Enclosure suggestion

The EBP of 68 is in the intermediate range — either works; sealed plays tighter, bass reflex deeper and louder. EBP = fs / Qes = 27 / 0.4

Sealed (Qtc 0.707)

Bass reflex (QB3 after Small)

Enclosure volume Vb

Tuning frequency Fb

Cut-off frequency F3

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.
