Dayton Ultimax 18 or Stereo Integrity HT-18 v3

OK, so low inductance for subwoofer drivers is a good thing for SQL basically.
Well, yes and no as I noted, just depends on how wide a BW you want it to have, but primarily what matters is its Qtb defining its SQL with 0.5 being transient perfect, so in this case we want a driver with a < 0.5 Qts' with the lower it goes the wider its BW (Fhm = 2*Fs/Qts') and where its inductance/Le might come into play if the XO point is at/above this point.

(Qts'): (Qts) + any added series resistance (Rs)
