Enclosure suggestion

The EBP of 150 suggests a bass-reflex enclosure. EBP = fs / Qes = 42 / 0.28

Sealed (Qtc 0.707)

Enclosure volume Vb
22.4 l
System resonance Fc
110 Hz
Cut-off frequency F3
110 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
34.8 l
Tuning frequency Fb
63 Hz
Cut-off frequency F3
75 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.
