Enclosure suggestion

The EBP of 116 suggests a bass-reflex enclosure. EBP = fs / Qes = 43 / 0.37

Sealed (Qtc 0.707)

Enclosure volume Vb
72.4 l
System resonance Fc
87 Hz
Cut-off frequency F3
87 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
139.6 l
Tuning frequency Fb
50 Hz
Cut-off frequency F3
53 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.
