Question about Active Bi-amping

Curious about Active Bi-Amping.

My understanding is that to setup an actual active Bi-Amp (with compatible speakers), you would need either 2 mono block amps per speaker or 2 stereo amps and a External Crossover?

Would the Crossover in the Speaker need to be bypassed or removed?

OR

If you were to do Passive Bi-Amping, you would connect each amp directly to the speaker terminals but how would you connect the Amp Signal connections back to a pre-amp or Integrated since most are only have a a simple left and right output?

Thanks

                                        ---amp one---to tweeter/midrange

preamp---to crossover                          

                                        ---amp two---to bass

Hey OP.

Your count of amplifier channels is correct.  You would need 1 channel per driver.

In an ideal situation, the speaker crossover is entirely removed.  However this is complicated for a number of reasons.  Crossovers are more than just frequency filters.  They also provide level matching and equalization.  DSP crossovers are supremely convenient for this as they can do all that plus delays.

I suggest before you experiment on anything fancy consider a simple test rig to learn more about this.  Get a pair of inexpensive 2-ways or kits, a miniDSP and a pair of cheap amps. 

Best,

You would need 2 Y-Adapters!
