need help on a box for l7 15

[kidd666]

I need some help designing a box for my truck. i just got a 15" l7 and i've never made a box before. i know that i like ported over sealed and i know that im going to want it tuned at around 30hz. ill run out and get some measurements of space i have to work with. i have a 94 chevy k1500 ext cab. any help would be greatly appriciated

your max dimensions you can use would be a good start....I am sure somebody here can help put something together for you, guys are quite helpful with box advice

My friend has an L7 15 in a sealed 4 cuft box and it plays 26-35 hz really good and its on 200 watts less than my Rockford T2 15 in a ported box. My point being l7s sound good in sealed boxes and you havent built a box before so a sealed box for that sub might not be a bad idea

how do you know that you want it tuned that low? you are aware that it's completely possible to play low with a higher tuning, right?

also, l7s hate sealed boxes.

i got it in a seled box and i didnt really like the sound. i know its just a factory box and its probably not big enough for it anyways.

[kidd666]

i did not know that. ive always just thought that u need it tuned low to hit the low

ported is recommended 3-6cubes....I would do 3cubes sub forward, port to the side and tune around 33-35hz personally, depending on how much power your running to it

[Guest]

3 cubes ported? are you insane? more like 4.5 to 5 or so. they like big boxes.

also, no. it's a misconception. you tune that low and you're going to lose high end output

ok so i have 24" from the back of the cab to my seat, 60" side to side, and 48" top to bottom

Ive built plenty of boxes for kickers specifically the cvx, l7, and cvr models.

They are perfectly fine for a 15 to run them in 3.5 cubes net. At this volume you can tune a little higher to say 36hz and still hit low to 30hz no problem.

If you decide to go a little more on the volume like say 4-4.5 cubes net then tune it to 32hz.

It really depends on your music preferences, if you like a varirty of music from rock techno to rap then do 3.5-4 net tuned to 34-36hz.
