First, to Bi-amp the speakers, the jumper or metal bar connecting the HF and LF must be removed. Passive Bi-amping may allow better XO performance of the speakers. I have tried passive vertical, and horizontal bi-amping and no major benefit heard. Using a active xo is better but has a descent learning curve to get things right. To try will not make the sound worse and YYMV.
