High time to change speakers?

[pkhd]

I'm satisfied with rear GTx693 6x9 run by clarion576usb in my new santro. But the main culprit is front GTx401Blaupunkt sounds shrilling with chhan, chhan, chhan... Overall sound comes with sharpness and without sweetness of vocal.

I enough played my finger cross around in bass. treble. lpf, hpf setting but in vain. Presently i heard this setup by putting simply Digital Zhancer at 2 with all other settings at flat, which delivers wonder thump with high vocals but still I bear with shrilling sound with zero vocal sweetness.

Guys here, suggest way out,  if any? Should I think to opt front component or is there any other trick?

I am from home audio background, but the speakers characteristics are well applicable here too. GTx401 happens to be a 4 inch diaphragm. I wonder it can't give you good bass , even the mid bass.
Unlike home speakers, these in-car versions don't even have an enclosure..that makes them sound too 'treblesome'. Only way out IMHO is door baffles and larger diaphragm. In mumbai I have seen many installs making use of baffles (a small enclosure custom made on door).

They give almost the same warm effect as in home hi-fi setup.

excuse me, i didn't get u.

Baffles are made out of MDF or Particle wooden cylinders. It needs custom install on doors by cutting door panels down. A picture is worth thousand words.

@Vivek, you are right. Its same here in car audio too. Enclosure would definitely bring 'warm' sound. I have seen baflles being used in many custom installs. Only thing is, you need a very good installer to do this. Obviously, this technique is the best.

Other option I could think of is: Using the Kick panels. I don't know whether they are available in India. They are really a great alternative for someone, who is not willing to cut the car doors for custom install. (see pic)

oh having lots of  details now! thanks vivek & anil.

By the way, still confused how wooden baffles or kick panels works to reduce high frequencies with improving vocal stage?

I forgot to mention that my 4incher THx (not GTx) Blaupunkt coaxial is in company provided location fitted under plastic slot cover grill. I could not used metal grill of speakers coming with speakers, is this affect the sound.

any takers here?.......raghu, anil, vipin, bassfreak, vivek & others..?

Okay .. Baffles are really a good solution.
@Vivek, thanks .. It holds good in car audio too.

@pkhd, Baffles create kinda enclosure to increase the mid-range .. or vocals. It doesn't compensate for highs.

In general, baffles/kick panels allows you to move out from the factory location restrictions on size. You can go for larger speakers, say 6" .. meaning improved mid-range and warmth in sound. I am not sure whether ready made kick panels are available in india.

@pkhd, grills have no effect on sound. I guess the speaker size is the only factor in your case.. but I wonder why high peaks are hitting you.. we have done many many installations involving 4" co-axials.

[pkhd]

Thanks raghu.
I think adding component in front will sure improve vocal stage with reducing shrillness in front stage.

If I am right, is this the time to opt bigger size than 4"? which speaker-coaxial or component? which arrangement i.e. to cut the door or to go for such baffle on company pod? which specific speaker brand would be best fit to deliver my desired sound as stated in first para.

I amazed on GTx693 working incredibly in rear stage with thumb & sweetness of vocal. In brief, i want to reduce shrillness from front stage with mid improvement.

[Raghu]

I guess the issue is with the speaker size. For good mid-range, the diameter of the speaker matters. Adding a  component or coaxial of bigger size would definitely help. Adding a 4" component, I am not really convinced.

If planning to go for bigger speaker, say 6" , best is custom install involving cutting the door  pad and making a good baffle. It sounds awesome.

I guess we discussed this thing long back over phone and then zeroed on to 4" due to unavailability of  experienced & skillful installer out at your place.

u correctly guess dear raghu. so, again i come to square root one . Damn, where I can find good component installer here in gujarat. Is anybody here can help me out pl.

Check out the "learn" section for Speaker Boxes in Car Audio Installation - A primer on speaker enclosures.

[vicjain]

get them amplifed your problem will be solved.  and trust me 4" spkrs will not get damaged. and set ur treble at -3.

[pkhd]

@VCJain:- your notes really interesting. sure vl take some audition of front 4" thx401 blaupunkt with amplifier. By the way, I assume 50rms amplifier suffice for this 40W speaker. Which amplifier would be perfect fit then?

Also, pl enlighten me how can i connect my mobile/i-pod as aux-in. Ignore my knowledge if sound this basic question. I attached wiring diagram of Clarion 576usb for ready view.

[Vivek]

I think, you need such a connector. Then you can connect your any mp3 player output (the headphone out) to these aux-in on HU. See the picture.
