Infiniti Kappa Perfect VQ 12"
fs 22.19hz
I have used 3/4 MDF for 1.32 cft sealed. so for that reason i didn't used the Mid Q or Low Q insert. .07cft is the sub displacement so therefore the actual inner area for sub to perform is exactly 1.25 cft.
F3= 35 hz
& Fmax = 50hz
Its is because i wanted some lower end extension. otherwise i would have used the Mid Q for most flatest response
