Cuz hifonics is bad. 12-16 of port area per cubic foot is what they say

yes i know.. but is there a limit to the 12-16 inches per cube ft rule

so far flared ports is the only flared ports gets away with cheating that rule

its a rule of thumb to stay above to not get port noise but you should get as much as you can always.

wrong

if you give 16 sq inches to a hifi its going to fall on its face, not enough linearity or motor force to handle that much port are.

Yep, keep port area lower to accomodate for a weaker woofer. ~25in^2 for a 12" Hifi is plety. No need for a 2-2.5ft^3 box with 32-40in^2 of port, because like you said, it'll fall on it's face without enough air spring in the box.

So im not wrong. IT lacks motor force and linearity, which tells me its a sucky sub. so im right

 

[lilboom 10+ year member]

so port area is also subwoofer dependant

I like rockford fosgate is ok and they also say 1 3inch diameter port for 1.75cube p1 12 also a low power woofer

 

[Cruzer 10+ year member]

imo not if u buy a quality sub and not a $15 sub from amazon

 

[Cruzer 10+ year member]

jl says same, 3 inch port is fine. i just gave the 12-16 for slot port, but i also trying to point out hifonics cheap subs. ive never done aero, want to tho, it looks a lot better imo

While we are on the discussion of port size and win-isd, what relevance does the port match serve? Is this related to port noise? No one ever explained all the parts of win-isd to me, I taught myself, am still learning and am eager to learn all that I can.

 

[Cruzer 10+ year member]

what do u mean "port match", is that in winsd? i dont see it.
