Enclosure suggestion

The EBP of 159 suggests a bass-reflex enclosure. EBP = fs / Qes = 54 / 0.34

Sealed (Qtc 0.707)

Enclosure volume Vb
11.4 l
System resonance Fc
116 Hz
Cut-off frequency F3
116 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
21.1 l
Tuning frequency Fb
66 Hz
Cut-off frequency F3
72 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.
