Thank you in advance for anyone who offers info.
From random bad decisions speaker buying I have these 12" Eminence woofers, I also have some planar tweeters that are good from the 6000 up range.
I don't have experience with testing xo's (or building/designing either...)
Obviously this woofer is made to use up to the 1000hz (or so) range, but given the response would it be possible to use a notch filter in the 2500-3000 range bring the response down & allow the natural roll off to take it to the tweeter?
This wouldn't be hi-fi or anything
Just if there's some massive unknown (on my end) I'm not aware of

You can make any response flat. What will happen at the top, is it will lobe (narrow) and you will find cone breakup. You cannot see the problem clearly with a response plot like this.
Midrange anomalies bad enough to affect the impedance plot are a showstopper for me because it's guaranteed the impulse response will have enormous delayed energy at those frequencies, plus the response plot is smoothed like taking downtown Chicago and plotting a vague bump at Willis Tower.
Seriously, you'd spend more on crossover components to slam down the 15 db peaks at 2.1 and 4.1 kHz along with the 8 db kank at 1.3 khz than a decent little woofer (or fullrange if that's your fancy) would cost, and you'd get actual bass to boot given the 104 Hz (!) resonance and 0.8 mm (!!) linear excursion pretty well ensures the first kick drum hit will have the thing fartin' like grandpa.
Give the guitar speakers to a deserving guitar player and save yourself the heartache.

If you use 6dB/octave slope from 750-800Hz you could get flat-like response within +/-2dB (or so) up to 3500Hz. A coil in series with driver plus zobel for impedance rise correction should do the job.
But, as mentioned by others, this will be far from Hi-Fi.

Awesome
Thanks for the replies, clearing up my unknowns & saving me the waste of time
There are other "bad decisions in speaker buying" projects that will turn out better 🙂
