What ever happened to Snail Shell enclosures?

[Volenti 10+ year member]

Really good try, but still not quite a snail shell. Getting a little warmer.

It's all variations on the same theme, it's not my problem you have a narrow, rigid definition of what a "snailshell" is, something you haven't actually described BTW.

I've been thinking that too. But chances are the people who buy them don't really care if they differ from a TL or not, they're just concerned with how "hard it bumps" //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif


Is that a challenge?

I think they get loud w/o needing tons of power pushing the sub(s).

Mine has a XXX 15 in it, run by a hifonics 2006d, and hit 145.4 in my trunk car.

So, they arent crap , and they hit HARD as hell, and get loud.

Again, to be a horn, it must provide acoustic gain, which I challenge you to achieve below 50-60hz.

126dB at 44Hz, in a station wagon, from two 4inch 5 watt rms midrange drivers, with an FS of around 100Hz...

trust me, cabin gain isn't going to do that //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

no he doesn't, he's a n00b

Blow me.

Blow me.

guess that proves it. lol

You got a problem with people that drive station wagons?
No offense, but you're one of the few people in here that apparently knows why a SS is special... care to share?

No I don't actually, and I used to have one.

It's actually taken me a while to learn all of this. So, naturally I don't want to just say "here's all the info guys, have fun designing them". So I like to give little bits of information, if someone is serious enough about wanting to know how to design one, they can do some experimenting themselves.

It takes quite a few qualities from different boxes, using each to its advantage.The closest box to it, would be a ported box //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

The weather is getting nicer out here and I intend on doing a bunch of videos with a termlab.So I'll really be able to see how much gain they provide in a real world environment.Same sub, sealed box, ported box, and my version of a "snail shell" and I'll give an honest unbiased listening review of all. I'm not afraid to say something sounds like shit, even if it is my own design.Way back in my early SS days a couple of the first ones I built sounded pretty crappy.But the mistakes helped me learn and understand more things about em'.

Are they end all be all of boxes? **** NO! But they have their place, like anything else.

I was still writing the other reply.

I'm fully interested in having a civil discussion about these enclosures. But you can't let anything like that happen, oh nooooo.

Whatever, I'm out of this thread.If anyone needs a little help and has any legitimate questions other than the usual "how do they work" "how do you design them" "can I have a design" etc. then I'd be happy to answer them.

 

[Death By Bass 10+ year member]

just because you used to have one, doesn't mean you know anything about them, or can design them (not that there is anything to design, seeing as they use pretty much teh same box for every woofer! lol)

 

[Pyro_By_Nature 5,000+ posts]

I didn't just "used to have one".Trust me, I've done a SHITLOAD more. Please know about someones experience before opening your keyboard lol.

ah, there's not much to do with a poorly designed transmission line //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

 

[Pyro_By_Nature 5,000+ posts]

Ok, go on thinking you know everything about every box every created............it's quite comical actually.

 

[UndercoverPunk 5,000+ posts]

I don't think you actually know anything. Your explination was so unbelieveably nondescript. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

That's why no-one ever gives two shits about these types of enclosures.

Think whatever you want, I don't give a ****.

Yes, because I did the research, I did lots of building and testing, and I'm not going to give all the information up just for some people on a forum to prove something.I took the time to find out different aspects of them, it was more like a puzzle.Learning about each section at a time.

Want to know all about em'? Start reading and doing research. It's not that no one gives two shits about them (there's still plenty of interest), its that most people are too lazy and want everything spoon fed to them.

All of the other people I know that know how properly to design them, also keep very hush hush about them.Because, yet again they also did the work.

Been reading too many Hexibase posts lately?
I especially liked this part:

"you need to understand the effects of the vehicle on the horn design itself"

I couldn't agree more! By knowing the effects of the vehicle on the horn design, I realize that achieving any acoustic gain at typical sub frequencies is pretty well impossible.

A horn, by definition, must provide acoustic gain by converting high pressure/low velocity waves at the cone of the driver into low pressure/high velocity waves at the mouth of the horn. This simply cannot be done in a vehicle at low frequencies. Many are foolish and mistake the natural effects of cabin gain for acoustic gain provided by the horn. What most have done is taken a ported box, made it look like a horn, lowered turbulence at the termination point in the port, achieved more directivity and experienced cabin gain. Again, to be a horn, it must provide acoustic gain, which I challenge you to achieve below 50-60hz.

Then I challenge you to come sit in my vehicle and prove me wrong, when I strap on some 34hz notes on you at over 145db with a pair of 10's..........over 150db at 44hz.

Prove me wrong, I have a horn in my car that's extremely loud, can you prove otherwise?
