Enclosure suggestion

The EBP of 103 suggests a bass-reflex enclosure. EBP = fs / Qes = 31 / 0.3

Sealed (Qtc 0.707)

Enclosure volume Vb
37.8 l
System resonance Fc
76 Hz
Cut-off frequency F3
76 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
62.9 l
Tuning frequency Fb
43 Hz
Cut-off frequency F3
50 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.
