Here is the concept:

You have 3 sets of binding posts on your speakers:

- One for the tweeter (usually the posts on top)
- One for the mid-range driver (posts in the middle)
- One for the woofer (posts on the bottom)

The terminal bridges tie all the red/positive connectors together and all the black/negative connectors together. This means you can run just 1 set of wires to ANY of the binding posts and all 3 get the signal.

If you want to send a signal to just one driver, you remove the bridge to isolate it and send the new wires to those terminals.

If you want to Tri-Wire you:

- Remove all terminal bridges
- Run 3 sets of speaker wire (no, they dont all have to be bundled together) from your amp to the speakers.
- Connect a separate wire to each pair of terminals

Your big problem is going to be at the other end: now you have to connect 3 sets of speaker wires to ONE set of speaker output posts on your reciever.

Consider dual-banana plugs like the 279-308 from Radio Shack. They have an over-sized hole that might let you merge 3 wires into 1 terminal.

Good Luck.
