Enclosure suggestion
The EBP of 131 suggests a bass-reflex enclosure. EBP = fs / Qes = 38 / 0.29
Sealed (Qtc 0.707)
- Enclosure volume Vb
- 20.6 l
- System resonance Fc
- 96 Hz
- Cut-off frequency F3
- 96 Hz
Bass reflex (QB3 after Small)recommended
- Enclosure volume Vb
- 33.3 l
- Tuning frequency Fb
- 55 Hz
- Cut-off frequency F3
- 65 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.
