thank you for all the replies so far, for my newbie questions.
does crossing over a tweeter with a low Fs make the mids thinner?
i get that they might be more detailed and faster because the tweeter will take over the mid woofers duties at the higher freq.
but due to the smaller size of the tweeter will it make the mids a touch thinner and thus not the best thing to crossover a tweeter too low even if it has low resonant freq ?
thank you again!

No, it's not like that. If anything crossing the tweeter too high makes the mids thinner because the woofer doesn't produce them in the fullness of space. It's not a matter of the tweeter being faster because it's lighter, that all happens at the top end of its response and it just goes more quiet.
How much mids can be produced by a tweeter has to do with the spectral response of pink noise, and the maximum power response of the speaker. I own tweeters RX22 HF that had frequency response 500-20000 hz and power limitation 70 W rms. In the 1989 SP2 crossed at 800 hz the power limit was 175 W. In the 1999 SP2-XT with crossover 1200 hz the power limit was 300 W. In the 2004 SP2 crossed at 2000 hz the power limit was 500 W.
In the 1999 version the SP2-XT was specified -3db up to 22.5 deg off axis from 500 hz to 14 khz. In the 2004 version the frequency spec was -6 db up to 45 deg from straight ahead. In the SP2(2004) the box was built like a trapezoid, 8" narrower at the back, to force the 15" woofer to spread 800-2000 hz up to 45 deg off axis. The previous models the boxes were rectangular.
Tweeters not loaded by a 14" wide horn may not have equivalent off axis response.
