Does any know where I can find some info. on these. I went to the PS4 site and it didn't really help. I'd like to see an internal drawing, diagrams, anything. Has anyone built one? How did it sound?

this isnt about the snail shell encloser, but can you build me a box for two 12"L5's ??

give me a few mins, and i will dig up some plans for a snail shell

Sorry, i cant find them on termpro.com a few people posted the plans for them, but they seem to be gone now

A generic layout of the snail shell won't work all that great...the enclosure is dependant upon the woofer...

If they didn't charge $3-400 a box I'd give em a try...

i have one, and could measure it and give you the basic dimensions. mine was manufactured by virtual technologies, and i assembled it, then had it sprayed with rhino linings. i also have one of their woofers, which are specifically designed for their boxes. it performs incredibly, and is supposed to be the equivalent of two woofers of the same size, in a standard ported or sealed box. this particular company went out aof business about 2 months ago, how do i know this? i was working on a sponsorship with them, being as they were a local company. there's a local audio shop that builds enclosures o this type specific for different woofers. they call them waveboxes. they aren't as good as the VT boxes, but they are close. that audio shop is sound sensations, located in marietta, ga. i'll check and see if they have a website so you could possibly contact them about this. as far as how well these type boxes function, they work well, with the woofer i have for that design. i am trying to get my dimensions down for one that i am wanting to build for the new woofer(s) i am getting, as soon as i decide on which ones (single 13W7 or dual 12W7's).

Hope this help's out! I think one of the secrets to a snail shell is that the port diameter should be a little more than half the size of the cone of the sub that is being used! If you look at one of PS4's videos you can tell this!

Here's a 12'' version - you'll have to play with it of course! They have to be built to the specs. of your particular driver and they cannot be tuned! Most of the time their tuned around 40Hz!

Are they really that much louder than a standare ported box? Has anyone compaired numbers? If so, I guess my next question would be: How do I know what dimensions to use for a certain driver? Particularlly a 15" Brahma. I'd like to try and make one.

got this off Trempro:

First off let me introduce myself so you don't think I'm just another guy who's infatuated with the Snail Shell. I'm Brian Johnson, I am a partner in Powered 4 Sound (http://www.powered4sound.com/) , the company who designed and manufactures the box.

What you have drawn up is a ported enclosure. You are using the same means and methods that are used to design sealed, ported, and similar boxes.

If you search this forum, as well as a few others (Team RF, Decware, P4S, etc.) you will find that many people are working on figuring out "the magic". My advice is, try and think outside the box. Think hard and with an open mind.

there are much easier, more efficient ways to get loud than using snail shell....those things are a ***** to build.

what does it mean by adjustable board?

DBfan187

what does it mean by adjustable board?

In the pic up above, it shows an adjustible board. The board adjusts inside the main enclosure to restrict/allow the amount of air to be released into the port! A snail shell works in the theory to use the waves inside the box to enhance the reproduction of sound! When you make one, just be sure to have the angled corners so theres no standing waves inside the box. The rest is based upon the "Quater-Wave Theory"

a theory that i have heard from plenty of people is jack. BUT yeah...just looks similar to using a backwave board...x-cept it actaully serves as part of the port. PLUS, listen to donn...he knows. peace

i agree with my homie donn:D. and yes it looks MUCH similar to a backwave box. once again i'm repeating what those who know more than me or as much have already stated. trixter if you really wanna be loud, talk to donn he's one of the best guys i know and always helps:D........even a moron like me:D

Try building a ported box inside a TL. Then tune the port to the fs of the sub. Then tune the line to the fs of the sub.

Are you a sado-masochist? Do you enjoy inflicting pain on yourself?

TL enclosures are all well and good for applications where flat response is desired, but they are very driver specific and even tho they do have a nice gain over simple ported, the gain is no where near that of several other types of enclosures (even silly old bandpass). TL enclosures are used a lot in HT applications where SQ is of the utmost concern and SPL is just a nice "by the way". If you want to get really loud, study up on bandpass and ABC. I'd show you a nice little diagram of a project we call "Black Beauty" but i've poured my time and effort into this baby for way too long to just give it away.......oh what the hell.....I'll share :)

And if you'd like to buy me some new subs for my daily driver, i might even tell you how it works :greedy:

i offered him like 80 bucks for his box designs he won't share. and he has a design louder than black beauty. trust me though you don't wanna attempt those without extensive reading up on bandpass enclosure's.

im about 15 minutes north of marietta. as far as SS goes, they copied their original box from a VT box. then, they made small changes, and made them woofer specific. but still, the VT outperforms any sub i have ever heard in one of their boxes. i know this as fact. my ex-gf had one of their wave boxes for a kicker comp vr she had. and it put out impressive numbers. the box was built specific for her woofer. i unloaded it, and put my VT RIP hammer in it, with the same amp. my woofer, even though the box was built to the specs for the kicker, put out 5 dB more than hers. my VT box is a little larger than hers, and has a little different specs, but the woofer still out performed hers, in a box that was built specific to her woofer. i like these enclosures, and yes, they are a biotch to build, and get the dimensions just right on. i have been working on figuring the dimensions for an odd shaped enclosure for a 13W7 with a snail shell port. and still haven't gotten them just right. its a little easier to figure when you have a square/rectangle box, but this one is not either of those shapes. so its a little tougher to figure.

I honestly don't think Donn will share Black Beauty's design. It's crazy though.

The other box didnt work as well as planned.

Bandpass=funny.

The booze is to drink first to make them look hot! Atleast thats the plan!:smash:

I used to shop at Sound Sensations too... too much. They were the first car audio store i went into and the only one i bought stuff from. I got one of their wave boxes then copied it pretty much successfully. But that was only after i started redoing my entire system in audiobahn... from them. I had the "WAVEBOX" built for a single 10" pioneer premier IMPP 1041DVC ( the Gold Coned ones). A few of my other friends got that same basic setup in thier cars shortly afterwards so i got measurement of their boxes and compared them with mine to pretty much find out what they did. BUUTTTTT i lost all of my research that i did with that on my last harddrive wipe :(.

Oh but back on the subject i think i know what you guys are talking about and i did some light research on them a while back... its either a TQWT ( Tapered Quarter Wave Tube or vough pipe) or a Horn im thinking it's the horn because it has the ability to make speakers go from 5% effeciency to up to 75% effecient which means that you would need 15 speaker to get the same amount of volume that you would get from that 1 :scared: . I'll do some more research i do have a few pics on here are these what they looked like somewhat?

And here is a website of where i found this information at. :) hope it helped. Im gonna try and learn how to make these... if they are for subwoofers. but i saw NOT BASSLESS in bold so im guessing that they can be for subs.

75% efficient, eh?

Not to be rude, but i'm going to call bullshit on that one......

Isn't supposed to be 9.2dB's higher than a sealed enclosure in the 30-45Hz range?

+9.2dB = 31.5% more efficient :)

If his design is 75% more efficient, it's going to be about 20dB over sealed.....

01-17-2004, 10:26 PM
The P4S guys have a box called "The Centerfold" that is rated 19.6dB's over sealed. It is supposed to use an "areopedic membrane"(sp?) What's the efficiency advantage on that?

01-17-2004, 10:43 PM
Try an abc box, i hear its much louder (and sounds better) then the PS4 box. It basicly have two tunings/two chambers and three ports blah blah blah.....and the box that was used to make the 6.5"s sound like 15s is much more complicated then most people think. And i have the design, muahahahahahaha!

I've seen plans for and an actual "centerfold box" and let me tell you, it's nowhere near 20dB over sealed....i'm beginning to think that you guys can't even grasp how much 20dB is....For example, Mr. Marley Skater Tyler Man is hitting 147's with his 18 in a sealed box. If we threw said sub into this magical mystery box, he should hit 167....does that sound realistic to you?

:smash: Me either.

I don't care if the virgin mary flew down from heaven and blessed that box, it's not going to be that freakin efficient.....and if it were, wouldn't all SPL competitors use it?
