Cheers.

Its not true that 9887 is nothing without imprint kit.

You don't really need the imprint kit to make 9887 perform to its maximum. The imprint kit is for noobs

You were able to spot a peak and dip at 7KHz in two HU's by listening to them. I must say you have very good ears .

I hope you are not using Microphone based measurement in RTA to compare the frequency response of the two units.

Also peak or dip at a certain frequency band will not affect the staging to that extent. In case of 7KHz its way out of crucial midrange area.

The problem could be with your 7KHz tweeter / midrange crossover point and slope settings.

Well my ears work well enough for me to form my own opinion. So I don't feel the need to go anywhere to have another's opinion forced down my throat.

Having used both HUs myself, I tend to agree with Zucchero... simple. The P80 is a nice HU too, but I would prefer the 9887 (by itself) over the P80. And while looks are very subjective, I prefer the 9887 again.

I don't think Zucchero started this thread with any bias. He posts very seldom and when he does, he has something to say. We found his listening impressions quite akin to our own, while your review is quite confusing.
No offense meant.

before comparing we made sure that both the hu were in FLAT mode without any eq settings.

@zucchero:

Good to see the attention paid to keeping "all other things equal" for the A/B...

I did not knew that the imprint is for noobs.

Me not alone Zuchero singh is also agreeing with me here. And thank for the complement.

For what sir. also I dont have a mic based RTA with me.

So what it would be. I would like to know your experience. What caused it in your case.

I dont think so because the Midrange and tweeter are working with there passive networks and not Active.

I addition to this If you are interested in knowing today again I and zuchero singh did one test. I boosted the 8 khz eq in the HU and the soundstage was higher when compared to flat setting. What caused it maybe you can tell us.

the whole Idea was mine but Zucchero singh helped with his ears.

BTW, whats that cable in the pic(blue and red in colour)?

cheers

You are the first person say that never heard from anyones who knows what it can do. Anyways no need to debate with you as you have a very weird type of choice. And what other equipment which you meant ?

The blue and red color is the power cable for the 9887.

No offense bro.

Cheers.

If you are running passives then the crossover point is 5.5KHz not 7KHz.

So a peak or dip at "7KHz" has more to do with tweeter and its placement could very well be the result of reflections because of glass area.

The sound stage is more dependent on drivers, locations, phase, slopes than equalizer.

You can improve imaging by equalizer as it makes the reproduction more linear by eradicating peaks or dips in frequency spectrum.

All I want to say that the peak or dip at "7KHz" alone cannot affect the sound stage enough to notice so easily. Moreover the cause of this variation has more to do with the speakers and car acoustics than CD player.

Me thinks that Zucchero prefrs the sound of th 9887 (over the P80) and LBM prefers the P80. This discussion has more to do with personal tastes than the ability of either of these HUs to perform admirably.

It is of personal but I also like the sound of 9887 no doubt in that. We are discussing how much difference two HU have. And what effects it makes in the soundstage and musically.

I think Zuchero singh will help me now as I am not able to explian. Singhaaa.

From reading your and Zucchero's reviews I think anyone who is that serious about music as to invest in either of these 2 HUs (neither are entry level HUs) should listen to both and decide which suits their ears/system/installation.

I agree with you on all the above terms. I would like to elaborate a bit. There is not a peak or dip at 7khz alone. I said it is at 7hz and above. Which can be at 8khz to 12k.

The main funda I am trying to say here is that with the 9887 the tweeter were playing louder when compared to P80 which shifted the soundstage higher simple. I said why 7khz and above because the tweeter is giving 7khz and above.

And the my tweeter is crossed at 7khz as it is running passive with the cross over which came with it.



Also the two-way Iridium kit is crossed at 3.8 khz.

Yes I agree. Investing in high end ICE equipment must be done seriously and only after listing to it. But here in india that type of resources are yet to be made. But T-Bhp is helping in a great way.

Oh. rest assured there are many who think the way i do. I would buy a high end Head Unit instead of a rux-pxa or an alpine HU-pxa combo. The head unit for me would be definitely the clarion.

Your dash with the head unit and rux looks ugly and IMO and according to me, your ice sucks. Don't know why. your equipment is good.

And thanks for not debating. I dont like to bajao a been in front of the LOW_BHIANS_MAKKER.

no offence
