Greets!

Please post your calculator input, results.

Well, a driver has a box loading BW between its upper, lower mass corners with Fs its mean, so........

Fhm = 2*Fs/Qts'

Flc = Fs*Qts'/2

Qts' = Qts + any added series resistance [Rs]: HiFi Loudspeaker Design

Figure at least a 1/2 ohm for wiring.

Used this math to calculate the box alignment: Margolis-Small's HP 67/97 & 41C calculator program: AES E-Library » Personal Calculator Programs for Approximate Vented-Box and Closed-Box Loudspeaker System Design

Vb = 20*Vas*Qts'^3.3

Fb = 0.42*Fs*Qts'^-0.96

Convert this info into a MLTL alignment, ideally with the driver centered at whatever ear height and with such a low tuning figure it's only good for ~ a watt below ~100 Hz based on a 2 mm Xmax.
