Open baffle woofer

Dear all.
I am searching the best open baffle woofer with alnico.
It has to be fast. The Lii Audio W15 is to slow.
What is the best JBL woofer for open baffle? Maybe the K151?
Or do you know one another woofer? Maybe Gauss, Celestion, Tesla or Lomo Kinap?
I listen often Electronic Music..
I am thankful for every recommendation

regards Daniel
 
I suggest to read this paper: https://adireaudio.com/wp-content/uploads/2018/12/Adire-Audio-Woofer-Speed-by-Dan-Wiggins.pdf
Assuming you are going to use a crossover or equalizer to shape the frequency response, all woofers are equally fast.

A second point: measure the systems frequency response at your listening position. Room modes will screw it up and make the sound boomy and 'slow'. If you equalize the bass range to be flat at the listening position, the sound will be 'faster'.

Thank you. To look for the induction "Le" i dont know know before.
What is about the "qts"?
People say 0,6 - 0,7 is good but is this really important? My Baffle size will be 70cm wide and has 30cm wings.
