My double JL sub box

[nis.k.a.]

Like I said, I tried it already. Doesn't sound as good as firing straight up. I got a bigger range of tone this way.

Nice set up man, props. For anyone else looking for good subs check these guys out

www.hsuresearch.com

they specalize in sub's and make one for automotive applications. Here are some specs

12" , 13mm Xmax, 16-100 Hz frequency response, 100 db, $109 each. Read up in their review section, great info...lame site

Dont forget the main thing about all this, the sound resonance also happens inside the box, wether be it ported or non ported, and when it is ported, the length and diameter are crutial and they determine the frequency responce. so its not the direction the subs fire in, but the volume of box and ports. Thats the whole point of making a custom sub box.

You to dawg. Keep the G safe and secure over the hollidays.

the thing about his set up is this...

he has his subs facing the rear deck... putting a lot of pressure on those deck speakers when the bass hits (my guess is that the cones on his deck speakers will last 4-6 months max if he uses those w6's correctly )

and so he has ports as well... the ports are facing the end of the car- this part is good- it will traval back- and bounce and give him some distance... and he'll feel the resonance more (the shaking feeling of the bass)

the reason why you need distance is because low frequency waves are really really long- i think a 20hz wave stretches something like 15-20 feet for one full wavelength... soo- the more distance- the more he'll feel the resonance frequencies in his car... as opposed to shaking everyone else's cars around him (which will still happen because we al know that the car isn't 20 feet long.)

so- distance is good. he gets it with his ports. his deck speakers will need replacing soon- but since he's got all this cash into it- he'll be ok with replacing them... or better yet- putting a set of components in the rear doors for rear passengers and creating a WONDERFUL soundstage for rear passengers as well as front passengers.... do this- then just keep open holes to your trunk and let the bass flow in.

NOW - THAT- WOULD BE A GOOD IDEA...

good points, well made.

in my past experiences with this setup i.e. subs facing upwards towards rearshelf speakers, ive never encountered any problem with damage to the deck speakers,Also, this is with lesser quality speakers aswell. Anyway, ive noted your points, i keep a look out for any signs of damage. I sometimes tend to run the system without the subs, so hopefully spot any distortion damaged speakers may give, Cheers

That's what I was trying to point out!

when i saw the box you made and the roof rack and everything else you made i had to go pee but it wasnt pee :alien2: anyway man you got speed turbo and going to bigger turbo and you have suspension and you got bodystyle and you got audio and you got every freakin thing there is
whats next? i always wonder what u got planned!
i guess when i get money for my creativity i hope tyo share them like you share yours.
keep up the good work

the crew here check this out you guys know a damn lot and audio is not my strong point but i need your help i would like to know if you can assist me in building a box like this picture i will post
i will drop the info that was included with it but basically i would like to know how to build a box not of wood but like this
thanks
casual


plexiglass box
or where can i see more boxes done like this
credit is due to hybridamp this is his box but i cant seem to get in contact with him
i would like to make this style boxes for trunk

its really nice JTL wish i had it in my car
