4 channel setup. HELP!

Recommended Posts

I recently purchased 4 Crescendo  6.5 UN speakers and 2 FT1's. I also bought the Skar 125.4 (not gonna wait all year for Crescendo amps). I got the crossovers for the tweets. I have no idea what kind of crossovers to get for the 6.5's or if I have to. I've never done a 4 channel set up so any help or tips would be awesome! Please dont make smart a$$ comments. I'm new, no help othet than YouTube and I would like to be able to do all of my own work.

There is no crossover that will make that combo sound good.  Even with a $300 processor you are going to have huge uncorrectible gaps in the frequency response.  

To get this to work you need a real tweeter.  The ft1 wont cut it.

I've seen that you and a few other's have said that. All of them I've heard in person sound amazing so that confuses me. Nonetheless I was wanting help with how to do the install. I was hoping to get some info in that area because for some reason I can't find anything.

Your idea of amazing has a really low level of entry...

You are going to need one heck of a processor to get anything out of those.  FT1's have no use in ANY install.

Mids around 150hz (HPF) - 5000hz (LPF)

Tweeters 5000hz (HPF)

You wouldnt want to run those mids that high and I didnt care for FT1s at all. If you cross your mids lower then you will have a gap in your frequencies between your mids and tweeters. Also with runing your mids so high you will have another gap between your subs and mids. Something i wouldnt recommend at all unless its an spl rig.

 

I think what sounded awesome to you was the fact you could hear the music over the bass, not necessarily the supertweeters themselves but I could be wrong.

What may be happening is that the frequencies being produced, may sound decent.  But, you might not be noticing the frequencies that are being missed because of the gap in the frequency response.

And the wicked anomalies in the frequency response.  Sugar pill of acoustics is volume but there are such better ways to sound "good"

Listening to electronic music or rap you probably think they sound fine, play any music with "substance" you will notice a HUGE gap in frequencies.

So if i sell or trade these off what so you guys recommend. All I really listen to is bass boosted and rap songs. I rarely listen to anything else.

What does it need to blend with?

The UN's are also a problem.  You need a midbass with them.  Balancing a pair of X15's with your music tastes ought to be easy enough though.

A nice pair of dome tweeters will do the job, no need for four mids either. I run a 15" and only have one pair of mids and one pair of tweeters and they keep up well. No rear fill either, means i don't have speakers in rear doors or my rear deck. The way my rear deck jumps around I wouldnt put speakers back there anyway.

///M5 I don't know how many times I've asked for help on here and the only thing you do is come up with something negative to say about whatever it may be and provide absolutely no help to what I  asked help for. I'm all set on your type of "help". Thanks.

Brandon, help is much easier when it is asked at a time that help can be given.  Perhaps an analogy would be helpful.  Being you are from Michigan I will assume you are somewhat of a car guy.  Here is the question I heard asked.

Let's say you own a 1970 Chevelle with a 327 V8.  You go to the track and someone gives you a ride in their 1970 Chevelle with a 454.  The 454 Chevelle rips and gets you super excited.  Instead of asking how to make your Chevelle fast, you ask the guy what he is running for an intake and carburetor.  The guy with the 454 car tells you he is running a Holley Strip Dominator intake manifold and a 950cfm dominator carb.  You run off and buy the same intake.  Your next step is to install it and tune it so you go on a car forum and ask.

Of course the response on the car forum is, wtf??  You bought a big block intake and carb for your small block.  This won't work so they don't respond nicely.  You take it personally and react they aren't helping.  This is exactly the situation we have here.  The FT1 is a terrible tweeter, the UN's are ridiculously short changed in their frequency response and don't at lend well to a standard car installation.  Making them work together and sound good is not possible.

You can verify this a bit by yourself.  The Fs of  the FT1 is 2800Hz (hard to read their complete lack of specs which in the first place is a no go for buying anything by the way).  Normally this would mean for a safe and easy crossover you would cross it over at 2.5x Fs or 7000Hz.  Take your phone, download Funcgen and then play a 7000Hz, 10000Hz and 14000Hz note.  Realize that this is what that tweeter will play "musically" and how small of a range of music it is.  Then play notes at 1200Hz (where my tweeters are crossed at) and realize how much of the frequency range you are short suiting yourself with.

I know my "help" hurts since you already spent money, but it is cheaper to fix now than later.

The mid drivers I have no problems with. Depending on installation, should be able to play with crossover settings to make things work for your application.

No as far as tweeters go, I'm with Sean,  You can do MUCH better with than what you have. I couldn't actually sit and listen to the ones I've heard in the past. 

 

Good Luck

Randal, you do realize that below 250Hz or so they are completely unable to do anything without a ported enclosure, right?

IMO, that is not capable of blending with ANY sub setup that makes sense in a car.

Yes sir, I understand.  Maybe he can work with them fudging numbers to make something work since he has them. Worth a try ???

My main thing with the post was on them screaming tweeters.

The fundamental frequency of the male voice is below 180Hz.  He listens to rap.  Sure there is still a ton of harmonic information even above 2kHz, I wouldn't want my music to sound loud but like it is playing over a telephone.  FYI, phones normally filter things from about 300-3600Hz.

For his needs the gap to give up is the area ABOVE the voices.  That would fit his music listening desires the most.  Either way even with a driver that did do that the super tweeter is harsh and can't mate well anyways.  Has WAY more sensitivity than needed anyways since the rest of the front stage will still be much lower in level.
