Enclosure suggestion

The EBP of 182 suggests a bass-reflex enclosure. EBP = fs / Qes = 51 / 0.28

Sealed (Qtc 0.707)

Enclosure volume Vb
8.5 l
System resonance Fc
134 Hz
Cut-off frequency F3
134 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
13.3 l
Tuning frequency Fb
77 Hz
Cut-off frequency F3
91 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.
