Biamp question

I do have one last question. I am assuming that both amps inputs go to the same preamps outputs. Is that a correct assumption?

Yes! 

Doesn't your preamp have 2 variable stereo outputs?

If so, just connect one amp to each (no need for a Y-Splitter).

And I’m pretty sure I am the most confused person in the room right now. 

I looked up your loudspeakers, they are designed to be bi-amped. Just take the strap off of the speaker terminals. They will work with or without a crossover but the proper way is with. 

oldhvy is correct in the bi-amp method, but an active crossover like russ69 mentioned is the better way to do it. You can limit the bass going to the mid/high frequency amplifier, reducing power and intermodulation distortion. This will make both the low and mid/highs much cleaner. An active crossover will also give that much greater ability for you to match the levels of each band. So many crossover choices, from DBX223, TDM24CX-2, many Ashley’s up to the Marchand, Bryston and First-watt at the top, in my opinion. You also have the choice of digital, Behringer and so many other DSP’s. We are all here to help, good luck!

Thank you all! I believe I can manage the active crossover (possibly) but my chief concern is disabling the crossover in my speakers.
