Need help designin a box for a Kicker 0512L72

[vetkilr]

I was lookin for specifics to help someone,but all Kicker gives is a sealed and ported specs and not any general info in thier Manual.

On thier site it says the 06 which is rated the same as my 05:
Resonance frequency[fs],HZ = 34.0

Total Q-factor[qts] = .513

Equivalent volume[vas],ft3(l) = 2.2(62.5)

My trunk can fit around a 32X13X13 give or take a inch.

Ive had Bandpass in the past and love it........I looking for the most Boom for the Space I have.........I was wondering if 2 speakers in a sealed box would hit harder or one with the correctly designed box would hit harder.

I listen to technoBass notes/Rap and alot of others includin country..hehehe

But I like to have really low bass hittin capibility without losin alot of clarity for my country days.






Thankx for all the help guys.

Most boom? Then go for a ported or a bandpass enclosure...

Do you have the Xmax?

Xmas=

.52in/13mm


Thankx

I think your box is too small to go with bandpass...

I'd go with a ported enclosure of 13x13x32 tuned with a single 4" diameter full length precision port.

Whats a 4" full length precision port??

[vetkilr]

I going to make a 2 piece box and make it 6th order!!

2 cubes each side........one to 35hz the other to 78hz.

Its just killin the ported box down low and up top by 3-5dbs and has a nice slope.....

What do you think???

Any programs out there to design or draw your box out good as Ill need to put it together somewhat in my trunk

[simon5]

13x13x32 = 11.5x11.5x30.5 assuming you're using 0.75" walls.

That's 2.3 cu.ft internal net. Now remove driver volume, braces and port volume, you're probably at 2 cu.ft.

There's no way you're gonna fit 4 cubes in that space.

To design a box, you could use a CAD program...

A full length precision port is this :

[vetkilr]

Are there any free Cad Programs out???

I was thinkin about makin a 2 piece box and semi buildin it in the trunk

Looks like it is best just to build a ported box at around 40-44hz with a subsonic filter on it for 30-35hz with a 24db cutoff to avoid over excursion under that ........

What you think??

[simon5]

Bah, I was thinking tuning it with a precision port like I've showed you. That would tune it around 27 Hz then add a subsonic at 25 Hz.

[vetkilr]

doin that I have a major cone excursion at 47-67hz at 750watts or more.

The rms is 750........I was tryin to get around 900 safely without over excursion???
