Enclosure suggestion

The EBP of 73 is in the intermediate range — either works; sealed plays tighter, bass reflex deeper and louder. EBP = fs / Qes = 35 / 0.48

Sealed (Qtc 0.707)

Bass reflex (QB3 after Small)

Enclosure volume Vb

Tuning frequency Fb
29 Hz
Cut-off frequency F3
27 Hz

Vb is the required net internal volume, Fb the tuning frequency of the reflex port and F3 the frequency at which the level has dropped by 3 dB. Calculated approximation after Small. A starting point for simulation, not a finished build plan.
