can somebody please explain whats the difference between active and passive?
please post some links for my knowledge.sorry for the interruption.
In active setup, the mid bass, highs and lows are split at the HU itself. In passive setup, an external crossover is used (same as what we get with the copmonent set).

Most Americans I have discussed this with, have told me that almost always everyone agrees that's special because "if they say that it must be so, I can't tell the difference anyhow". Another (childhood) story that comes to my mind is "Emperor's new clothes"!

Humour apart, does the TA system ask you whether you are driving the speakers active or passive? Or does it ask you "Are the mid-bass and tweeter sound like sitting on each other now with the current settings"?

I guess if we are trying to achieve so much precision as 'closeness of tweeters to the mid-bass', we have to use the same amount of precision in the complete ICE thought process, including instrumentation to confirm hypotheses. Otherwise, like the Emperor in the story, the low and mid end will be 'revealed', the soundstage will shift to rear, and we will be left chasing illusions instead of listening to Illusions, right?

Are you running active or passive ?
It was just an expression abhibh. . What i meant was one can get full advantage of the TA when there is a dedicated channel each for the midbasses and the tweeters.



Right now i am running passive but you never know.

Lol.

But then when you are active you can fiddle around with the TA for the tweeters as well.
When you have 4 dedicated channels for the front - 2 for the mid basses and 2 for the highs, then you can align all the 4 channels seperately while when you have only 2 channels, one for the left(mid+high) and other for the left, you cannot individually align the tweeters and the mid basses.

I might be wrong though.
I am just a learner.

Arrey Gupta-ji, 'fiddleability' is no indicator of certainty of obtaining good results. Most things follow the KISS principle.

the KISS principle?



By the way in your opinion, isn't TA better applicable in a setup with seperate channels for all mids and highs than a passive one.

Sorry to interrupt, DA and Guptaji, your nice discussion (I'm following it closely and learning many things)- but here's a basic question on TA- does it always, invariably and inevitably create just one sweet spot for listening, or can we manipulate the system somehow to create at least two sweet spots, if not four?

I don't think.
TA is done to make all the sound come to the ear at the same time.
I don't think it can reach 2 different points at the same time.

Default back to the topic now!

Ok now, before you guys go deep deep deep into the TA world talking about what not, things that goo absolutely above my head. Only thing that does sound correct is that sound should be heard by ears. Not the brain. Hear it, fiddle with it, hear it again, fiddle with it again, and then again keep on hearing and fiddling till you are satisfied.

I, Chirag, Abhi, Rushi(friend) met today to TUNE chirag's system. Armed with just a screw driver and 4 pairs of ears, boy we did a good job. (Yes I'm boasting. ). Don't ask about the tech stuff from me because I haven't a clue, but, do ask about the sound because that I do know something about. And for everyone saying TA doesn't make this difference then and this difference then, go listen to Chirag's car. Once with TA, once without. It's like differentiating a peacock from a hen. Chirag my friend, you got an amazing kit of stuff there. Hold on to it. HEAR it. Do not hear to what the OVER TECH world confuses you about.

By the way, change the sub box to sealed or else you'll seriously end up sending a Saree or two flying with the shear amount of AIR from that sub.

Abhi, do me a favor, post the video of the little pod dancing.







cheers
bharti22shresth


P.S. (Chirag's neighbors came out running just to heard what the whole ruckus was about, and we hadn't even turned the mono "on" then)

Thats really nice to hear that he is enjoying the music.


Its not that TA doesn't make a difference.
It does.
Great amount of it especially to bring the sub up front and integrating it with the front stage.
But i wanted to say that a TA on a setup with dedicated channels for mids and highs would be better than the one in a passive setup.

No, since IMHO I wouldn't be able to tell the difference. TA is about time of arrival at the ear, not innate high frequency qualities. If the tweeter response is (relatively) shrill, it will stay shrill (bright), and not become less bright, nor make the wave appear with any more accurate delay.

Actually, it is your brain that is making you do the fiddling! If you just hear it (like they say "with you heart") you will go along with the lyrics, rhythmics and notes of the song without trying to split hair. If you want to listen to music, let your brain rest.

Of course you should boast! Shabash, that's the spirit!!!

By the way, how did you 4 agree with each other? THAT is the most surprising thing.

I and abhi have near identical taste for music, chirag and rushi have similar taste for music. Hence we just tuned the setup so that it can go BOOM when the occasional "kida" comes up and rest of the time sing melodiously. Though it will be more to my liking if the tweeter position is dealt which it will be. Soon.

I'd have to say Abhi. Why? Because I'm not much of a fan of a back massage.

AHA! Well said. OK, CHDbhpians, Rohit sir's giving us all a treat at BARBEQUE NATIONS this weekend. Anyhow, he will have to because most of us are broke anyways so, might as well be "besharam".
