It would be an interesting blind test to do between Active and Passive as the only difference. We have a switcher that allows us to switch between two different crossovers to the same speaker and we have a switcher that allows us to switch between different DSP codes to the same speaker. With some modifications to our switchers we should be able to do both simultaneously.

What we do know is that the difference between an LFR1100 Passive and an LFR1100 Active is not only about Passive versus Active. When designing the LFR1100 Active I wrote DSP code that replicates the passive LFR1100 Family of Curves in an Active speaker. I did this so we could do blind testing between the Passive and Active Family of Curves. So we do know that putting very linear Listening Window and Sound Power curves on top of each other wins the blind test.
