just bought a new clarion 12 inch sub i'm in love with it its running off a sony amp atm but im putting that in the front and putting the us audio amp i bought to power the sub

such a clean sound couldnt go wrong for $ 150

Congrats on the Clarion. :D

I myself am a loyal Clarion sub person now. I used to work at an electrical susperstore type place that had a huge car audio section and for some reason all my work mates in that section told me to steer clear of Clarion. I went against their advice and went with 2. I think that they are GREAT subs, ive never ever had any problems with either of them ever. They've never failed or sounded anything less than 100%!

GO CLARION!!

What Model is it ??
Got pics of the install ??

nah its just shoved in my old sony box its the new one out ill look for the model later but it dont really look like a sub

Clarion subs are ok.. didnt stop GTVBOy from blowing one up though. :bowrofl:

haha, with what....his headunit? :P

imho, i dont find clarion as appealing as dd does :P GOod if you're on a budget, or looking for some smokey fun. besides that, i would probably never get a clarion sub

Close.. a Boss amp :bowrofl:

No i would take the Disco Diva anyday. lol

Havent hear too many clarions. I'd imagine them to be better than the Boss, Rockwood, Sony, and probably above the Jaycars. They look pretty cool

OT... on the subject of DD's 2 brand spanking new DD1012's soon to be on their way. Just need to run them in once they arrive then in they go to see how smooth these babies are with SQ.

Peace

my dd2515 will pwn ur two 12s in my ported box!! :bowrofl:

just wait till i get a sealed box nigga! it still won't be anywhere close lol :doubt:

Ill just stick my Boston 12.5 in a 2cuft ported box to own you all :badgrin:

You want to seal you Disco Diva why? How big do you plan on having this box? Why did you get the 1012's for tim? Suppose there isnt really any difference between the 10xx and the 20xx series. Then you really have to go to the 35xx series to find something better. :badgrin:

I reckon if I put my mind to SPL I could pwn you in db drags with the two 1012's.

Luckily for you SQ is still the setup so these won't be pushed too hard. Maybe I'll install them into my girlfriends Starlet. Then nothing but pwnage for SPL.
As for who will give the better SQ... boomy 15" SPL woofer in spEekification sized box... :doubt: :P

Peace

What did you get the 1012's for tim? Suppose there isnt really any difference between the 10xx and the 20xx series. Then you really have to go to the 35xx series to find something better.
Went the 1012s cos for SQ they should give the same performance up to their power limits as the 3512s. All the internals are the same and same lightweight cone and tough design.

The higher the DD series usually just means they can handle ridiculous amounts of power for SPL. I only have 880 w rms to play with for subs, the 1012's can chew that up easily.

Also did some research and the 1012 is more suited to a sealed box than the 3512. The 3512 is more for ported, which I don't want to go to just yet as I need the low end control.

Was either this or the IDmax/Re XXX/ Brahma route. And dont want to spend that much money atm. Oh and Megatrons XXX had wrong voice coil setups for my amps.;)

When it comes down to it, Bass only makes up 10/150 for SQ, I want something that can drop down low... for cheap. And these should be able to do that easily.

Far enough, The 35xx series use a Synthetic Fiber Blend (SFB) cone, the 25xx use a multi-fibre non pressed cone and the 10xx and 20xx use a multi-fiber blend cone. I dont get that though if the 35xx is based on the 95xx series and the 10xx series is based on the 35xx, doesnt that mean that the 10xx is the same structurally as the 95xx series?

How much did they cost you if you dont mind me asking? I didnt think that the EBP would be that different between the subs are they are all optimised for the same boxes. If i blow the 12.5 again i may look to DD for answers. :D

hmmm, it might be just a marketing gimmic lol they're all based on the 9900 series simply coz thats teh flagship and phwar, if mine's similar to it why not!

my cone looks like paper mashe! lol

Thats what you get for buying off e-bay :bowrofl:

Hmmm RRP$250 for the 1012, in a huge ported box just for SPL.... why not :)

EBP was 50 for the 1012 and like 78 for the 3512 from memory. So both could work in either, but ones more closer to the magical number.

I can buy the 9000 series dustcap and make it look exactly like the 9912 from the front. that costs $59 i tink. But I cant see me doing that in a rush

As for cost, it is easy to get two 1012's for $450 brand spankin new. No one stocks in Vic but not too hard to get them shipped in. But let me test mine out b4 you go buying any... For all I know this little experiment could go horribly wrong and leave me scarred and burnt with no ear drums...

Unlikely... But anything's possible. :P

woohoo hometime...

Well in the perfect world, even though the cones are slightly different but the suspension is the same then they still should be bloody loud but sound sweet as. Results should be interesting. Boston Acoustics lie, they say the 12.5lf is optimised for a small sealed enclosure yet with an EBP of 55 it responds way better down low with a 2cuft ported box tuned to 40odd Hz with the response curve being almost identical to a 0.94cuft sealed box but with the curve further into the low zone. Not sure how it would sound, have a 1.75cuft box tunes to 23Hz that i could test it in :bowrofl:

Clarion are good quality, Sure their not DD or IDmax but they do what they are suppossed to do .. Make Low end Bass..
Clarion did make a 32 inch sub.... $3000 Brand new..

Tim i was actually doing some reading and out of the 10XX, 20XX and 25XX "apparently" according to DD the 20XX is the best of the lot for sealed enclosures as it actually uses a similar lightweight cone as the 35XX series and for some reason the 10XX and the 25XX use a differrent cone. It also has lighter suspension over the other 2 as well.

Me thinking 6th order bandbass box with a 1012.... :think: Now what to tune it to. :drool:

1012 EBP = 50
2012 EBP = 71
2512 EBP = 65
3512 EBP = 82

Not saying that sealed boxes will always be superior as ported boxes do offer many advantages. But just going by the EBP the 1012 suits the sealed best in theory.

And also $100 less per sub.

Peace

Tim

Far enough, you pay the $100 for the cone I suppose. In theory yes, but you can prove it he he. Ok quick question, in SPL comps they score for you output between 20Hz and 80Hz. Now in theory ( Physics ) you would need more power ( providing the response curve was flat ) to make a 20Hz tone over a 80Hz tone but is that significant, obviously not as much as say 200WRMS to move a sub and 20WRMS to move a super tweeter. Wouldn't playing a 80Hz tone be less damaging and require less power than a lower Hz?

With my limited and untested SPL knowledge: The amp itself finds it easier to play the lower end of the sub freq range near resonance than the higher end (eg would be under less load driving a 30 hz tone to reach 120 db than a 100 hz tone to reach 120 db all else constant with a sub)

Many other factors come into play as always. Lower isnt always better, eg: when playing below the frequency of the port/box design. But generally the lower the better.

The lowest frequency output will always be driver limited. That is the woofer will reach it's maximum excursion (Moving a lot of air)

The reason the amp is under more stress creating higher sub frequencies is due to the acceleration of the drivers moving mass. When creating lower frequencies there are less cycles (obviously) so the sub doesnt have to accelerate the cone, stop it then move it the other way as much.

Quick way to test this is to wave your hand throught the air side to side 1 metre as quick as possible. *Note how much wind you can make.

Then try moving your hand side to side 10cm and try to generate the same wind. Notice ur arms hurts. Pretty much the same effect with the sub cone.

Hope that made sense,

Peace

It Takes more Power to generate lower notes..
Look at your Amp illumination when a Big Bass hit Comes in.. It dims..
An Amp struggles to cope with Low notes.. Drivers Struggle to create High Notes..

Have you ever seen a Tweeter with an Inch of Rubber ??
True the higher the Note the more stress it will put on any Partuclar Driver Hence the reason why Tweeter Burn out alot Quicker then a Woofer.

Low Notes are Driver AND tuning Dependant..
A Poory tuned sub will have greater diffuclty handling Lower notes as the suspension will be bottoming out long before the note is reached..

A Properly installed Driver and tuned in theory should be able to reach down to the desired Note...

The Lowest Sub I have ever heard was 32hz, Human hearing can only detect between 20hz and 20.000Hz...

When Playing a Cycle outside the Tuning frequency of Driver, Damage can occur..

Major SPL is Achieved when Playing at the Resonant Frequency of the Enclosure/Vehicle with as much Power and Cone space that is available ...

Cool just wondering as my sub "peaks" at about 77Hz to 82Hz although there is only 1db difference between 62.28 and 130.9Hz off the peak. Well in my sealed box anyways, so me was thinking 70Hz tones due to the cars Fs as well. :D

To find your rough Resonant Frequency follow this formula..

1) Measure the distance from the rear of your vehicle to the fire wall Measure it in Feet
To convert inches to feet divide inches by 12.

2)Use the Following Formula to calculate the *Wave and 1/4 Wave

*wave Resonance = 1130/Feet/2
1/4 wave resonance = 1130/Feet/4

Using a Test Disc, Play a Track that sweeps all over the rough Estimate Resonance Frequency and listen for where exactly the loudest Tone is Generated (a Db meter is handy but not everone has one)

Most SPL Test discs will have the Hertz listed as the track number..
Play Cycles that are around your Calculated Frequency and go up and Down until you find your Peak..

* Test Discs can Damage Equipement if used incorrectly..
You do not need Excessive Volume to find the Resonant frequency.. 1/4 Maximum Volume is recommended when using Test discs and all Bass Enhancement must be set to flat..
