Enclosure suggestion

The EBP of 123 suggests a bass-reflex enclosure. EBP = fs / Qes = 38 / 0.31

Sealed (Qtc 0.707)

Enclosure volume Vb
52.3 l
System resonance Fc
90 Hz
Cut-off frequency F3
90 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
89.6 l
Tuning frequency Fb
51 Hz
Cut-off frequency F3
58 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.
