Apart from the installation and XO challenges, what are other Pros and Cons for 2 way and 3 way component systems.[/QUOTE]

Pros: better reproduction of critical midrange
Cons: management of crossover is more complex

try this. Active between bass driver but passive between mid and tweeter.

it is quite normal. a 6" that goes from 60Hz to 3kHz is not going to be as accurate in the midrange as a 4" midrange (and I do not mean midbass, I mean midrange - a midrange specifc driver is not capable of reproducing much below 300Hz).

Yup, a semi active setup can sound quite good with little effort.

Yes Navin Ji was running the DLS that way untill I had a 4 channel amp. The Mid bass was running active and the mid range and the tweeter was passive.

I think it was the easisest to tune. Earlier it was running full passive but at 290 watts, then later semi active/passive with 160 watts each side. And then finally ful active with 80 watts in tweeter and mid range and 155 to the midbass.

If we compare the output the best was the active one but the best to tune was the semi active/passive one.

it all depends on the XO freq. and drivers used. I would even suggest pushing the envelope and using a series XO between the mid and tweeter (esp if they are very close together and can tolerate a 1st order XO). another option for XOing the mid and tweeter is a PLLXO.

How would a 3 way, with the mid bass in the rear, midrange & tweeter in front sound?

Would a sub still be needed?

a piece of info from the above link:

Personally, what we choose is based on install space, budget, and level of sound quality we wish to achieve. A good 3-way system for car audio makes sense in a larger vehicle. Installing the midrange and tweets in front stage, midbass in rear doors or panels can sound great and well balanced. Add a sub and viola... you have it all. A true 4-way full range system.
Can comments on this set???

Let us say we get a 2 way setup with good midrange(300 to 5k), high(5k to 20k) for the front sound stage. Can we have a pair of 8" woofer for 30 to 300Hz(are these available here??) for the rear. Will this be a good set-up???

If such a set-up is possible, then does it solve this problem:

PS: excuse me for any mistakes, as I am completely a noob regarding the ICE.

I would not recommend having the driver seperated by a distance that is more than the wavelength of their crossover frequency. so that mean if your midrange operates from 300Hz to 3k the center to center distance between your woofer and midbass should be less than 1m (340/300) and the (c-c) distance between your midrange and tweeter be less than 10cm (340/3000).

Almost all the questions that I had in my mind have been answered. Thanks to the gurus - Navin, Gunbir, and LBM. Thanks to Hydra and LBM to share their first hand experiences on SQ, installation, and challenges.

If and when I decide to upgrade my ICE setup to a three way one, I will come asking for more suggestions on brands, acoustics, etc.

I have one more question though - if your HU has only 3 way active capability, how can we have a 4 way active set up (3 way front stage and a sub). Is it possible?

Yes it can be done but in that you will have to run two drivers passive. Like I was doing to run the midrange and the tweeter passive and the midbass and the sub active.

LBhiM..

navin mentioned something about using a "series xover" which I assume 1st order xover (i.e. it has a 6db slope) suitable for a situation in which the tweeter and midrange driver are close to each other.. I am in the same situation (tweeter and midrange will be next to each other).. The equipment has come, just waiting to get an appointment with the installer, probably next week..
I want to evaluate as many possibilities as far as x-over is concerned as I can and hence I need the details..

I'd also like to understand the details of a PLLXO in simpler terms than what is written in the link you've given..

Sorry for hijacking this thread, but here are the options I have in mind.

Amplifier: Audison SRx5
HU: Alpine 9853
Mid-Bass: Illusion Audio Electra 6.5"
Midrange: 4" driver
Tweeter: Illusion Audio Elecrta 1" Aluminium Dome tweeter.

First Option:
The Audison has a 3-way option in which I can use its onboard electronic x-over for midbass X midhi and then use the Illusion Audio Passive x-over for Midrange X Tweeter.

Second option:
Use the HU's x-over in 3-way mode for midbass X midhi and the Illusion Audio Passive X-over for midrange X tweeter

Third Option:
Use the Audison for Midrange X Tweeter which runs on the Front RCA output and use a dedicated 2channel amp for the midbass crossed on the HU XO

We sit in the car facing the dashboard. With this, can midrange and tweeter be on axis? If I am asking something stupid, please pardon my ignorance.

Which essentially means, I cannot have a true 4 way active setup if my HU has only a 3 way option.
