Help choosing Purifi midrange

Hello everyone.

I want to replace my midrange speaker. Now I have an audiotechnology 18H52 17 06 cut at 300 and 3000 hz with a slope of 48db. The cut is digital with Dephonica software.

My candidates are the Purifi, but I don't know which model to choose.
PTT4.0M08-NFC-01
PTT4.0M08-NAC-03
PTT5.25X08-NFA-01
PTT6.5M08-NAA-08
PTT6.5M08-NFA-01

The upper cut must be a minimum of 2500 since I have a Raal 70-10. The woofer is a TAD1603 and can be cut higher than 300hz if necessary.

The impedance must be 8 Ohm.

The aspect that I value most is the detail.

I'm open to other speakers in that price range.

Thank you so much.
Greetings
