Enclosure suggestion

The EBP of 114 suggests a bass-reflex enclosure. EBP = fs / Qes = 32 / 0.28

Sealed (Qtc 0.707)

Enclosure volume Vb
39.1 l
System resonance Fc
84 Hz
Cut-off frequency F3
84 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
60.8 l
Tuning frequency Fb
48 Hz
Cut-off frequency F3
57 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.
