Well, I got a little time today to install the setup. ***** though because I didn't have any time to tweak the settings due to the rain...

Here are a few pics of the build. I only took a few shots because the rain started coming and that my batteries died on my camera....

I am satisfied with the output of the setup as it stands now. However, tomorrow I will tweak everything and hopefully have a video shortly....

only downside, I kinda wished I would have coughed up the extra cash for the 2500d. ;) No worries, I can always get a different amp another day. LOL. :)

ya really, is that sopposed to help anything beeing made like that? never seen a box made like that before, the vent looks alot bigger than the airspace for the woofer

Let me know how good it sounds. I wanted to make one for my Brahma but wasnt sure if it was worth the extra time. Since they are very similar drivers those plans should work for my B15 as well.

Looks very well built. What size box is it replacing?

vasilios
06-12-2005, 01:43 AM
its kind of like a transmission line enclosure; a labyrinth of walls and gaps....super efficient. more so than any sealed or ported enclosure. roll off and any standing waves inside the box are completely eliminated....in theory, anyway....the transmission line is any audiophiles dream enclosure.

man thats tight, i was wondering about that myself, i posted about a t-line enclosure somewhere else, and they siad the box would have to be like 12 cubic feet or some ****, how can i calculate a box like the for my eclipse 9152ti 15"?

What year is that altima? Did u have a hard time putting that box in? The box I had for my 15" brahma was a pain to get in.

james33440
06-12-2005, 10:07 AM
This is a '01 Altima SE. And, actually I only mounted the back and the doubled front baffle to the bottom, I mounted everything else together inside of the trunk..... the box is a little too big to fit inside the trunk with it built. :)

how is the s.q ??ps nice box

The old snailshell, to me, just looks like a mass loaded ported box. With out the angled walls on the port, its hard to say it is a variation on a TL, as it is not even long enough to have a quater wave in it.

I'm not saying it sounds bad, I have not heard one in person to say anything. I would actually look forward to seeing how it does performance wise with your music tastes and such. I also wouldn't mind seeing how P4S designs these BS super boxes :D

JimJ

as it is not even long enough to have a quater wave in it.

It also doesn't have any stuffing in the line...so I doubt it's based off a true TL.

DIYaudio.com might be a good place to start looking.

BTW, I had a little time to adjust the settings, gain, etc and threw the EMNB disc #4 in, WOW!!!! :eek:

OMG, the bass is incredible from this thing...

Seriously reminds me of the XXX 18 I had. :)

What size box did the SS replace?
What are your general thoughts on the difference in output, and sq?

chinny
06-13-2005, 12:05 AM
yeah, what size is wich, the 12 and the 15

vasilios

Thanks man, I really appreciate it. Did you work up the design yourself?? What frequency is this enclosure tuned to? Is there anything that would help me come up with my own design?

uh oh, i think a certain company just lost a bit of revenue :P

james33440
06-13-2005, 10:07 AM
screw POS, I mean P4S.... they can say that it isn't a Snailshell all they want. It is but it may not have the internal appearance as there's.....

for instance, I could have done the inside better..... I could have rounded out more corners, use resin to smooth everything in, and instead of a "V", smooth it out to make it look like a "U".... I will do this later though. Right now, I am satisified with the output. :)

tRiGgEr
06-13-2005, 10:27 AM
To all asking about internal volume and tuning. If this is in fact a snail shell design, there is no pre determined internal volume an tuning. All snail shell enclosures are built without using a certain net volume or tuning. FYI.

If P4S is denying that it is one of there actual designs chances are it is not the actual design they use.

Granted they could just be denying it to save face and not loose any business. But if it is in fact not a SS lets start calling it a fake shell at least.

james33440
06-13-2005, 11:07 AM
No, this is the Snailshell from P4S. This is the "old" design that they did use. The design was drawn up by She's A Good AIM from the sounddomain forum. He bought a P4S Snailshell box from someone and he cut it open and measured everything.

However, the "new" design is smoother inside with more curves and what not. Kinda like I explained I could have done.... P4S boxes are high quality and that's why they are so much. Bottom line, if you have the time and the skill (with the tools), you yourself could build one that would look like the newer ones... ;) Granted, P4S isn't going to say exactly how the internals look. :)

tRiGgEr
06-13-2005, 11:12 AM
Sure you could build it but would it be right...

No one has the formula and design they go off of. So no one but the creators could actually design one. Now cutting one open would yield the dimensions for that particular driver. Was the box that he tore apart actually the XXX box???

james33440
06-13-2005, 11:27 AM
Yes, the box was made for the XXX 15. ;)

All the info is on the SoundDomain forum if you search for it....

I am in no way suggesting that POS, I mean P4S boxes are great. They are. I mean, if my setup sounds like this and supposively my box isn't right, then I can imagine how the P4S box sounds!!!!

:)


I guess it's up to the individual. Pay $300+ for a box or just build one for less than $150 and learn from it. ;)

Can you elaborate on the differences in the SS box and your previous ported box, once you get a decent amount of listening time in on it?

thanks. what's the deal with the double shot? anything "special" or different than a regular ported box?

9512ds
06-13-2005, 02:01 PM
its the same as the snail shell but made for 2 subwoofers

chefboyrlee
06-13-2005, 02:08 PM
from my understanding the snail shell is designed for spl. how is the SQ on these boxes?

9512ds
06-13-2005, 02:09 PM
the sq on my box is amazing imo it hits every note with accuracy never skips a beat or gets muddy on any types of music

GTonDubs
06-13-2005, 02:39 PM
i heard t line enclosures are the best of both worlds from what i hear, sq/ spl wise
i have been trying to figure out how to do one forever

james33440
06-13-2005, 02:44 PM
The single snailshell is "suppose" to be louder than a single double shot with the same size of subs. ;)

vasilios
06-13-2005, 03:17 PM
what happened to this thread at the p4s forum?

james33440
06-13-2005, 03:30 PM
^ the thread was deleted and I got banned from P4S. LOL.

I never mentioned that this was a snailshell the other members kept telling me that it was a great idea to build one instead of buying one. LOL.

The Snail shell is actually supposed to be SQL. A mix of moth SQ and SPL...

06-13-2005, 03:50 PM
if POS doesnt want to claim it, then you claim as your own design, and start selling them.....
what ever happend to p4s after all the money issue they had awhile back?

9512ds
06-13-2005, 03:52 PM
there still going strong

james33440
06-13-2005, 03:59 PM
From what I heard, P4S has to explain some stuff to IRS. That's all I am saying about that..... Personally, I don't know nor care. :) They aren't getting cash for a box that I can just build. :)

tRiGgEr
06-13-2005, 04:17 PM
Can You build me one for a RL-I8;)

chefboyrlee
06-13-2005, 04:39 PM
any one got the design for the double shot?
i'm interested...i might just buy it for $175.
i've heard some bad things about how they do business...anyone have any experience with p4s?

9512ds
06-13-2005, 04:41 PM
i bought my box from them with no problems what so ever

06-13-2005, 06:00 PM
1 year back then p4s was really hyped up, and RE was too, everyone was jumping on the p4s train and RE train, but now i havent heard of p4s, and there prices have dropped dramatically, dunno bout RE, havent kept track of any of those companys

james33440

i've seen a bunch of links on theory's of the snailshell and TL enclosure, but does anyone know a simplified way of doing it? all those equations look like chicken scratch to me, call me illiterate, but these boxes probably take many trial and errors to get right

Decipha
06-14-2005, 03:35 AM
your probably correct and most of the time after you build a box and listen to it for a while you think of ways you could have built it better

You're right, it does take trial and error...but the results can be worth it. There isn't really a simplified way, physics is physics :)

i thought i was the only one wt tweeters like that, lol.

I got my from an old peavey house box, it has a big horn tweet and 2 small tweets like in your back window. I have 4 of them, loud as a mofo especially when hooked to an amp...

I should hook that horn up, if cops pull me over i'll just say i'm the ice cream man, ll.
