what is an spl port?

i dunno thats y i am asking.

i'm only able to muster out a 140.8 with what i have, i think i should be a fair bit louder.

2 10L7s on 1000 watts a piece ported.

Typically an SPL port will be larger & shorter than a regular port.

Larger to let more air through, shorter for higher tuning. [img]graemlins/thumb.gif[/img]

ok so how do i go about desiging one?

just dont fire up in the trunk

Well for a daily driving port you will want to tune it fairly low, like 35hz-38hz. Get a program like WinISD and it will help you design a box.

For an spl port, there really is no magic answer. The general rule of thumb is "make it big and test" [img]graemlins/thumb.gif[/img]

sometimes a really tiny ox with a big long port helps too [img]smile.gif[/img]
depends on the vehicle that u are using...WinISD is cool and FREE!

win SD sucks big ass for me, i hate that program.

Hrm... that's funny... I thought you did all of your "big ass sucking" on your own?? [img]graemlins/deal4u.gif[/img]

win sd does most of it now, and its pretty good at it

From another forum
How to properly design a vented enclosure using WinISD

ok that has nothing to do with spl. and that is what he is asking, what works for spl.

But with Winisd he can calculate the port length for a tuning frequency, and it has different graphs you can compare one to the other..

As Quoted by JordyO "Typically an SPL port will be larger & shorter than a regular port. Larger to let more air through, shorter for higher tuning." -- Choose a higher tunning frequency and a bigger port size and it will give you the length..

u know im fing retarded. this whole time i was replying to the wrong post.
