I also have a pair of Unifield 3's. These speakers must be either bi-wired or jumpers running from the Sub-woofer to the mid/tweeter driver module. If you are planning to use jumpers, the mains go to the Sub-woofer. Additionally, I have found that these speaker work best with pure cooper speaker cables.
Hope this helps.
BTW IF you are looking for a set cables, I have some DIY bi-wire cables that might work for you and we could make a deal on. Please IM me, if you are interested.
