Crossover Point Advice?

Gday members .

I’m making a 2 way bookshelf speaker blah blah this blah blah that

Below I’ve attached the freq response for the woofer driver I’m using. We can see breakup around that upper 4khz mark all the way through to 6ish kHz.

I understand notch filters and a 4th order crossoverol to really “nuke” that breakup should be used however I’m trying to keep things simple and cost effective (to an extent )

I think if I crossover @1.5khz or even 1.35 (yes my tweeter will be happy to play that low) with a second order LWR crossover , which as we know is 12db/ octave I will just miss that cone breakup, and I shouldn’t get any significant performance decrease, what do you guys think ?!

Thank you in advance

12db/oct crossovers will have a slight dip or bump in the FR, depending on the overlap, because it isn't a true -6db near/at the intersection.

Other than that: "it should work"

It should be quite reduced, like maybe 20 dB down. Plus, the breakup seems "smooth" not ragged (assumingthe measurements themselves are not smoothed). So I'd go for it and see how the results come out. It's not like you would be stuck with that crossover until the end of time.
