Enclosure suggestion

The EBP of 154 suggests a bass-reflex enclosure. EBP = fs / Qes = 54 / 0.35

Sealed (Qtc 0.707)

Enclosure volume Vb
13.8 l
System resonance Fc
112 Hz
Cut-off frequency F3
112 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
26.2 l
Tuning frequency Fb
64 Hz
Cut-off frequency F3
69 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.
