The last response prompts another thought. (Although my comments should maybe be in another thread.)

A lot of folks simply replace the factory provided jumper with a good quality speaker wire. Some report that it provides a notable difference. While I haven't done this to my Monitors, it makes sense. Both the treble and bass sections of the speaker will see the same consistent sonic signature provided by the wire. (I think I'll go home tonight and do this.)

This isn't the same as bi-wiring, but is sure would be simpler, cheaper, and cleaner looking (of course, maybe some like to see multiple wires coming into the speakers - my wife doesn't).
