Whats the differences betwen the 2-way, 3-way, and the 4-way speakers? Thanx (sorry for being dumb)

Number of drivers per channel. Assuming that you are talking coaxial type speakers, most of them will (2-, 3- or 4-way) will be totally outclassed by a decent 2- or 3- way component set.

ok...still VERY CONFUSED (sorry) now then what is the difference between coaxial and component? THANX

if it has a separate crossover (in other words, an actual device that goes between the output signal of the HU/amp and the speakers [drivers]), they're considered components. Cause then the signal would be

- HU/amp -> wire -> [CROSSOVER]=>wire->[individual multiple drivers]
otherwise, with a coaxial speaker,
- HU/amp -> wire -> [multiple drivers as one speaker]

[drivers], depending on the #-way set can be:
2 way: woofer/midrange, tweeter
3 way: woofer, midrange, tweeter
4 way: woofer, midrange, tweeter, a very high tweeter I think

Coaxials don't have that separate crossover. I think they have some kind of crossover-type electrical component, whereas a component set's crossover is an actual circuit system.

A component set's crossover does more than a coaxial's crossover-component, separating treble from the bass.

However, there are exceptions and I may not be right :).

cdt braxials?

Most 4-ways are bass (woofer), midbass, midrange, tweeter/supertweeter.

Coaxial-two or more drivers mounted on the same axis. Basically one midwoofer with one or more smaller drivers mounted in the middle of it for each channel. May or may not have an outboard crossover.

Components-each driver on each channel is mounted and wired independently. Almost always has an outboard crossover. Usually uses much better drivers than a coax.

so can all HU/amps wire into component speakers? Just to clear this up say we are talking about a 3 way coaxil that means that there is only a single voice coil powering the entire speaker, yet in a component speaker then (3-way) it has three coils, ie. one for sub, another for midrange, thrid for tweeter,? How would you wire a component speaker if the HU doesn't break the music down into 3 chanels( like how would you kno where to hook the wire up as in which "coil")? THANX

First, you probably would not be very happy with components powered from a HU. Almost all components are intended to be used with an amplifier.

As to your question: Better coaxials and all component speakers have seperate crossovers which distribute the power. Usually you would feed the signal from the HU to the amp and then from the amp the signal go to the crossovers, which have feeds for each speaker.

The attachment is an example of a crossover :

just think of it like this:

- with a component set, the crossover can be considered a "hub", branching off to the different speakers (the tweeter, the woofer, etc), but the input of the "hub" is 2 wires (positive & negative).

- with a coaxial set, there is no (distinct) "hub", but still takes in 2 wires - postive & negative

You're on the wrong track w/ the whole coil garbage. lets compare a 3 way speaker and a 3 way component set (and forget about coils, you were way off). A 3 way speaker will have input leads on the woofer, which is the biggest driver. Then there will be a pole coming up the middle of the woofer w/ two more drivers on it, a small one and a tiny one. You don't really need to concern yourself w/ the actual wiring of the set up at this point, just understand that from the input leads, the low notes will go to the woofer (bass guitar, kick drum, etc), and the higher notes (guitar, voices, etc) will go to the two other drivers, with only the highest notes going to the smallest one. The idea being that each driver can be made specifically for a certain range of frequencies and each driver will only play the ones they are good at, and overall getting a better sound. A three way component set will take the output from the HU/amp, and run it through a crossover network, which looks like a little amp (shown above). The job of the crossover network is to divide up the signal (lows, mids, highs) before it gets to the speakers. Then you have three separate drivers (woofer, midrange, and tweeter) which will each have their own output from the crossover. Advantages of the components being that: each driver can be made individually to be the best it can w/o having to worry about a pole coming up the middle of the woofer or having to incorporate the crossover network into the speaker design, and that there is plenty of room to make a nice big high quality crossover w/o space constraints. Hope I didn't confuse you even more.

It has nothing to do with the existence of a crossover either. I own coaxial speakers that have external crossovers. The difference is entirely on how it is mounted. Coaxial speakers are mounted as one unit. They are simple to install because you only have to find room for the woofer. The other drivers are mounted to it so they don't need their own mounting location. The drawback to most (but not all) coax setups is that they generally use inferior drivers in their construction and most don't have a proper crossover. Component sets have 2 or more drivers per side and they are all mounted independantly. They are a little more difficult to install because you must mount the woofer and then find somewhere to put, at the very least, a tweeter. Components usually use higher quality drivers than coaxials and almost always have an external crosover network.

Is there a need for the "woofer" to be in a box, b/c i would like to place 2 sets of component speakers in the overhead sound bar in me jeep, and it is just a streched out hollow metal box, and i was going to do is, mount the two woofers, two mid's and the two tweets all in the same bar? Will this work fine you figure?

You need to separate the airspace that each speaker is working in. Othrwise the woofer will color the sound of the mid. For something like that I would look at coaxials. There are also a few companies I have seen that make enclosures that mount on the roll bar of the Wrangler. You might want to search for one of those.

How poor of a sound would come from a coaxil as opposed to component? What if i were to just put some dividers...not air tight but tjust to partition it off, would thet work enought? How bad would it be with just some 2 way components...would the tweeters be effected that badly?THANX

The tweeters wouldn't be affected at all. With that kind of speaker positioning you would be just as well to get a decent set of coax speakers as components.

yeah put some money towards cdt braxials or polk/momo mmc series...i have them and i can't complain...just more low end since i love bass

My kappa 63.5i's have outboard Xovers does that make them componants? CC

Have you read the thread? The presence or lack of a crossover has no bearing what-so-ever on whether a system is considered a coaxial or component. If it has a tweeter and one or more midranges, midbasses, or woofers on each side that are mounted seperately, then it is a component set as in it is comprised of several individual components. If all the drivers (tweet, mid, woofer) are mounted as one piece, then it is a coaxial as in the drivers are mounted on the same axis.

you think I'd buy the kappa 63.5i's and not know the difference, Iwas trying to be funny, but I guess I failed. CC

I'm sorry the proliferation of newb stupidity has made most attempts at humor miss their mark. Try a ;) next time and us crusty old guys might see the humor, or just let an old thread fade away...
