Enclosure suggestion

The EBP of 111 suggests a bass-reflex enclosure. EBP = fs / Qes = 39 / 0.35

Sealed (Qtc 0.707)

Enclosure volume Vb
54.9 l
System resonance Fc
86 Hz
Cut-off frequency F3
86 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
99.2 l
Tuning frequency Fb
49 Hz
Cut-off frequency F3
55 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.
