Ive built a ported sub box for my vibe 12in subs of my head.
When i crank it up it sounds nice & deep but when i crank it up real loud & put my head nr da ports, im getting port noise.
my port is 4in & i have it going very deep into the box but not touching da bottom obviously.
Also, its quite close to the wall of the box.
Can u guys gi mi some help as to why u think im getting this please, thanks.
By da way, i is from rainy old England, ruff London sides..
