I don't think Crafft used a standard 17W75, a that driver used to be built exclusively for a sealed cabinet, so you might want to double check the TS parameters. Being vented, it was likely a version of a stronger motor called XL or LQ. I haven't got original Crafft filter but it was probably a version of a crossover implemented very often back then. Shallow filter slopes of first order with additional impedance flattening circuits and a lattice delay network for the tweeter. Search for the Dynaudio Aries schematic and modify to suit the drivers.
Dear Lojzek,
Thanks for your kindly help.
My 17W75 driver label 17W75 audience(from dyn audience 5 speaker).
An externally hosted image should be here but it was not working when we last tested it.

- I made 2cm thickness MDF cabinet with a volume of 15 liters as a technical document of dynaudio crafft. Add 1.5 cm fabric (two sides, above, below inside the cabinet), made 2 holes (2.7cm diameter, 12 cm length)
However:
- Too much and heavy bass
- The mid/mid low is low so the vocalist is not loud and is drowned in bass and treble
- Tweet is ok.
(bass cross with 1.2mh Mundort BN120 zero ohm inductor, tweeter cross with 0.47 solen air inductor, solen/audiocap capacitor, taiwan resistors)
Please help me made it better, many thanks!

If it were me, I'd use a larger cabinet. An opportunity maybe to add large roundover framing with cardboard tubing, many ways it could be done. Some would alter the crossover instead. Perhaps a combination.
