Enclosure suggestion

The EBP of 107 suggests a bass-reflex enclosure. EBP = fs / Qes = 44 / 0.41

Sealed (Qtc 0.707)

Enclosure volume Vb
35.0 l
System resonance Fc
80 Hz
Cut-off frequency F3
80 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
71.6 l
Tuning frequency Fb
46 Hz
Cut-off frequency F3
46 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.
