Enclosure suggestion

The EBP of 103 suggests a bass-reflex enclosure. EBP = fs / Qes = 36 / 0.35

Sealed (Qtc 0.707)

Enclosure volume Vb
65.7 l
System resonance Fc
77 Hz
Cut-off frequency F3
77 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
121.6 l
Tuning frequency Fb
44 Hz
Cut-off frequency F3
48 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.
