Enclosure suggestion

The EBP of 108 suggests a bass-reflex enclosure. EBP = fs / Qes = 39 / 0.36

Sealed (Qtc 0.707)

Enclosure volume Vb
17.8 l
System resonance Fc
131 Hz
Cut-off frequency F3
131 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
21.3 l
Tuning frequency Fb
76 Hz
Cut-off frequency F3
101 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.
