Biwiring Triwirable Speakers


I recently got a pair of Wharefedale Opus 1 speakers, which have tri-wiring capabilities. However, I am using 4 conductor speaker wire. Should I separate the tweeters and link the midranges and woofers together, or separate the woofers and link the midranges and tweeters together? Thanks in advance for any advice.
