I've heard people swear by installing one conductor on the HF and one on the LF in a diagonal pattern and then using the jumpers. I guess the only right answer is: Try them on the LF, then on the HF, then diagonal, and then diagonal reversed and pick the configuration you believe sounds better. You can't hurt the speakers, you'll be tweaking all night, and it won't cost you a penny. BTW, most aftermarket jumpers are way better than what the factory provides. I have Quads 21L's and the difference when bi-wired is quite noticeable (for the better).
