Enclosure suggestion

The EBP of 224 suggests a bass-reflex enclosure. EBP = fs / Qes = 65 / 0.29

Sealed (Qtc 0.707)

Enclosure volume Vb
2.6 l
System resonance Fc
170 Hz
Cut-off frequency F3
170 Hz

Bass reflex (QB3 after Small)recommended

Enclosure volume Vb
4.0 l
Tuning frequency Fb
98 Hz
Cut-off frequency F3
116 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.
