HIFI Speaker active crossovers ...

For an active crossover to make the most sense, the speaker needs power amps built in. Historically, audiophiles have not wanted that. Maybe views are changing with a new generation.

@ditusa -- According to the owner’s manual, those JBLs have no crossover at all and should be used with a specific external crossover and specific amplifiers.

An active xover divides the signal at line level. For it to work properly, the amplifiers need to be known quantities. I have never seen a speaker that contains the xover but not the amps, though theoretically they could exist. An active bi-amped speaker typically has two amps in it. What model is yours?

I agree, JBL is doing it the right way, rather than putting the xover and amps inside the speaker cabinets. Not the case with such active speakers as those made by Genelec, KEF, and so on.
