ShiZZZoN's Build Log

[effse7en 2]

oh god, this is THAT shizzon. I was really hoping not...

[Kanaworm$ 292]

and as always, we are still distributing Deka 9A31s for $120 flat.

How much shipped on the batts if you guys do ship? That is a great price!

[shizzzon 461]

like a said before, we don't ship because they are picked up in bulk. We have nothing to ship them in and possibly will get damaged if we did.

[shizzzon 461]

got another pic of progress so far..

Got the sides filled right now. Now, i'm workin on filling the void on top of the rear wheel well... hopefully i'll get that done today and get a pic of that.

[Sir-Lancelot 216]

You my friend take this very seriously. Wish I could sit in this one.

Agree, that is a great price on those bats!

[shizzzon 461]

Another pic so far-

I have to keep all these 2x4s ran across so the foam doesnt try n break out while it cures... I'll have to wait at least a day before working on this area anymore.

[mccleery3 166]

This man is serious Lookin good bro

[Soapbox 7]

Shizzon what class are you in?

[porkchop 304]

shizzzzon...be prepared to inform me on the batteries....

i could use a half a dozen myself....

and the meter as well....

perhaps a few fellars doing demos....

it will be great!

thanks chop

[shizzzon 461]

i can call my man and see if he has any extra if u need them now? if not, let me know at LEAST 2-3 weeks in advance so i can fill your request.

[shizzzon 461]

Shizzon what class are you in?

none now.. next year.. it will be Modified but i'll be sneaky about it

[porkchop 304]

um, read backwards and seen the 5'x8' 3/4" mdf.....

will be doing this too....

might have to make a second trip with the ol' dakota though....

chop

[shizzzon 461]

yep.. there have been some hiccups with gettin this stuff as it's been sellin fast but i can talk to the guy when u get here if u like and see where we stand on inventory.

[porkchop 304]

well, now, as in this saturday would be quite nice.....

but i will most likely not be powering any thing up for a couple weeks....

perhaps, for your convienance..... get me a hard measurment of them.....6 total

and i will bring the dakota down to get them and some mdf soon....

[porkchop 304]

will you use a closed cell membrane between layers ?

[shizzzon 461]

hadnt planned on it.. was planning on welding steel between layers of wood all the way around to prevent the walls from flexing inwards during pressure..

[porkchop 304]

hadnt planned on it.. was planning on welding steel between layers of wood all the way around to prevent the walls from flexing inwards during pressure..

i see, since we are on the subject, and i have been in your car before, have you designed a jacket of sorts to help prevent your passengers rib cage "from flexing inwards during pressure"..?????

nah, i had seen this application before with the closed celll membrane between the layers of steel and wood, had to do with the sound, resonance, aucoustical.....whatever....

but really, just was making small talk..... hollar at you when we get down there, you can help me plan some stuff out....

[shizzzon 461]

Hello once again...

While i am patiently waiting for the next few months for companies to contact me back so i can buy their products........ i'm going to start planning the next build...

But.. wow is there so many options...

So, i want others feedback on what you think i should do and why?

Car is 2007 Scion tC.

goal is to break 160.. if i dont, oh well, if i do, yay! hehe.

Specific goal- this is not a burp only vehicle. This is an averaging-mode vehicle so harder to get to that 160!

Options i have-

Option number 1-

16 10" DC Soundlab Lvl3s powered by a Single SounDigital 12Kw @35hz tuning.

Another option-

4 DC Soundlab Lvl5 18s powered by 2 SounDigital 12Kws @32hz

Another option-

6 15" DC Soundlab Lvl4 XLs powered by 2 SounDigital 12KWs @35hz

Last option i have right now-

4 12" DC Soundlab Lvl5s powered by 2 SounDigital 12KWs @ 35hz

This design is lined with concrete, hence why less cone area.

So.. what do u guys think?

And no.. I'm not doin 64 8s, lol

[B7L|BL4Z3R 4]

The 8s are always your idea

[ssh 924]

I'm digging option one

[shizzzon 461]

in a real world.. according to a graph.. the 10s are shown to produce the least pressure regardless of tuning including the low end

I do not know why i posted that as an option as i discussed it with a friend of mine that i more than likely will not go with that design ever...

Cancelation will be a major issue and it's the design with the least power and motor force.

That would work great for a 4th order but my car isn't large enough to attempt to do an averaging 160 in any type of bandpass.

[mccleery3 166]

I'm liking the 4-18's but the idea of those 4-12's plus some concrete seems very interesting. No flex issues in the latter design but will the suspension be ok for a daily driver?

[shizzzon 461]

the "other things" like weight suspension, space, wiring, electrical system, etc... has all been taken care of for each and every design.

All designs posted above already have a full start to finish layout for them to become a reality.

[Shogen 325]

Sick... My vote goes for the 18" subs... I wanna see that fit inside your TC...

[shizzzon 461]

OK, so we got 2 votes for the 18s...

1 curious vote about the 4 12s, hehe.

Let me toss this out there as a little bit more info about the designs being presented here...

The 4 18s will more than likely be housed in ~18-19cuft NET.

DC Soundlab has already assured me that with the power on hand, the volume isn't too small.

Tuned @35hz with 360sqin of port

The 6 15s will more than likely be housed in 22cuft NET.

This will allow them to be used in an enclosure which exceeds optimal requirements.

Tuned @35hz with 230sqin of port

The 6 15s have more motor, more cone area, more coils to dissipate heat, more volume...

But the 18s have much more port...... hmm....

And don't think that's not enough port...

My first wall was 4 15s off of 11,000w clamped in only 13.5cuft with 144sqin of port and pulled a 153.4db at the head and a 156.8 in the kick.
