snail shell enclosure for level 5's


Recommended Posts

For those wondering wtf a snail shell enclosure is:

12snailshell.jpg is supposedly something like it.

Heres a thread about them from 'way back when' from DIYaudio. Alot of the original people from this forum and A LOT of STUPID LOUD people were on their forums a few years ago.

what size driver is that designed for? What is height? looks interesting!

That box design looks really wierd, and complicated to determine. I get that from the fact that each port piece has a different width, really weird. Where does the sub(s) go?

I'll admit, half way through sanding that fiberglass in the rain and cold while I was all itchy I was definitely starting to question why i was doing this haha

did some digging and found it -- sub goes to the right, almost like a normal ported box. Height is 15" (if it's same one I found, designed for RE XXX 12") Not sure on tuning freq.....would have to be pretty low, with that length of port.

That is def an interesting SS designs, must have been specifically for that sub (the way it should be) if I can find the infor I remember getting the design info of of powered4sound for free before it became nolteaudio.com and it was mor like a tapered horn for the crystal audio subs. I built a basic one for a kicker comp a while back and to me came out amazing. Should be interesting with real powered subs =p

I don't think anyone said they haven't heard of Nick doing anything good lately, Just that he hasn't been seen around lately. As I am sure others who know him will agree, He is very talented in his box designs.

Designing, building, and shipping boxes. Yahoo IM - kingsuv00If the listening level is too loud, please inform the driver, so he can promptly pull over, and let you out.

not many cars can get me to pluggin my ears but this one.......damn. I mean the first minute is ok but that thing just really starts digging deeper and deeper in your earhole till you cant stand it no more. Seems like it does it with relative ease....16 12's on 8 amps.........gotta love it. :)

Correct, it was allegedly for an RE xxx 12" @ 15" in height. I have no idea about tuning because this is nothing like a regular ported box; it is, from what I understand, something to do with 1/4 wave(which im not sure how that is build to the woofer itself, as I understood it as being install dependant). 1/4 wave was a huge thing and surely still is in the SPL world, and less used in the daily world, but several VERY loud people still use it/build around it, damn over-achievers.

The 1/4 Wave or ABCD Theory was a big fad in SPL for quite some time, especially in walled subwoofer systems. With this article I hope to explain what it is, how to calculate it and you can draw your own conclussion from there.

In a wall if the port opening is located ¼ of the tuned frequency’s wave length away from the windshield/microphone you gain constructive interference. This occurs because the originating wave (from the port) and the reflected wave (from the windshield) will "mix" with each other at the peaks & troughs of their wave form. This effectively boosts the amplitude (hence volume) of the wave. Thats the theory.

Just a short version of it. ^^

i did speak with john nolte last night, this guy is amazing!!! he knows is stuff, but he said he retired from the car audio world and he is now focused on high end speaker enclosures for home theater, he will be helping me out on my build but darn it i really wanted to slap some level 5's in a dual snail port enclosure.......... i myself do not have the right tools to build a good box that is high spl worthy, let alone i am fairly new to the car audio world and dont really know sheet from shineola....but i am soaking everything in!!!

THANKS FOR EVERYONES INPUT!! I VALUE IT ALL
