I'm looking to build a vented enclosure for my JL 13w1v2..

JL Reccomends a 2.625cu ft vented box tuned to 26Hz. about 23" x 17" x 18" is what they reccomend.. i belive 18" may even be too deep with the amp on the back seat, my box is 12" deep right now and at 16" high it hits on something in the back. so i if i could squeeze it to like 28x15x15... could i still get the tuning? would i just make my port a little wider? btw, i belive all this is before port displacement not sure.. driver displacement is only like .05 cuft, so not a hgue problem there.

any ideas :Pi really want to hear this sub in a vented box, maybe even more of a spl box.

if you want an spl box you want to tune higher. if it was me i would tune that sucker to 22hz so i could really impress people with low bass tones

2.625 at 22hz??? you will burn it up i gurantee it. depending on how much power your giving it of course

i think it will handle it. its FS is 20.9. actually i think it would really like that box.

how much power is he giving it? hope its clean power clipping the amp at that low is deadly.

rms is 200 on the sub so he shouldnt have any problem clipping it. i think he has a jl 250/1

O Ok Lol Here I Go Again Thinking Huge Power ... I Think I Have Watts Syndrom Damn Spl Competitions

22 Hz?

Thats crazy low...

Actually stupid low...

Seriously if you want ported stay around 32-34 Hz for daily. Maybe 40-48Hz if your going to compete...

Tuning that low will give you a gain, but the gain wont be very audible... So what good is the gain if you cant hear it?

actually i have a JL e1200 and from what i know JL certainly doesn't make shitty amps, so its probably clean power :P, so its seeing about 120watts. 22hz sounds good.. its all just a matter of designing the box to actually fit comfortably in my car.

22 Hz Is Crazy Crazy Low Be Very Careful
