how much better quality and sound will i get out of components compared to the 6x9's in my sig?

100x better

100x better

thats a bit much

maybe 95x better

id say at least 96X better




other words, components pown coaxial

Call it 97x, and STFU.

so, in my truck where would be the best place to mount the tweeters? in the door panels?

Huh, i dont know about you guys but the difference between old school Alpine premium 6x9 and some components like Polk or MB Quart that i heard was bass response, and the comps got louder on the treble but i would definitely not say he will hear a 97x difference. Id say that if you dont have a SUB it will sound MUCH better, but if you have a sub then the difference will be something like 25% better.


Edit:
sub- 4 RE8's in sealed enclosure wired to 2 ohms

LOL the only thing that will sound better are your vocals, any bass gained from the comps will be way drowned out.

ya, the way it is now is i cant really here the voice too good. im going for loud bass, but also sq so i can atleast here everything else

how do i go about choosing the size? should i just go with 6.5's?

Err well they have to fit your car so..

You need to put them tweets in your front stage.. Thats why you cant hear vocals very well.

well, ill need to get an adapter plate, or make one. cause right now i have the 6x9's.

If coherency is of any value to you, a coaxial driver will always have the advantage of being as close to a point source without actually being one. The only improvement would be a single full range driver but that poses a new set of advantages/disadvantages.

The center of the tweeter should never be any further from the center of the woofer by more than a full wavelength at the crossover frequency. For example, if the crossover point is 3k that amounts to about 4.5". Depending on the particular rate of attenuation per octave you will have phase/lobing issues to deal with if you decide to make that distance greater.

Something to consider.

that all just went way over my head! can you elaborate? say i get components, the woofer will be in the door, where in the door panel should the tweeter be?

Coaxials are just components with the tweeter mounted on the cone and the X-over built in...

well i knew that, i just wanted to know how much of an upgrade they would be from my 6x9's

Well, I won't tell you where to put everything but let me be more clear about what I was trying to illustrate.

Let's take the ubiquitous 2khz crossover point. Sound travels at roughly 1130 feet per second.

1130/2000 = .565'

.565*12 (to get inches) = 6.78"

So roughly 6.75" is the longest distance you would want to separate these components ideally. More than that and you will begin to destroy the constructive relationship between the two.

So I guess all the guys who build the Championship winning SQ cars are wrong...:rolleyes::crazy:

op somthing to think about...a properly installed component system will sound better than a set of coax's.....a poorly installed component set will sound worse than the coax's.....

You are forgetting about absolute/relative phase completly....

This is absolutely true but not all inclusive.

And please, there's no need to get sarcastic. That's what gets in the way of every constructive topic on this site .

I didn't get into the fact that steeper slope are more forgiving of separation and placement because I was interested in keeping this conversation simple going off of the OP's question. Indeed what's more important when large distances are involved is that the crossover point be much lower, but again, that's another detailed tangent to go off on.

And the day I let a judge in the lanes be the point of reference will be my last day in the audio field.

In fact I wasn't because I happen to design and build my own filters to suit the needs of individual drivers.

Try separating two drivers that are using a 6dB slope. That's the full embodiment of absolute/relative phase.

6dB slopes require the most from drivers with regards to smooth behavior and power handling abilities.

I think what you meant was 6dB slopes are for those who have an idea of what they're doing.

Are you helping the OP?

ok, so can you suggest me a good pair of components for around 100 bucks.
