Enclosure suggestion

The EBP of 100 is in the intermediate range — either works; sealed plays tighter, bass reflex deeper and louder. EBP = fs / Qes = 33 / 0.33

Sealed (Qtc 0.707)

Cut-off frequency F3

Bass reflex (QB3 after Small)

Enclosure volume Vb

Tuning frequency Fb

Cut-off frequency F3
46 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.
