Kicker L7

[tj1320 10+ year member]

I recently bought a Kicker S12L7 and I was planning on building a pretty big sealed box for it that is 3-5 cu. ft. I was flipping through the owner's manual last night and it mentioned that the maximum sealed enclosure space for the 12" L7 is 2 cu. ft. and NOT to exceed this amount of space.

This sounds strange to me because I remember going to an audio shop one day and seeing a truck with 6 10s hit like 150. Then I noticed one of the employees with a hatchback Ford Escort hit almost 150 with 2 12 Kicker Comps in a HUGE sealed box that filled up his hatch area. That box had to be at least 7-8 cu. ft. I assume his system was that loud because of the extra space in the box.

So why does Kicker recommend no more than 2 cu. ft. per sub?

You obviously have the room for a ported box if you have room for 3-5cubes sealed. I would say you would be better off using that space for a ported box. I had mine in 2.15 tuned to 32 hz and it was ok, but needed a bigger box for sure...I think somewhere around 2.5 @ 34-36 would be nice. (although I never tried it)

Btw, how much power are you planing on running?

I'm planning on running a JBL GTO1201.1 amp with the gain turned down some, of course.

The main reason I want to run a sealed enclosure is because of SQ. I hate distortion with a passion.

If SQ is your main concern, you might want to rethink your sub choice. I've read that L7's can have great SQ, but I think there are other drivers that will work better for your application.

i have mine in a 2.5 ported tuned at 35Hz. id say go with that but tune a bit higher, such as 38Hz. thats what the kicker tech told me. its a street beater sub. i really like mine, id buy another but SQ wasnt what i was shooting for. id say go sealed. 2 - 2.5 cubes.

If SQ is ur preference thn y in da world would you get an L7 I have 2 10" L7s and SQ is not in the Picture the only way 2 go with that sub is ported buddy... if u want SQ look into the Fi Q very nice sub or if you want loud a decent SQ mabey get an Alpine Type R...
