HI Rich, I have the same speakers and a pair of Supertowers.
Just to manage expectations, there isn't a detailed 'manual' for these speakers. You'll find a simple piece of paper glued to the back, which primarily covers bass damping adjustment and speaker placement suggestions.
Regarding the bi-amping...well, it's not gonna gain you anything. The "problem" is that, because of the quasi-second order crossover along with the series and parallel wiring of the woofers, the biamp part of the crossover is between the mids and the tweeter, not between the woofers and the mids. Therefore, you'll have one amp running at about 90% of the power and the other at about 10%. If you are looking to gain some overall power, you are better off bridging your amps instead if you can.
