Enclosure suggestion

The EBP of 135 suggests a bass-reflex enclosure. EBP = fs / Qes = 42 / 0.31

Sealed (Qtc 0.707)

Enclosure volume Vb
18.4 l
System resonance Fc
102 Hz
Cut-off frequency F3
102 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
30.6 l
Tuning frequency Fb
59 Hz
Cut-off frequency F3
68 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.
