Mids or oval coaxial in front doors?

Thx TRiGgEr, well u see i dont have enough money to buy componenets too expensive, but i can buy a tweeter and a one way 51/4" mid + i can send different frequencies to every driver, i have enough amplifiers with built in crossovers. I guess this is what u mean by run active( i must high pass the mids from my built in amp xover, and also high pass the tweeter with much higher frequencies right?) Thx again guys

That's the general idea. But you're going to want to low pass the mid to seperate the drivers frequency range.

Hmmmmm low pass the mids??:S well in a case of a componenet i know that we must high pass the speaker and the passive xover will split the frequencies between tweeter and mid. Also in a coaxial 6x9" we must high pass it because if we low pass it the mid range and the tweeter will be destroyed right? Its the first time

i hear that we must low pass the mid, i know we low pass a subwoofer, but a mid doesnt play frequencies low enough to be low passed:S:S:S maybe i must high pass it at 1 Khz and start turning the level and decrease frequensies till it sound good, no? low passing such a small mid, i feel it will just start to make a humming noise:S i will try it any way ( high and low pass and see which is better)

im still a little confused of how you have that many speakers in the rear of your car:crap:

hehehe wonfused y man? these 4 speakers are 40 rms each, so not that powerfull, also i had them before i decided to install a music system in my car+ nobody would buy them from me cz they were not that powerfull, so i decided y not use all of them. I used only 2 of them first, b ut the sound was not that good, now with 4 of them my midbass is quite nice+ i will try to use some front speakers now+ a ts-w12prs pioneer sub. i will use 3 amplifiers( directed audio 1100D for hopefully two ts-w12prs subs), a profile ap1040 for my four rear speakers, and another amp for my front speakers. What i will try to do is sell the 4 rear speakers and maybe buy 1 set of decent pioneer coaxials with the yellow cone once and for all. But would it be better than using my four speakers now?:S thats what i wanna know. Thx

You low pass the mid @ the level your tweeter picks up at. If your tweet picks up at 4000hz then you need to low pass the mid around 4000hz. This is what the crossover on a comp set does. And if you're running active with two separate speakers, you need to do this your self. So low passing the mid is a requirement.

This is so the mid driver plays only the frequencies the tweet will not pick up. And will save you from dealing with cancellation.

well yep now i know what u mean and ur right but the problem is that the high pass on my amp is from 40Hz to 1Khz. I will high pass it at 1Khz for the tweeter. The low pass is 40Hz to 250Hz. So obviousely the tweeter is gonna get frequencies from 1Khz and up...but also i cannot low pass the mid, even low passing it at 250Hz means that frequencies lower than 250Hz are going to pass at the mid and thats not good no?? what if 80Hz...also are passing. So in my case better to high pass both the mids and tweeter. For the tweeter the high pass level will at 1Khz, and dunno about the mids. But surely they willbe some cancelations cz frequencies higher than 1 Khz are going to go to the mids and the tweeters also//content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif Also how can i know where is my crossover level, i cant know my crossover point( 200,230.300Hz) i only know HPF ( 40-1Khz) i cannot know exactely where my tuning level is So whats the solution then?:S How can we know at waht frequency the tweeter is picking up...i guess its all by trial and error and tuning by ear Thx again dude

You don't have the correct equipment to go active. So I recommend against it until you get the proper equalization/processing to go active.

I doubt your tweets can play that low. Normally 3500-4500 is the standard for tweets to pick up at. There are tweets that can play lower.

Do your tweets have a crossover with them, or built in???

Well almost all built in amplifier xovers have a high pass level not more than 1.5Khz, so how are they running tweeters?? I know that a set of componenets will be the best for my case, but sice i have tweeters and mids, i though that installing them, and high pass both of them is better than having no speakers at all in the front or i might use an external xover, hmmm m y system is becoming complicated:S The only problem i see when high passing the mids at 250Hz is that it gonna also get the very high frequencies too, as for the tweeters its gonna get frequencies as low as 1Khz
