Enclosure suggestion
The EBP of 146 suggests a bass-reflex enclosure. EBP = fs / Qes = 35 / 0.24
Sealed (Qtc 0.707)
- Enclosure volume Vb
- 31.7 l
- System resonance Fc
- 108 Hz
- Cut-off frequency F3
- 108 Hz
Bass reflex (QB3 after Small)recommended
- Enclosure volume Vb
- 42.0 l
- Tuning frequency Fb
- 62 Hz
- Cut-off frequency F3
- 79 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.
