those are out side mesaurements correct?

wood thickness?

check u're pm's

its for 1 kicker 15" l7 yes external

 

[jackson12375 10+ year member]

should i go for 33hz or 35hz for more ground pounding?

lower is better for distance..meaning the "walkers" at the bus stops will hear you from farther..heh

All though lower frequencies travel further, a higher intensity (in terms of decibels) are achieved tuning the box higher.

Just an FYI.

No offense, but might want to throw up the numbers, just in case.

or add more subs...

looks to be about 7.5cuft without port or sub displacement. Need port area to make any real determinations.

sqin = length

70 = 16.2

80 = 20.3"

90 = 25.8"

100 = 36"

110 = 839"

(all including .5" mdf as port walls ex:100=2.5cuft displacment)

longer = lower tuning from listed. All at ~35hz

Different bracing (less material) will result in a lower tuning with the same length

I cant give very accurate numbers until you give me port dimensions and how it will be built (such as using the wall of the box as part of the port)

so what is going to be the Port H=?

W=?

L=?
