn't matter as long as they are jumpered. I have a set of Sequel II's and it does not matter. If you were bi-wiring or bi-amping then there are differences.
There are a few things you can try. If they are the original jumpers you can change them. I tried some heavy twisted copper that I made for jumpers and it as a slight difference in sound or you could try some of you speaker cable that may also may a difference.
If your amp has two sets of outputs you could try bi-wiring. That made a noticeable difference on my Sequel's. It was not a eye-opening but more definition and maybe separation between the woofer and the panel.
Give it a try but remember your mileage may vary.
Good Luck
