Anyone who asks Why biwire? will eventually get the response: I've yet to hear a reasonable explanation how it could be advantageous. When that explanation is supplied - biwiring isolates the current passing to the different drivers and allows you to select gauges especially suited for each run - you'll hear that the advantages aren't really advantageous and it's all marketing and nonsense. You've already gotten the best advice - try it. Then rest easy knowing you've exploited the full potential of your speakers.
