Enclosure suggestion

The EBP of 141 suggests a bass-reflex enclosure. EBP = fs / Qes = 89 / 0.63

Sealed (Qtc 0.707)

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

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
30.0 l
Tuning frequency Fb
65 Hz
Cut-off frequency F3
57 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.
