Enclosure suggestion
The EBP of 100 is in the intermediate range — either works; sealed plays tighter, bass reflex deeper and louder. EBP = fs / Qes = 35 / 0.35
Sealed (Qtc 0.707)
- Enclosure volume Vb
- 93.6 l
- System resonance Fc
- 75 Hz
- Cut-off frequency F3
- 75 Hz
Bass reflex (QB3 after Small)
- Enclosure volume Vb
- 173.2 l
- Tuning frequency Fb
- 43 Hz
- Cut-off frequency F3
- 47 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.
