18 months late, but I’ve had biwireable Model 1’s (pre-signature) and I am currently running Forest Signatures. I have experimented with a variety of wiring options on both, from ‘true’ biwiring (separate runs for tweeter and woofer), to internal biwiring (one run of speaker cable with 4 terminations at the speaker end), to several different aftermarket jumpers, wires connected diagonally, tweeter jumped to woofer and woofer jumped to tweeter.
After much anguish and a LOT of time (not to mention $$), I decided that the FOR ME, IN MY ROOM, ON MY SYSTEM, the purest sound is obtained in the most conventional way - speaker cables connected to the woofers, using the Totem supplied jumpers. Even though they just look like bent paper clips, Vince Bruzzese told me they are in fact solid silver-plated copper, and they are intended to allow the crossover to operate as intended (unlike the cheapo brass plates included with many other biwireable speakers).
Although they look less sophisticated than some of the other options (not that anyone is looking at the back of their speakers), Vince’s explanation makes perfect sense to me - no extra connectors or dielectrics or anything else that could alter the performance of the crossover, however slightly. I imagine that the bare speaker wire through the bottom to the top option mentioned by a couple of previous posters would yield a similar result, but the way my speaker cables are finished makes that difficult, at best, so I have not tried it.
YEMV, etc.
