Hey guys,

I'm working on another project,
and looking at a single 12" sub in the install,
it needs to be of excellent sound quality, very precise,
but also offer very high output (yeh yeh I know I want the impossible)

I've narrowed it down to three options so far.

I'm looking to spend up to around $700 - $1000 max.

JL 12X6V2 Dual 4 ohm (since thats all they come in)
Boston G5 12" Single 4ohm
Image Dynamics Idmax 12" Dual 2 ohm

I've got 800 W RMS available at 4ohm Via a Soundstream Amp (500 damping factor, 50+ Slew rate).
Not 2 Ohm stable.
the JL Claims it requires 400W RMS For optimal performance and life,
which should work fine in series (8 ohm) and I'd gain a little damping as well which is nice.
Unsure which way I'd go on the other 2. I think they need more power than 400w?

The sub will be mounted within 2ft of my ears, so it is important it's not sitting there coughing and spluttering, (which you normally would not hear in a sedan) However it's in a very small cabin, so output is dramatically compromised. The sub will constantly be played near it's maximum potential.

I'm limited to 25 litres, I can stretch to 35 litres MAXIMUM, and I want to run Sealed only.

what are you guys opinions on these? and what other serious options are there?

thanks.

Very small cabin?

How small?....the G5 isnt exactly 'tiny'

I'm very curious about the IDmax..

any experiences?

I'm leaning towards the JL at the moment.

sorry i voted for the idmax just because i like them... but that was before i read your very detailed requirements... sorry i couldnt really help you

[Wasnt Me]

Umm i'd go the IDMax as i have heard it in Drew's Ute. He's got 4 idmax 10s about 1-2ft behind the driver seat. And it sounds like ummmm words cannot come close to explaining the aural heaven I was experiencing.

No you dont have to have 4 to sound good, 1 12in will be more than enough for loudness, and precision but 4 just looks damn sexy!

Build the right box (about 1- 1.2cu ft) and the 12 will sound as accurate and fast as a 10 but with a bit more volume. 800w will make the IDmax sound very nice. Obviously more is better ie louder. =D

Do a search on Northfield Drew's black hilux if you have yet to see it. It's on here somewhere.

There are some other subs that I think you might need to consider
1. ARC Audio Flat Series designed by IDMAX
2. Sound Splinter Premium series
3. Adire Brahma
4. DLS Iridium
5. DLS Nobelium

sorry... i voted IDMAX because i have it in my car and it never let me down...

[chanhonam]

I vote for IDmax as well, heard it in a member car, love it and its good enough for what i want from a woofer (dont want to get myself deaf)

IDMAX12 v3 D4 is out of stock for while now, there is D2 around.. so really depent on how deperate u need it? and what sort of power ur amp can produce (stable with 2ohm or 4ohm)?


Cheers

You might want to look out for the new Eclipse 8000/8200 series, uses LMT (Linear Motor Technology). I'll find the graph that compare to JLw6. Hard to beat SoundSplinter Premium series given the price.

there u go, if u understand any of it

You better explain what that means.. :S

[Reza]

Well if u look at W6 graph, the BL factor started to decline as soon as the cone started to move, now ideally u want to maintain the BL factor as flat as possible for better control and less distortion. The 8200 on the other hand maintain a flat BL curve which should translate to more accurate sound and less distortion.
The graph were posted by the engineer from TC sounds, they offer JL Audio this technology but JL turn it down saying that it's not possible to do it.

yep ok,

well I range my local eclipse dealer,
the 8200's are not In Australia yet.

not for awhile yet.. so that might be out of the question

trying to find out about the image dynamics atm.

I know not many people are reccomending the JL,
but i find it hard to not take it seriously, every review I read they love it to death.

JL use a linear motor in their w7's iirc.
Just like Adire use one in their brahma, and RE use in their XXX.

Some people like em, some dont.

Tough choice out of those subs, try and have a listen to them if you can, i'm sure all would serve you very nicely.

Yep ok,

well the W6, everything I read about it, it suits what I'm looking for,
as far as quality and output is concerned, Precision is very important to me,
although I will give it up a little for output,

I don't expect any of them to be as precise as my Focal,
but i do expect almost double output than the focal for the same size.

Juls

[killaklown]

thats a tough call i would expect an idmax to match with a focal.
And u havent even put the oz audio me into your options apparently an awesome sub in you price range and should be able to fit into the box requirements

[APS]

Plus there is the Treo woofers and dont dismiss the Rainbow Vanadium or Amboss woofers.
