Well it's finally happened.

The magical 180dB barrier has finally been broken on the Termlab meter (the world standard measuring system, as used for "dB Drag Racing").

Alan Dante recorded an incredible 180.5dB, raising his previous class record.

Outright in the world, Alan is now 0.7dB clear of Craig Butler in 2nd place and 0.8dB ahead of Scott Owens in third.

What makes his effort that much more amazing is that Alan is in the Extreme 1 class. That's right, he hit 180.5dB with just a single subwoofer!

Wow! That is truly an incredible effort.

180db, damm thats loud and with one woofer even better. How long before 190 falls? 5 years?

Thats AWESOME!!!

wow.

180's and sand bagging!!! Makes a laughing stock of everyone else in the world. Hats off to you Alan

incredible, top effort

Awesome!

Congrats.

Jesus christ 180 with a single woofer. Congrats

Amazing!

Considering it wasn't that long ago when we thought that 170 on Audiocontrol was phenomenal!

I Honestly didn't think it was possible at all and that I wouldn't see it in my life time, let alone with one woofer!

180 on LAB is like what 194 on Audiocontrol?
Maybe 200 on a Qld Audiocontrol hey Phil?

Sweeeeeeet.

that's funny considering all of us, here in Australia, whinge and b**ch about people being soft. We are WAY TOO SOFT guys.

WOW!
certainly gives us something to aim for

tha's just outa control....... congrats 4 this alan.

It is awesome effort by Alan Dante.

He used a single DD 99Z18, the same that any customer can buy.

Phil

without being rude or having a dig at anyone how come were so far off the records? is it money and sponsership?

Nice one!

hey Phil, the Z series amps are comparable to the stetsom amps in terms of output yeah?

it's cause we suck

nah it's mainly the money and time, no one over here wants to spend the money, and the time to build a car up. and then there are the excuses of no Panda's avalible in aust LOL haha

but awesome effort! i remember the days "its impossible to break 180db, it's physicly impossible" and "its impossible to break 170db, it's physicly impossible"

the reason Australia is so far behind is WORK and their being no competition here to drive people to work harder.



Overseas, Europe in particular the really stupidly loud guys spend more time on there cars than they do at their paid jobs.



The test everything and anything to get every 0.1db



The other advantage Euros have is the number of events held and the proximity of these events to competitors (thanks to the size of countries) Living in europe you could be confident of there being an event pretty much every weekend and not have to drive more than 500ks to get there.



Despite what many people think, not too many companies offer full ride sponsorship, yeah, some will do competitor pricing, but this doesn't make it "cheap" just no so dear

i thought some pioneer guy in the US already broke 180. that wasnt on TL or am i dreaming all together?

Scott Owens / Pioneer do 179.7 from over a dozen woofers.......

Phil

X2...

and wasn't it a single woofer as well?

*goes off to search*

Pretty sure that wasn't certified That Pioneer truck is now 3rd, as Phil mentioned.

Thats an incredible feat. Props to him!

Umm, NO......

1st 180.5 Alan Dante - 1x DD 99Z18 - first dB Drag car ever over 180dB
2nd 179.8 Craig Butler - 6x DD 99Z12
3rd 179.7 Scott Owens - 13x Pioneer 12"

Phil

It's a shame it's mostely box design and port possitioning. Still good to see that score but it's not exaclty 'real' spl.

Scott Owens doing a 180.4 last year

Not dB Drag on Termlab.

There are several different meters, not all of them read the same.

Alan Dante is the first man in the world to go over 180dB in dB Drag, on Termlab - the world standard for SPL competition.

Phil

what meter does IASCA use??

AC??

TermLab too AFAIK but i think a different metering system

Doesnt the Termlab sensors only read upto 182db or something? Wayne Harris might have to develop new meters soon!?

Audiocontrol SA 3056 SPL meter with the SPL 190 pressure sensor.

Phil

IASCA uses AC with 3055 meter and SPL190 mic/sensor.

Too late Phil got in before me

so what's the theoretical measurable limit of SPL?

surely it must be close?

- Stooge007 out

When the TL explodes you've won

I herad somewhere it was 185 but not sure of that 100%.



Something to do with speed of sound or something i am realy not sure just something i remember hearing awhile ago.

SPL is as I understand a not a finate measurement, its just whether we have equipment and vehicles to measure and capable of withstanding it.

The Term-Lab sensor is capable of withstanding up to 200dB, but they are configured currently to around 180dB.






THat made me a laugh hehehhe

Hey Phil, how much is that sub by the way?

See attached.

Phil

I'm not an SPL person but credit where it's due - that is one hell of achievement, and I don't even want to THINK about the amount of time, miney and effort that would have been required to achieve it.



Nice

at 185db (well, sound pressure) air starts to turn to water, so it shouldnt be long and we will start seeing clouds being formed inside peoples cars

Alma Gates was telling me a tale of 190dB, and spontaneous combustion that was alot of scotch flowin' that night.....she's a great lady



Dante is still standing on the beach....true #'s will be shown in 3 1/2 weeks

Yeah apparently he is only using 26,000watts to achieve the 180.5db. And the 99z18 can soak up 40,000watts

That term sand bagging is a killer

We get asked all the time. So much so that I grabbed this chart off the net and linked it to our FAQ section.

Its technical because it depends on the atmospheric pressure. At 1bar just under 194db is achievable, and at 1bar pressure level this is the maximum - 1 bar is the atmospheric pressure at sea level.

What makes it possible to surpass this number at sea level is the ability sound has to change atmospheric pressure levels.

I was getting a sore neck.....

Phil

I don't think that logic is correct as the sub is 'creating' the pressure, which although related to atmospheric pressure, can be above and beyond this.

Correct, but I covered that, "Sound has the ability to change pressure levels" The more compressed the air the louder something can be.

Take for instance a blue whales call can be measured at upto 180db, this is because of the pressure the sound is under. The secret to getting super loud is being able to contain the pressure in the car.
A car that reads a massive score on the Term Lab shouldn't sound very loud outside of the car. The quiter it is outside the car the higher the score, potentially.

202-198 (P) HUMAN DEATH FROM SOUND (SHOCK) WAVE ALONE.

OMG thats crazy....

Suicide by DB.... lol imagine that...

still comes second to asphyxiation caused by female breasts

friggen insane scores btw.....brilliant stuff

hopefully we might see a 170+ car over here soon hey..?

Very soon.

Phil
