People of Adelaide. As you know there is big new things coming up for Adelaide and this is one of them..The intrest so far has been good and now it is put to you..

I have offerd the use of my car (Suzuki handyman) as for youse that now it, you know how small it is..For youse that dont know it (It is one very small car)
As i said ive offerd my car and at the momment we have been offerd the use of a amp 2000 @ 2ohm and a head unit i will find. All we need to do is to come up with a budget (so a rough pricing will happen to see what we are up against) and it will be right away."We are looking at 12".....
So who ever would like to be involved, this is how it will work.
When budget is sorted who every wants to help out we start to save..Slowly get things we need and so on.... (Remember it is a fun and absolutly volentry) we can all help out on the getting the best deals on the stuff. ie wiring,wood, screws, glue, ect ect...

So if you are interested and have anything to add post here..

So far there are about 7 people involved the more the better...this is a fun thing and when all done go around SA compeating and advertising CAA..

ps. there is small fine tuning, but when all people that are interested have lets me know will be notified of everythink that is going on..!

I was thinking that the sub should be dual 4ohm or dual 1ohm. Dual 1ohm would mean that if I want to make my own extream SPL car you can get a couple of the cheaper digital amps that put out 1000w at 1ohm. Single 2ohm would be more efficient but offers less config. We might want to check out the for sale

Odessy batteries have also been worked out.

I have yet to speak to Ang and John.

Cool..Your a champ evlhomer....
A few more things to add.. it is not going to be a dear spl car..And once all involved the cost will be sort out between us all...so everyone will comtribute the same and the more peolpe that would like to help the cheaper it is..... Once all up we can go to the comps and promote CAA and have fun at the same time.

If ya look up "speaker manufacturer adelaide" in yahoo (do a AU only search) their are a couple of people that make speakers in Adelaide, might be worth somone contacting them and seeing if they can do us a deal. Any rules saying it has to be a car audio sub???

I like your thinking evlhomer.... fantastic chance for them probably to get some exposure... (of course by giving us cheap speakers )

Dont knock the tornados, they could be useful for testing the res frequency of the car untill we get a sub. That way we can have a better idea of what type of sub to get if we have choices. I once heard that people with MTX RFLs in Australia are not pulling very high figures compared to similar gear. Im wondering if this is because of their high FS??? Can anyone say im right or wrong???
so we might need a sub in a box that is tuned at the FS or just above and peaking at the res frequency, but then again im just pulling this out of my butt, no testing or theory put into this theory

SOME guys in the US aren't getting that high scores with RFLs because they aren't that efficient - but there are some guys getting very impressive scores in SS and extreme (IE will probably be going to the finals)

the high FS is a side effect of the very stiff suspension

but of course, as soon as you put the sub in a box, the resonant frequency(s) can change quite a bit

so it all comes down to "its all in the install"

Well if im going to be lending half my gear to the thing im not that keen putting 2 much towards it, maybe we need to find someone that has a good sub or wants to get one.

It also looks like i will be moving out some time in the next couple of months so next year I might start thinking of my own extream car. Does anyone know anything about the blanpunkt (or how ever you spell it) subs??? Their is a guy selling 2 15's for 500 or 1 for 300 in a chrome finish

SPL_MONKEY: You think you can help us out with this.

I actaully think we should go 1x15now becuase I think the Autobarn comps have a 1x15(or 2x12 or 3x10) class then a 2x15 class and using a wall at DB Drag comps will put us against 15's anyway.

-Ben_ra23...Money dont mean to much but it will help us ... (THERE IS NO PRESSURE WITH $$$) But we need nails screws ect, if you think you can help with anythink that is all we ask...(LET US KNOW)

-Bassaholic...Mate you know what im gunna ask.... Can you help us out with the box.. ......

-SPL_MONKEY..Can you help out in anyway..I think youll be a good person to have involved!!!....

If anyone has any ideas on were to get anythink from wood to glue anythink at all.... Go to were ever it is that you have thought of to buy what we need.Tell them what we are doing, and if they can help us out tell them we will advertise on the car with a sticker... Im willing to have stickers all over the car for those who help out" (WE NEED A BIG CAA STICKER)

For a start, i have spoken to car toys (Elizebeth)...They will be able to do us a good deal on the DLS SP12.. they sell them for $849 but they will do a deal on that price if we decide to go threw them... (IF WE BUY NEW STUFF THAT IS)....

DLS SPL SERIES- SP12 12" 1,500w per 2 ohms voice coil... (how is this with the amp Michael..?) this is just a small start!!

Lets see..... at my place we have a bit of 12mm MDF. 1.2 x 2.4 metre sheets. Not the best for making a box but maybe for the trim panel or something

I could probably get screws cheapish through my dad. Nearly any size you want. As he has an account at Plastamasta (plastering supplies store) thus getting small discounts on those sorta things. (hmmm just thinking might be able to get him to take ones from where he is working right now for free)

Fibreglass could maybe get cheap as well cos my friend knows people who build boats so they buy alot of it and so we might be able to go through them, I'll have a talk to him to see.

Hmmm I'm doing work experience at Cartronics in a couple of weeks. Might be able to see what they can do for some free advertising???

I have a hand cordless drill or two for box making duties. Circular saw. I have some, not heaps, of longish screws at home i could take and some shorter ones as well.

I think thats it yet again. If I think of anything more I'll put it up.

Steven.

Evil. If we go for 15's we are up against walled 2x15's systems in comps like Auto sallon, where as if we keep with 1x12 or 2x12's and keep the box bellow window height we will still be in street class, and usualy a better chance of winning, post winning scores.

Either that or we move up (prob wont cost much is any more) and go a walled SS system using 1 or 2, 12's or 15's.

Any way Sunday should give a few of us a good opportunity to talk about this.

Good to see we can get your help SPl_Monkey.

And BassA. u know we want a box design/help.

Arnt we putting a wall in it??? Thats why I was interested and why I said that we could use a 15. Otherwise i might have to build an extream car next year with 1x18in.

Dont cartronics sell Earthquake (they sold them when I was their last a couple of years ago)???

If you buy the HCCA's walkinshaw we could use them and give the amp a 2ohm load or 1 and give it a 4ohm load and should be able to hit 150+ with 1 or 2 HCCA's.

Box design is more of a trial and error than calculations (to a degree) as it is likely the cabin will be smaller than the box (havent seen the car yet)

in SS its pretty hard to get a single woofer to handle a box larger than the cabin!

but yes, we still need to do a bit of testing to get max SPL

i love the idea of a wall, there was a red car at the aas if i can remember he had a single woofer, i think he hit very high numbers..not sure if he came 2nd or 1st..Some one will remember......

Another thing i was thinking... Were can we do all this... If my car wasnt in the shed here id offer to all the work here...But my car is in the shed.....1stly is there anyone with a shed willing to make room for the poosuki, It will be in the shed while we are building stuff ect ect, will drive it home when the day is over...im trying to make it so i can get it here.... But if anyone has a shed that is willing to help us out we will be much appreciated..

Not sure where the car actually came, I think they had some problems at the end of the day. I saw that car a little over a week b4 AAS and nothing was done to it. I think it hit 146.x but since the mic at AAS reads lower than the local shops will should be aiming at 150 (always +). It ran a single crosfire 12 and crosfire digital amp.

i was under the impression it was a 15, but im prob wrong.

I think to have any impact on the AutoSalon (biggest event) meter (TERMPRO) We should be looking to hit 150+ on local in-shop meters. And possably 155 With 2x12/15's, 2000wrms and a wall its possable!

If you're looking for Sub's (any size). I might be able to help.

My folks own and run Lorantz Audio Service out of Melbourne. They manufacture Loudspeakers for bands, cinema's and nightclubs. Dad designs all his own speakers and is planning to release a car sub line (10's, 12's and 15's I think). I have two prototypes (12's) in my car at the moment. I know he just designed a car box consisting of one 12 inch and an 8 inch that is supposed to be very powerful (not sure ofthe W/m stats) and is rated at 300 watt rms I think. But I told him the box was too big because it was about 2 cu foot.

The only thing being I don't know what the rules are when it comes to sub's. Do they have to be from a Car Audio Company?

Let me know...

the impedance doesn't matter..

designed for a 12 volt auto sound environment, means exactly that - the manufacture designed it to be used in a car (as opposed to being used in PA speakers etc)

------------------
- A proud member of Team Gates - A proud supporter of the CAA SPL project

There's a fine line bewteen PA speakers and Car audio speakers...

But PA speakers wouldn't work very well in a car anyway...

Does commercially available count if anyone can buy them from my parents factory, because they do sel direct.....

They can design the right speaker for the application and make it a new product that they support. No worries there....

yes, commercially available means anyone can go and buy them (they really should be a specific product design, eg if someone rings up and says I want 2 of those 12" car audio subs, then they will get the exact same speakers)

as far as PA vs car audio goes, PA speakers would sound like crap in a car and vice versa

Ok i think everyone will agree... Xmas is coming around quick, so all the talking and sorting will be done now up until xmas... We will find out were we can get help from and i think stright away get some stickers made up if we have to, if the people that help have stickers get some from them and put on the car show people that we are keen, and who knows, it will hopfully catch eyes and people will see CAA and come on and sign up, .......SO keep the suggestions coming......

Okay, spoke to dad last night, and he's pretty keen to come up with the sub of your choice. He seems to think that to be commercially available he'll need to make atleast 100 of them, but he's happy to do that because he reckon's they'll sell.

To get him starting on the design front, I need to know what your exact plans are as far as sub setup and amplification. i.e. 1 15", or two 12's, etc... Dad suggested 2 12's over 15, as the two 12's will up being louder.

He has just finished designing a 12 inch sub for car that does 110dB 1 W/m (between 40Hz and 80Hz) in a band pass enclosure. The only fall back being that the enclosure is 2 cu foot.

So yeah I need to know details and I can get him started on the design work. Or alternatively anyone who knows a decent amount about speakers can contact me, and I'll arrange to a phone convo, but only if you know a decent amount about speakers. They are getting towards their busy time of the year and I don't want to waste their time.

Oh yeah, he'll be very happy with any promoting. I garantee the sub wont dissapoint. He'll make sure it does the job and more.

OK Guys I think we seriously need to decide what class etc we want to run in - this offer from Mr Lorantz is unbelievablably generous! I propose that at the commitee meeting on monday night (23rd Jimmy Rowes pub ) we get this sorted! Is it possible for the poosuki to be there so that we can quickly run a tape measure over it to see even approx how much space we've got to work with??

here is what I'm thinking

how about 2 15"s? we've got PLENTY of enclosure space 20cu/ft+ (ideally as much box volume as cabin volume, but we don't have enough subs and power for that)

I'm thinking a fairly strong motor - ie a Qts of around 0.3, fairly tall top plate, coil doesn't have to be that wide, but make it tall. average suspension stiffness - not to stiff, not too loose

I guess it depends on what parts he has available..

and impedance wise, a pair that can be wired for a 1 ohm nominal load

the aim is efficiency and excursion (obviously..)

The reason he suggested 12's instead of 15's is that it's better to have two 3 inch voice coils (one in either 12) than the one 4 inch voice coil in the 15 inch. Effectively with the two twelves you have 6 inches of voice coil which can handle the power a lot better without heating up as quickly and losing effeciencey. Hence the reason why all big world records (Cerwin Vega and the like) have all been done with heaps of 10 or 12's and not 15's. I think that's it, but don't kill me if I'm wrong. Something might have got lost in the translation between his speaker brain and my non-speaker brain.

Anyways, once the volume we have to play with is figured out (preferably with a diagram with measurements on it that I can have and fax to him) and the amplification paramters are figured out (rms wattage and impedance), we'll be able to talk to "Mr Lorantz" and he'll design the best speaker and box(s) to suit. That's what he does.

Cheers fellas.

there seems to be some miscommunication (mainly about how much power we have - or don't have)..

I was wondering why 3" and 4" coils?

we've only got 2000w@2 ohm (nominal),

if we get 2 (15"s preferably), they only have to handle around 1000w for less than 2 seconds
thats not taking into account impedance rise - but we can still load the impedance down, so the actual impedance is a little bit above 2 ohm @ the peak frequency

I was thinking more along the lines of not as wide, taller coil, for better efficiency and excursion

as far as BIG SPL numbers go, there are people getting 174-175dB with anything from 2 15"s to many 10"s - take your pick

Bass: If we are using my amp the configured normal independence must be 2ohm or more, blown the amp once and dont want to have to fork out the money for and also have to find another D2. I will be testing this with a multi meter. I know your going to say the independence will rise but if you want to use my gear (and im lending over $2000 worth), then thats the deal.

The idea of 1 15 is that you can stay in the lower division at the local comps (eg Small Car Sunday) and not have to worry about the MTX car. 2 12in subs will give more cancelation.

As I cant come tonight can you please measure the distance from where the nic will be placed at comps to where the wall will be built. At a guess if you then work out what sine wave has a wave lenght of a quater of that distance is our res freq.

Roddas77 do you have an idea of how much these subs are likely to cost (for the demo vehicle and customers)??? And how long they take to make??? And the possible XMAX??? The Barossa day is coming up if we go for 15's I could chuck them in my car and compare them on the day to my Orions with either the ported (about 7cubes) box or the sealed (about 2 cubes).

Once again sorry I cant make it tonight guys been a bit busy lately and have a exam tomorrow

evl : No idea how much they will cost. Wont be much for the demo vehicle I don't think, and no doubt there will probably be more than one design made for testing purposes.

As to how long they will take. That's another "I don't know". It depends on how busy they are and what is required to build them in terms of machining pole pieces, front and back plates and getting cones, surrounds, spiders and voice coils right. I doubt they'll be ready for October 20th, but when they are ready I know my dad and I will both want to know how they compare to your existing subs so you'll definitely get to compare them.

Possible XMAX? Is that a speaker term? Sorry, as it's a family business I tune out when things start getting speaker technical! There will be a data sheet on the product created before the actual speaker is made. We'll know then.
