Port tuning Question.

[PioneerSPL1990 10+ year member]

Im building a box for a 21" Incriminator Audio Death penalty 21" and have dimensions i have to stay within.

dimensions are 34Wx 15hx 29d. after .75" wood displacment that leaves 6.982 cubes of space to work with.

now the tough part i want the tuning to be 28 Hz, but i dont want the port to be 4.5x13.25x25 i want a port lenth that doesnt L. and a larger port opening so i dont have a super high velocity or high port restriction.

i dont have specs on the sub and ill be powering it with a AP3500D

dont have them and they r not on there site, i called but they are at the CES show in vegas till tommorow, and resume work weds.

it is a bit small but it is the biggest i can stuff in my car. if worst comes to worse ill have to go 5x13.25.25 that gives me 28.4 but the velocity should make the port whistle lol

Why not have an l port? My l port with my dp works fine! Loud and low....also not one peep of port noise at all!

looking for spl, with an L its more air resistance resistance, but as i have it i don't think im going to get the output im looking for.
