Enclosure suggestion

The EBP of 159 suggests a bass-reflex enclosure. EBP = fs / Qes = 35 / 0.22

Sealed (Qtc 0.707)

Enclosure volume Vb
16.6 l
System resonance Fc
118 Hz
Cut-off frequency F3
118 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
19.9 l
Tuning frequency Fb
68 Hz
Cut-off frequency F3
90 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.
