That's not a very good idea.MAJBE 2500 Hz WITH HARD LC TRAP ON THE fs,and multislope...
If you need one... then consider changing your design for the tweeter. Usually a 3. order will work that out.
But, I'm not sure what you're doing anyway...
HI inductor,
why not, excuse me?
I have jet done similar in the past and it works fine and can handle enough power..
In any case I use only 1st order or Subctractive Delayed Transient Perfect filters ( JOHN KRESKOWSKY IS A GENIUS!) in all NEM speakers...
This is why IMHO our spekers sounds better tahn others ...
Jet confrontated with Magico, TAD, Jim Lab,Avalon, Sonus Faber, Chario, Opera, , Thiel ,Vandersteen,Duntech, Dunlavy ed ESLs + active subwoofers...
I HAVE passed 10.00o hours at simulator for x-overs in the last 15 years, not for nothing...
If the midrange can't be employed I simply swap for another more robust with lower Fs...
CHEERS,

CHEERS,
You can do that with the tweeter from the previous post, if I understand it right...(...)

CHEERS,
You don't explain your ideas in full (text) and I'm not aware of your designs.
I expect to be talking about the same things than you...
When you said (a trap in the Fs), I assumed was the tweeter Fs, that kind of design is not a good idea, if not please accept apologies.
The only sensible way to design a crossover is to aim for an acoustical slope. What electrical slope you'll need to achieve the wanted acoustical one is another story. Check for example this speaker where the designer is able to use a 2nd order electrical on both woofer and tweeter to reach 4th order acoustical slopes: Zaph|Audio - ZA-SR71

HI Inductor,
yes the LC trap is at Fs. I hav esuccsefully experimented many times and it works fine
cheers
P.S.. for all : I rest firm on 6 dB/oct slope only,
yet experimentated all possible filters and my listen test are univoque
P.P.S..this is IMHO another Thread : " 6 dB/ oct : do you have never tried it?"

Sir don't get me wrong, I do not mean to challenge you but
a. I went to your website and did not find any products ready for sale, what I found were the some model names like CM0, CM1, FM1, and the statement that your speakers are in " are in early design stage". If or not your speakers are equal to better to others should be the decision of a 3rd party right? We are all expected to biased favourably to our own designs.
b. I assume you mean a 6db electrical slope. If so when a 6db electrical slope combines with the natural slope of a driver the effective slope usually exceeds 6db/oct. The challenge I have found with a 6db/oct electrical filter is power handling and in the case of mids and tweeters excursion.
c. as far as LCR traps are concerned, the only time I tried to use such a trap was with the 9900 (the notch was around 500hz if I remember right - this was in the mid 90s) and I found that the tweeter sounded better without the notch filter in place. Since in the end the sound matters most, I eliminated the notch.
6 true acoustic dB/octave x-overs
Mine experiences with LC or LRC traps are long and 100% positive.
cheers

You are right. time to build final speakers is needed .Prototypes are sounding excellent from 2 months , but patience, please, just a pair of months...

NO,absolutely.
My speakers are all ACOUSTICALLY first order , like Thiel,Vandersteen, Duntech ;Dunlavy ,3A,etc.
We do not have any type of problem with power handling..
in fact we like plays AC/DC live at realistic volume in big room
