Enclosure suggestion

The EBP of 103 suggests a bass-reflex enclosure. EBP = fs / Qes = 40 / 0.39

Sealed (Qtc 0.707)

Enclosure volume Vb
68.6 l
System resonance Fc
79 Hz
Cut-off frequency F3
79 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
134.6 l
Tuning frequency Fb
45 Hz
Cut-off frequency F3
47 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.
