I still hear a lot of ringing and some sort of metallic sound do i need to redo the crossover from scratch?
No just covering each driver, i think the paino, guitar and cymbals etc sounds ringing/metallic
I am.coming from dc28f to rst28f both are silk dome but to me rst sounds harsh
It has been my experience using a Morel tweeter with just a single resistor in series that exhibited the same "Ringing" a simple fix was to add another resistor of approximately 22Ohms 5Watt in parallel. Sending the "Harsh" resident noise to ground! Here you will see a link to the image that describes the network. Apologies if someone has submitted this fix prior. How To Reduce Tweeter Volume - Everything You Need To Know! Another avenue to consider is placing damping material on the woofer basket supports. The ringing may be your woofer basket/frame transmitting the resonant sound through your woofer cone. Not the cone itself, but the woofer frame.

I already have the LPAD to reduce tweeter, if I go further low then its way low
Your F R graph does not bare out what you describe subjectivity. My guess would be that either your original F R or impedance measurements are inaccurate or the tweeter is stuggling with a Xover frequency that is too low, particularly if you listen at a healthy volume. If you're happy the measurements are accurate I suggest raising the Xover frequency, otherwise I would remeasure then reassess.
Very unlikely unless they have both been over driven. I've heard tweeters after overdriving and they sound EXTREMELY metallic where the voice coil has separated from the dome and both vibrate loosely. Think of two hard surfaces vibrating against each other at high frequency for an idea of the sound.
In that case they are almost meaningless as they will not have taken account of the baffle step effect on your baffle. This is a big issue! You will therefore need to adjust tweeter level by ear and ignore the graph unless you can measure the actual FR and impedance of the drivers mounted on your baffle, then design the Xover using those.
