Enclosure suggestion

The EBP of 173 suggests a bass-reflex enclosure. EBP = fs / Qes = 45 / 0.26

Sealed (Qtc 0.707)

Enclosure volume Vb
12.6 l
System resonance Fc
127 Hz
Cut-off frequency F3
127 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
18.2 l
Tuning frequency Fb
73 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.
