Since it is a tri-wirable speaker and you have bi-wire cables, you can connect
your cables to two sets of speaker terminals and then you have to bridge -- or run jumpers from -- one pair to another. I would definitely dedicate one pair of leads to the bass and then bridge the other two -- as you suggest. Try switching the other two and see if it works better connected to the tweeters and bridged to the mids or the other way around. Also, the speakers will probably come with bridges. You can use those or you might get slightly better sound by making "jumpers" instead.
