Default Gain for 2 Way Bi-Amp


I am currently looking to build my first speakers and I have settled on a 2-way bi-amped design.

The bass/mid is a ScanSpeak 15W/8434G00
Sensitivity (2.83V/1m) = 86.9 dB

The tweeter is a ScanSpeak D2604/833000
Sensitivity (2.83V/1m) = 93 dB

I obviously am keen to not blow the speakers with too much gain! But then I dont want them to be so quiet they are useless.

I also am not sure how to compensate for the 2 different sensitivities of the drivers with the amping/gain. I am looking for as flat a response as possible.

The 4th order Linkwitz design on the ESP website looks great but am I right in thinking that it doesnt provide any amplification, just filtering?

You only need attenuate the input to the tweeter amplifier.
