bracing, fiberglass
Bracing... as in inside the box?

I have 2 JL w6's in a upside down ported enclosure port facing front.
that being said, the back of my box (non ported side) is rattling like a mofo below ~ 35 hz and below. How could i make it stronger, literally its screwed in a billion times its the middle of the back if i have the volume at low enough levels to where it does it i can ALMOST stop it with my hands, but i have no idea on how to make the wood stronger.
I thought about doubling it up but then i would just have two pieces of wood clackin against eachother...

Okay all over youtube i see people posting video's of there subs playing " I wanna love you" But the musics slowed. ( me being a absolute noob) If i slowed the song by my self or someone else did it for me wouldnt it get choppy how video's slow down on youtube? is there someone who could possibly teach me how .. and clipping. would there be major clipping after?

intresting thing tho is I had every ticket in my Jeep......Had 22"s on it. And spinners when they were still cool. lol (<I know dont tell me)
Best part is my beamer was louder and never got a single ticket.....for stereo related infractions anyways.
Its the soft tops, (if you had one) its like me leaving my window down. it sounds just as clear lol
-
I been bumping it for few months now and no problem .
I even drive by police station few times a week with music on sometimes.
I'm in Hamilton
Your pretty close to me. i live like 2 mins from elmer, and 10 mins from glassboro. its just kids at school being pricks since i dropped out haha they jelly
-
it will vary by town and municipality.
Could be different in NJ but here in NC its basically anyhting the cop can hear and if he feels like pulling you for it. I've had at least 5 tickets for it. 1 of which i had to go to court for. Crazy. Each ticket was $50 and the court one costed me in the $150 area.
Basically its like speeding, everyone (with a system) does it just try not to get caught.
Thanks n8
Rogue- Yeah ive got some old friends that i dont go to school with anymore being pain's in my rear end complaining when i go past there house they hear it for about 10 seconds, its not even a loud system just 2 w6's in a ported box. i guess its the softtop and the quite country!

Does anyone know the laws about loud music for NJ?

I see more and more misunderstandings about this subject.
Power HANDLING has just about nothing to do with how loud a woofer will play. Just how much power the sub will handle.
You can have a 10,000w rms woofer get just as loud on 100w as a 100w rms woofer. It's other factors in the woofer construction that determine its loudness.
And no, an 18 is not "Stiffer" than 12s. that is not a factor.
What it can come down to is the materials used and construction of the woofers. If all that is equal, a single 18 has about 250 sq inches of cone area
Two 12s have about 225 sq inches of cone area.
This means that the single 18 does have a greater Potential to be louder.
Another factor is that the greater power handling of the single 18 would mean that it will run more reliable and more efficiently due to staying well below it's thermal limit. However power being spread over multiple coils can also exhibit that effect.
Ultimately what it will come down to is the enclosure, a pair of 12s may work better in smaller trunk cars due to the enclosure techniques and the single 18 may work better in a larger hatchback for the same reason.
It's up to you and your enclosure design and building capabilities.
BUT!!!! a 4000 watt rms 18 sure the hell is much stiffer then a 600 watt 12 so giving the 4000 rms sub 1200 watts will be under powered and not move as much as the 12's with the same power.. you could run a bigger more effecinet box but that will only go so far in all my testing the subs getting there rms was allways louder and less peaky then the under powered sub
Just because a woofer can handle more power, does not meant that it will be stiffer. In fact, it shouldnt be. Some are, yes, but it depends on the woofer. The stiffness of some woofers is a side effect of the adding lateral control to the suspension.
You can say.
But you are saying that your woofers get smelly from 600w rms each?
I think you may have another issue at hand and that distortion.
Have you attempted to adjust gains and level settings with an O-scope or any clipping meter? Or the help of a knowledgeable gain setter?
Proper tuning can be your solution.
Also, if you are looking to upgrade, a higher end single 18 does have the potential to perform better. I would suggest an efficient woofer but also set your gains right or you may have the same issue.
The sub im looking at is an SMD 18
The gains were set buy an authorized JL audio dealer. as for clipping the headunit never goes above 24/35 and the ipod is on 80/100 i check all my songs on audacity for clipping as well. if i see one clipped note, it doesn't play ever. to much money in this system with little to no bang
just cause a dealer set your gains in no way means he knows what hes doing he MIGHT but he is a sales person thats it
for the smd i would look at a differnt sub that thing is a beast i dont think your ready for
Dont act like you never had your first time at anything. I am on this forum for a reason.
dude i was being serious with you its a lot of money and you really should know what your doing with that sub did you walk befor you could crawl? if you cant understand why your subs smell YET i say yet cause you can learn then really your not ready but just cause i say that dont mean shit go for it if you really want it
ill put it to this way i got into rc helicopters had a few ok ones then jumped up to a super big boy crazy one i keep destroying because i thought i was ready i was not so now i keep repairing it cause i dunno what i am doing and i crash it i now put it on the self and now i am getting a better more simple learning heli befor i try and fly the expensive bad ass one
ive speny more money between my two w6's then this one SMD. This is a downgrade in cost, but upgrade in power. I will learn as you have learned with your helicopter. But i actually have the money to keep using the bad ass smd.
You spent too much
thanks for point out the obvious
. what would i ever do with out the pointless statement? -

That sub is a beast that can handle a ton of heat. But has been shown to shine at power levels above 3000w.
If your gains are correct, the enclosure and choice of program material can be another issue if you play songs below the tuning frequency.
If all that is good, maybe you do just need (and I feel you want) to upgrade the woofers.
The easiest upgrade is just a beefier pair of 12s.
But
going to a single beefy 18 does give you the chance to upgrade to higher power in the near future.
Exactly and the bling bling factor
i think the tuning frequency i am playing them at is actually whats making it smell i do notice it happens at around 20-25 hz and then stops smelling terrible when i play 30-50 hz songs and after awhile it goes away. Then if i play the 30-50 hz songs its fine. put on the 20 hz songs it smells i didnt even know that was possible. ( So leads me to the question is that bad) im gonna assume thats its damage some voice coils? -

I think by "Air movement" The above posters really mean displacement.
At 1200w total, how much air can 225 sq inches of cone area displace at its given excursion at that power Vs. 250 sq inches of cone area at it's excursion at that power level.
Depends on what woofers you are talking about.
Unforfently i am not allowed to post about any specific brand because it will bring rager's ill get banned ill PM you the brand i am looking at and have atm.
You can post your brand of subs if you want, If you want proper help from posters, you have to. I am a mod, I will allow it.
My brand of subs are 2 JL Audio 12w6's on a 1200.1 JL HD amp.
if you want the brand of 18 im looking at tell me its allowed and ill post it.

Ive never owned an 18 and from the youtube video's i watch i always see people that can never bottem out a 18 with there hand ... and in some cases can barley move them! And thermal limit is my problem right now since my subs are seriously stinking but not getting hot? i dont know whats wrong but this is why im thinking bigger may be better.
-
now if they are the same subs and rms differnt sizes
like a aa mayhem 12 rated for 2500 watts getting 2500 vs a mayhem 18 2500 rms getting 2500 rms the 18 should be louder everytime cause of cone area but again this is all box dependent
Now it all makes sense for you "Air movement" example. Lets try not to make this a vs thread since if i have one more vs thread i get banned.haha. but i totally understand now. thanks for your help
-
in threoy the 12's will be louder but it all depends on the install
the 1 18 has a little more cone area but will be under powered and will not perform the best that it can
the 12's will be pushed to there optimal performance for the rms and will move more and hit close to there xmax where the 18 will be crusin
All of the statements above are true but i didnt want to say to much about the box and stuff because itll make people rage. The last statement in this post, the 18 would be cruising but wouldnt it still be the same loudness lol i guess its a hard topic to explain to a noob
-
I have been wondering;
2 subs ... Lets say 12's for example 600 RMS Each
-with-
1200 watts.
1 sub ... lets say an 18 as another example 4,000 RMS
-with-
1200 watts.
Would the 12's that take the amp to full potential be the same "loudness" as the 1 18?
- to keep it easy lets just say they are in same condition's blah blah blah I am just wondering would it be the same power? I feel like it would but then again im always wrong
My theory: If the two subs are maxing out at 600 RMS each on a 1200 watt amp they will be making "x" amount of loudness. If the 18 is taking the SAME 1200 watts i would think they would sound the same due to BOTH are able to take up all 1200 Watts but (this is where i get stumped) Would the amount of cone space or amount of sub woofers take the loudness down? Completely stumped. I am sure for all you smart audio guys out there this is a no brainier haha.
-
Maybe you're smelling the inside if your box.
The box does have a leak where air goes through ( to the magent of the subs) since there inverted and the cones shoot down into the port i might be smelling that?
-
They never get warm? i have the headunit at 24/35 and my ipod 80% flat EQ. I dont bass out like most people do. Both of the subs make a scratching noise when i push them past half way. i dont know if that normal? Both subs are very easy to push it also
-
The JL's should smell like perfume when they get burned up, if not please go back to the dealer.
(it's probably because the subs are still brand new and the glue still has to cure fully )
Its mostly when there hitting below 30hz. they push alotttt of air out and they smell werid lol. just making sure (as the subs are only a week and a half old)
-
I have two JL audio w6 12's in a ported box with both subs facing down toward port, when i put my face up to the port i can smell a faint smell from the subs? It does not smell like the memphis that i burned up but it is making me worry!
-
Thank you both it is e40 - My shit bang.. I thought it was Blegit so i kept looking through all there songs and none of them had the same beat

E-40 at 43
Thats the song before the song im talking about. sorry i should have been more descriptive :/ do you know that song? hehe
. what would i ever do with out the pointless statement?
i think the tuning frequency i am playing them at is actually whats making it smell i do notice it happens at around 20-25 hz and then stops smelling terrible when i play 30-50 hz songs and after awhile it goes away.
