The Next Masterpiece.

[Simmsled]

My roommate here at Purdue has a 2003 Hyundai Tiburon. I installed a great system consisting of the following

Headunit: Pioneer Premier DHP9300mp Front Speakers: Infinity Kappa Perfect 6.1 components

Rear Speakers: Infinity Kappa 6x9s

Subs: 2 Infinity Kappa Perfect 10s (custom box)

Highs/Mids Amp: JL Audio 450/4

Subs Amp: JL Audio 500/1

*amps mounted on custom amp rack

Cap: PowerAmper 3 Farad

Speaker Cables: all stock wires bypassed and 14awg used

Power Cables: Streetwires 4 awg

70 square feet of Dynamat all over the car, we stripped the interior to install.

So... we are going to upgrade to competition level. The next post is what we have planned. PICTURES TO COME SOON

[Simmsled]

These are the changes...

Headunit: Denon DCT-Z1 or McIntosh MX-5000

Front Speakers: Dynaudio Esotar tweeters and Dyn MW-160 or MW-160GT mid-woofer with a Dyn crossover X280

Rear Speakers: same (will not be used all the time, just to jam)

Sub: 1 Infinity Kappa Perfect 12 or 1 Precision Power Pro 12

Highs/Mids Amp: Precision Power Pro650

Sub Amp: same

Equalizers: Precision Power DEQ-230 30 band one per side only on front speakers

I have a buddy in Japan that is going to ship (export) one of those "Japan only (JDM)" headunits.

We are going to apply more dynamat, build custom kickpanels, and custom sub enclosure.

This project will be a meticulous buildup and will be a pain in the a s s. But d a m n will it be sweet.

Sub: 1 Infinity Kappa Perfect 12 or 1 Precision Power Pro 12

i have 2 - 12" Infinity and they are just enough base, 1 wont be enough

[lessthanjakejohn]

wow that looks sounds sweet

[ayjay]

damn... that sounds good man, can't wait to see the work in progress pics...

but i agree... going from two 10's to one 12 is hardly an upgrade, dunno if that'll be enough boom to keep up with those Dyn's in the front

the Dyn's are SWEET though, good choice :rockon

[Altiman94]

go with one 12w7 powered by a jl1000/1 then youwill see about a single 12 being an upgrade.

[ayjay]

uhh altiman94... i think they have some sort of budget to follow :pface

[Rex]

What kind of "custom box" are you using? Have you given any thought to the more difficult to build high efficiency boxes?

Such as...

[ayjay]

or how about this... it looks pretty crazy (for an 8" sub)

[Rex]

More than once, we've just slapped another of the same sub on the existing one (clamshell style) and doubled the amp or just wired it in parallel .

slimm - you say "custom" box, do you mena by shape or "function"?

[Simmsled]

All of those "high efficiency" boxes are coo and some are very entertaining to build and listen to. However, I usually stick to a nice second order sealed enclosure that yields a flat frequency response. I guess its just the audiophile coming out in me. If I'm going for super high efficiency and bust-your-nuts low frequency extention, I would make a ported box. The port(s) would be tuned to the lowest frequency that the sub could play, and then a sub-sonic filter would be placed 5 cycles (or 5 hertz) below that frequency. That would give me nut-jarring bass and is most effective at setting off car alarms while driving through parking garages. (an old past-time when I had my 2 Soundstream SPL 15s) ahhh the good old days. hehe

Here is a ported/slotted Beastly MOFO that is perfect for a Q45. The center slot would go up through the little glove box thingey on the rear parcel deck and the two ports would come up through where the 6x9s would go. This configuration uses a single 15 in the middle and 2 12s in the sides. It would probably eat your lunch.

The darker translucent red represents plexiglass. This combination enclosure sports three (3) single reflex bandpass enclosures. The design is intended for the trunk of a vehicle (Q45, but does not have to be) using two 12" drivers for low-mid bass and a 15" driver for low bass. The ports fire into the cabin via 3 holes in the rear deck.

The sides and bottom of the enclosure would of course conform to the contours of the trunk, and the 15" subwoofer would use the spare tire well volume if needed. The rear of the box does not even need to slope as the gas tank is right there in the Q.

The center slot port would be longer to suit the tuned frequency. I suggested frequencies of 80Hz to 140Hz for the 12" drivers, and 80Hz and below for the 15" driver.



I love car audio.

[Rex]

You mentioned the following numbers:5, 5, 2, 15, 45, 6x9, 15, 2, 12, 3, 45, 12, 15, 3, 15, 80, 140, 12 & 15.

Which brings up 2 questions...

Which one is the price for you to build me that box? andWhere do I put my clubs with that in the trunk?

But seriously, aren't those 3 tiny enclosures?

[Simmsled]

there are 3 tiny sealed enclosures within the "red" zone. behind them, there are 3 ported enclosures. This is a complex bandpass 6 chamber mixed ported/slotted enclosure. I would build this box, but I dont have the time as im now back at Purdue. i'll be back in a bit... colts are playing... GO COLTS!!!

[Rex]

If I understand correctly (& I may not), the subs fire from the sealed areas (red) into the ports enclosures. What would you figure the volume of the sealed enclosures to be?

Have you ever experimented with any aperiodic type sub systems?

[Simmsled]

This box is basically just 3 bandpass boxes that are all built together. Volumes would depend on which sub you would use. it varies greatly. I'll do some calculations and give you an example if youd like. Aperiodic setups are ok, if you have little space and big big woofers then it works out well. They can be tricky setting up though because its not just building a box and throwing it in a car... its using the car itself as part of the whole sub setup.

[whiterps13]

wow that triple bandpass is nuts. it would look hella sweet but take up all of my hatch space ;]

[Simmsled]

Ok, we have officially changed the amps to TRU Technology. More to come.

[Repo Man]

So, he take out another loan? Insanity...

[Simmsled]

Well... the C.E.S. (consumer electronics show) just threw a wrench in the gears. We are currently re-evaluating. This thread is pointless. AHGHHHH

[Touchdown038]

What programs are people using to design their boxes? Those both looked badass, I would love to design one like that.

[MECPInstaller]

or how about this... it looks pretty crazy (for an 8" sub)

Fancy transmission line box, perfect bass response insanely difficult to build correctly:) i learned how to build loads of different boxes using all sorts of formulas one called a tri-tune box i think everyone should take a look at makes any sub give off the same db as close to 3 subs making one 12 sound like 3:). might be alil hard to follow me but here it goes

box it made of 2 chambers, both the same cu. ft. sub goes in one chamber, one port per chamber(2 ports total so far). then both chambers are connected together with a flow through port. i've listened to a single punch 12" with 100 watts up when i was at mobile dynamics(audio school i went to in toronto) this box was nuts the 12 was hitting so hard it was shaking the rafters and out of a 60 dollar sub. anybody ever needs equations or specs on building certain boxes just give me a shout i'll type them up for you. also i'm planning on going into custom box building spent 500 on a box building program so if you need box built specificly for a certain type of sub i can do it

[Simmsled]

!!!THIS JUST IN!!!

We have now replaced the JL Audio 450/4 and the JL Audio 500/1 with a single amplifier, the Precision Power Art Series Ax606.2. Running it in the 4x50w and 400x1 (sub) mode, we effectively enhanced our soundstage, increased the bass, and tightened up the sound altogether. The next stage is to bi-amplify the highs/mids in the car with a matching 4x50w (at 4 ohms) power amp by PPI, the Art Series A404.2.

We tried just running the Infinity Kappa Perfect 6.1 system components in the 200w x 2 mode (bridged) and the 400w x 1 (subs) and the Perfects did not like it. I do not reccommend the Kappa Perfects for 200w RMS+ power. I think that the drivers could handle it, but not the passive crossovers. That is why we went with the 50x4 configuration and hooked up the rears just for some rear fill while we jam.

I could not believe that one amplifier (even though it is 2 feet long) could produce more sound than the 450/4 and 500/1 duo. But then again... thats Precision Power for you.

We sat outside the apartment building in the extensively (and I mean extensively) sound dampened Tiburon while the 2 Kappa Perfect 10's were shaking the apartment 3 floors up with the new PPI amp. The hot chick that lives there came down and yelled at us.

The JL setup is just not as potent or as refined as the 8 year old PPI. If you think about money investment, it would make sense. The PPI amp was $1,499.99 new in 1996 (the only year they made that amp) and the JL amps together cost just over $1,100 or something like that.

Now I know what to tell people when they ask me what is better than the JL amps or if PPI is better than JL... I'll say, the old PPI stuff gets the crown. I was hoping that it would turn out like this as I advised my roommate to get this amp off of ebay. I thought that it would beat the JL's, but I did not know that it would eat their lunch.

[ayjay]

gotta love the "ghetto feeling of greatness" that those PPI Art Series amps have :pface they look kinda fruity, with those wacky paintings on em, but they are amazing amps... good choice! TRU technologies amps would have been really nice too, but a bit pricey...

way to piss off the hot chick :ylsuper

[ayjay]

oh and did you draw out that box design in 3dMax? that's insane... too many calculations for me... i'm just stickin 2 bigass round ports in the box i'm building just cause they look a lot nicer than slot ports :pface

have you ever heard of a horn enclosure setup? that's similar to the aperiodic enclosure you mentioned, where the entire car is transformed into the enclosure... these guys called "Team Shadow", yes a purple Plymouth Shadow, had a setup like that with two 15" Titanium Pheonix Gold Subs and a single 1000W Titanium series amp runnin both of em... they hit an INSANE 154 db, and these were accurate mics. i couldn't believe that it was only 1000W they were runnin to hit that high... i guess it's all in the enclosure

so what kind of box did you build for the tiburon?

[Simmsled]

Yah ayjay, the PPI Art amps look like a little kid drew all over em. For the people that dont know what they are, they dont care and just think that the amps are poop. They just dont know.

The software is at the labs here at Purdue. It is some kind of custom software that has a funny name. The box is just a pre-fab dual 10 inch sealed enclosure for right now. We are waiting for warmer temps to execute a new system layout. Once we get all the stuff we need for it to be "proper", we will design somethin real nice. Im thinking fiberglass. I always love systems that look like they are special factory options. I love integration, so it will flow well and allow spare tire existance. We may even tap the PPI Art Series liquid cooling capability and do something with that. Cant wait.

[ayjay]

WHAT?? liquid cooling?? i had no idea................. :drooling

[Simmsled]

Okay... so here is the scoop. We have been in talks with a speaker company called Morel. They are willing to sponsor the car and we are Elated. More to come...

[audtatious]

Congrats on catching the sponsorship...

Great choice of amps. I ran a A600 (origional) for appx 6 years bridged @3 ohms to a 12w6. Coustic RTA reported 136DB with 139DB peaks with that single sub.

Unfortunately, I had to put the amp out to pasture (it sleeps in a box in my basement) as it started blowing mosfets. Every time I would replace one (or two), a different one would blow.

Anyway, post up some pix soon...

[ayjay]

Morel??? damn man, that's a pretty nice sponsership... they make super nice components, up there with Dynaudio, Focal, CDT... can't wait to see what you get!

[Hellion240sx]

MECPInstalleri want to make a fiberglasss custom box and i would like for you to give me an idea. i have a 92 240sx hatchback. as of right now i have 2 10's in a ported box in my closet. in my carrecently, is a rf he2 or hx2. the one with the chrome face 12 inch woofer in a sealed box.the 12 is my friends but the tens are mine.

i had to take out the 12 the other day i think i either blew it, or blew my amp. amp has power but no sound came out???? i dont know whats wrong!!! oh well waiting for your response. can anyone tell me whats wrong with it?

also i was thinking if i made a box for one speaker a sealed and the other ported. would that be a good combo? ior is that just crazy?thankspeace
