I used to own tri-wired Alons. Used their own tri-wire cables, and some I made from DH Labs stuff. Also tried them bi-wired. Most of the related articles indicate the benefit to bi-wiring comes from separating the woofer cable from the MF/HF cable(s). Therefore, you might try a typical bi-wire cable with the LF wires (if they are different as some are) connected to the LF terminals and the HF wires connected to the MF or HF terminals and then those two sets of terminals (MF and HF) jumped together, preferably with good quality jumpers similar to the cables you are using or with a decent piece of 18 awg or smaller wire.
