Enclosure suggestion

The EBP of 203 suggests a bass-reflex enclosure. EBP = fs / Qes = 61 / 0.3

Sealed (Qtc 0.707)

Enclosure volume Vb
4.7 l
System resonance Fc
149 Hz
Cut-off frequency F3
149 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
7.7 l
Tuning frequency Fb
86 Hz
Cut-off frequency F3
99 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.
