guys damnping stuff i need........can any body recomned it......

[rsjaurr]

congratulation LBM praji!!!!!
And Did u pay for singapore iridium or Indian iridium??

Now i would seriously advice u to upgrade [for such a high class set-up] ur car to getz as it has better door panel to minimise the need of door damping.
Acc.to Gunbir,Getz is probabaly the best hatchback to install very good system like the one u have now.

LBM, wurth and the product frm Audison

I agree... Getz provides great damping for speakers.... I have a Xing with Hertz 3 ways in the front..and damping has been doen with great difficulty.......Still get a lot of external noise in the car as doors are very thin......
Had heard front compos on gunbirs getz.. external noise was almost absent... ....speakers flow seamlessly...

from where can I get wurth in delhi area

[low_bass_makker]

thanks guys i earlier had accent viva. I dont like the huyndi quality. i had to change my car shocks three times front wheel axle and what not in just 1.5 years time. over this my car has a milage of 6-7 kms in city with no brakes the viva has the worst brake i have seen in any car the abs comes very fast ....I was very disappointed by that car.

As i love music so much I decided to go for a small car as the system can perform best in hatch so i went in for a swift as it a maruti product easy to maintian and run with good milage. I can buy a skoda also but I dont like big cars . We have a corolla and a honda in my house But i barely drive them....I think u got my point........

This is probably the address and contact no..

First, LBM, congrats!

Now, From my personal experience with Wurth, I would recommend AZ comp damping. I have used the damping sheet pack, i thought it was reasonably priced and far easier to handle than the Wurth sheets.
Also LBM, i would also recommend you look at liquid damping for the panels upfront.

[low_bass_makker]

thanks a lot guys

will be going to wruth and az comp both to look at the products they supply

But i have to add more i have used the az comp 1 foot x 1 foot sheet to install the component on the door but now i want to fully enclose the door so that the 6 1/2 componet can get low freq out...

Here are some pics of the iridium

first we will go for the midbass


it is a non press paper cone with a 3 inch vc. first when i read 3 inch vc on a 6 1/2 driver i as shocked had waited to see it in real here is a pic of the same...



Nominal power handling 100 W
Maximum power 160 W
Nominal impedance, Z 4 ohms
Sensitivity, 1 W / 1m 89 dB
Frequency response 55-5000 Hz
Fs, resonant frequency 53 Hz
Voice coil diameter 75 mm (3î)
Voice coil height 13 mm /0,5î
Voice coil type / former Aluminium
Voice coil wire Aluminium flat wire
Number of layers 2
DC resistance 3,50 ohm
Voice coil inductance, 1 kHz 0,67 mH
Magnet system Vented hybrid
BL product, BXL 7,16
Max. linear excursion, X max +- 3,5 mm/0,14î
Suspension compliance, CMS 411
Mechanical Q factor, QMS 2,27

Mechanical resistance, RMS 2,75
Moving mass, MMS 16,6 gr.
Equivalent Cas Air load, VAS 12 liters / 0,434 ft3
Cone / Dome material Non press paper

now comes the mighty dome....


here again the dia is 3 inchs which is again a unusual size for a dome midrange........
Nominal power handling 100 W
Transient power 160 W
Nominal impedance, Z 4 ohms
Sensitivity, 1 W / 1m 91 dB
Frequency response 250 Hz - 8 kHz
Fs, resonant frequency 250 Hz
Voice coil diameter 75 mm (3î)
Voice coil height 6 mm / 0,24î
Voice coil type / former Aluminium
Voice coil wire Aluminium flat wire
Magnet system Neodymium
Magnetic gap height 4 mm / 0,16î
X-max +-0,5 mm
Dome material Doped fabric

now the tweeter



it is a 1.1 inch dia tweeter

Nominal power handling 60 W
Maximum power 80 W
Nominal impedance, Z 4 ohms
Sensitivity, 1 W / 1m 91 dB
Frequency response 1 - 25 kHz
Fs, resonant frequency 900 Hz
Voice coil diameter 28 mm /1,1î
Voice coil height 2,2 mm / 0,087î
Voice coil type / former Aluminium
Voice coil wire Aluminium flat wire
Magnet system Neodymium
Dome material Hand treated fabric

now the crossover



One thing bad about them is that the midbass and the tweeter on one crossover and the midrange on the other

The crossover frequencies in the system are approx. 350 Hz and 7 kHz

more details will be coming up soon......

You know what's bad about that? It's not the fact that you have to juggle 4 boxes rather than 2. The really bad part is that, although you techincally have the option to bi-amp since you have a seperate set of inputs on both crossover, you can't bi-amp such that one amp takes care of your mids and tops, while the other powers just the mid-basses. I would consider that desirable. I wouldn't see the point in bi-amping with the mid-bass and the tweeter on the same channel of an amplifier. That's unusual atleast.

this exactly which is going round and round in my head, the same dito thinking so right now i have decided to stay passive till i get a good deal on amps in which i would go 3 way active......

One thing i like to add more i barely listen the rear speaker which are in stock location of the rear door I only run the fronts only man they surely are something........

maybe because the tweeter and woofer only need Lp and HP sections the midrange needs both so they made they divided the XO this way. If you were biamping youd just bypass the LP section of the XO.

.. I can forgive an iron core inductor (given the space constraints of a car) but polyester caps are not big there should be no need for ANY electrolytics on a speaker of this class/budget and the resistors aren't that hot either.

Agreed sir... I have never been impressed by them... I tend to compare them with the Mille's 3way crossover, but then the MLCX3 crossover alone costs US$800 a pair so its a bit unfair...

[low_bass_makker]

I agree with navin and gunbir both of u the crossover are bulit in a different leauge but the installs where i have see the iridium used are 100% active not in a single one I have never seen a install in which these crossover are used.....any ways till now i am in a dilemma wether to go for active or stay for passive till the subs arrive.......
