Re: few questions for the experienced
Forth orders are really only good if you have awesome midbass or are willing to give up a little low bass. Usually they only cover about an octave where as a good ported box can reach up to about 3 octaves
1 octave 20-40hz
2 octave 40-80hz
in some cases ported boxes can reach 3 octaves
20-40, 40-80, 80-160
but really we only need 30hz-80hz in most applications
depending on vehicles low tuning can result in a flat respone usually smaller cars
In suvs u can tune higher and still reach low due to the lower cabin gain.
my versa for example gain 3-5db 62-75hz but my box starts dropping at 58hz.so where the box drops off the car picks up resulting in a much flatter response that if I was tuned higher.
im tuned to 32hz now I want to tune to 33hz and see if I can close the gap inbetween the box fall the the cabin gain
