when designing an enclosure, how does driver displacement affect the tunning? for instance, if you calculate the enclosure volume and tunning before displacement to what you want. when you add the driver, obviously the displacement makes the enclosure volume smaller but what does it do to the tunned frequency? increase? decrease?
here's an example with measurements before displacement...
W = 18.25
H = 14.75
D = 23
port width = 2"
port length = 6"
2.29^3 @ 30.1
driver displacement is .15cu so the volume after adding the driver would be 2.14^3, correct? tunning?
