It may be basic, but pl consider to explain - Active vs Passive!!

In lame man terms in a active setup there is individual amp for tweeters, and midbass and in a passive setup there are cross over which filter out the signals.

In a active setup one can change slopes and levels from the HU. But in as active setup the filtering is done by the passive crossover so the majority brands only offer tweeter level only rest is preconfigured.

How ?

Please do explain.

I do not know how this can be done ?

Please do bear in mind, we are talking about HU & not a processor.
A processor will allow you to configure the Mid-Bass & High & Bass.
However, I want to understand how you will do it from a Top of the line - Pioneer or Alpine or any other.

Does the HU give your 12 pre outs ?

Front High Out - Left
Front Mid Out - Left
Front Bass Out - Left

Front High Out - Right
Front Mid Out - Right
Front Bass Out - Right

Rear High Out - Left
Rear Mid Out - Left
Rear Bass Out - Left

Rear High Out - Right
Rear Mid Out - Right
Rear Bass Out - Right

Maybe I am off track.
Sir, please do explain.
Appreciate it.

God Ji I was talking of 4 way active. Only speakers+ subs, 3-way front and subs. The one HU I came across is Clarion HX-D2. Alpine HU+ PXA combo, Pioneer P9 combos can do it.

If one want the above combo one put to PXA for the same to get 16 channels with include 12 full range and 4 sub woofer.

Hi LBM !

With a processor - yes - sure.

However, direct HU doing it.....
You did mention the Clarion, but I have not been exposed to it, hence no comments.

The other 2 options are HU + Processor.

Else, one has to buy the Steg power Amps and put in the 'chips'
I am sure you know what I mean !!! All the Best !!!

You dont know about HX-D2..that is strange. Anyways here is some info about it...

Clarion India | HX-D2

Clarion HX-D2 Head Unit : Equal to McIntosh/Nakamichi/Pioneer P9 etc? - Talk Audio Forums

Ya with Steg amps the possibility are endless

[Technocrat]

B the Audi TT install which I had intially directed to uses HXD2 HU:

Here is it:

Bhagwan,

The Alpine 9887, pioneer p880 can do 3 way active. i.e. High, Mid, low. you can do a 2 way front plus sub.

The clarion HX-D2 which gunbir is using right now can do 4-way active. i.e. 3way front stage with sub. this is one of the best head units available.

The clarion hU has 4 pairs of preouts. It can't play mp3 or any other compressed format. it only plays Audio cds. Plus it doesn't have a built in amp. I dont know if the pio has it. the 9887 has an internal amp which can be switched off.

Re. alpine processor, it either needs the rux controller or a compatible alpine HU. The other alpine processor(650) i think is independent.

i hope im clear.

cheers

Correction the HXD2 can play MP3. I saw it play a recorded CD

[Technocrat]

Just checked with EVO6 I stand corrected yes it can not play MP3 since the cd was recorded I thought it was mp3

Sorry for the confusion

[sk456]

hx d2 no mp3 for sure

OT.

Hi sk,


Sk, how much did you buy the HU for? does it have an xo and eq? iirc, your HU doesn't have an xo but im confused about the eq part. what about mp3? sorry for asking too many questions.

oh, i will google the info if i can find something.

cheers.

P.S. - A lengthy audition is due sk. im gonna visit delhi soon and it will be an audio only trip. No distractions lol. I did listen to your setup for a few minutes but it would have been great if i had the time.

You are partially correct;

The Alpines cannot do active.

The Clarion can.

If I may explain [try].
In any active set up, you need 2 things.
Individual Amplification for each driver & Active [veriable] X-Over.

This I think the Clarion offers. The Alpine does not.

I have posted what is needed, 5 to 6 posts above, please do take a look.

Thanks,

Clip, I reckon you are asking about SKs HU, the Kenwood K-CD01. No, its doesn't do anything apart from playing audio CDs to the best of its capability. No MP3, No EQ, No XO. It does have 3 full range preouts, of which one pair is a sub out. It only does level control on the sub out.

Sir actually Clip is right. The Alpine 9887 CAN do 3way active. You have a switch (under the HU IIRC) that you have to select to the active position. Then when you power up, the menus will change to an active setup menu. The Pioneer P80 also does this in a similar fashion.
