Enclosure suggestion

The EBP of 161 suggests a bass-reflex enclosure. EBP = fs / Qes = 53 / 0.33

Sealed (Qtc 0.707)

Enclosure volume Vb
5.9 l
System resonance Fc
121 Hz
Cut-off frequency F3
121 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
10.4 l
Tuning frequency Fb
69 Hz
Cut-off frequency F3
78 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.
