ok i made a set of cross overs for a 3 way component system and, i was wondering what the ranges you all would set them at for each speaker tweeter, midrange, and midbass/woofer.
i know it depends on the speakers but i would like to see an ex: of one that some one on here has built from caps/inductors.

What type of tweeter is it? W/out knowing the speakers its hard to give an answer..
My last setup was crossed at 110/2k but that most likely wouldn't be optimal with yours.

see the problem is the speakers i am going to use i don't have specs on them. it's the component set in my sig and i was going to add the elemental designs EU-700 midbass for the lower end.
the only problem i'm having is setting the lowend on the tweeter (tweet from my PB components) it's set at 5k and from looking at alot of other tweeters like those most are able to play from about 2k on up
i built a 3 way Xover and the woofer has a inducter set at 800 at a 12db slop was going to use the eu-700's for this, the next range up is from 80-5k at a 12db slop and i was going to use the pb midbass for this the next range is the tweeter and it's set at 5k and doesn't have a inducter for the top end i am thinking that i need to lower this to around 2k or 2.5k but i'm not sure since i do not have the specs on the tweeters.

I might be wrong, but if there isn't an inductor wouldn't that suggest that the tweet is set up with only a cap which would make it a -6db or first order crossover? If it is, wouldn't that explain the high crossover point? (5k)
So, if you were to use the correct value of inductor wouldn't that raise the order of crossover (2nd = -12db) and allow you to lower the crossover frequency?
One option to try different crossover points is to get an amp and an active crossover that has continously variable points (coustic brand comes to mind) and wire each component to a dedicated channel through the crossover and try different x-over freqs. (as also suggest by Bostonian)
After doing this, you might just decide to go all active. But if not at least you have a really good idea how the components will sound.

500/5000 .......... +18db rated @ 400 rms per side
why would u want to run your tweet at 2k when your mid driver will do it just fine?
i run three 4" kappa's (100watts peak) on a home audio amp ( not a recever) that is 400 rms i will have a 6 x 9 kappa soon that i will run a 4th tweet off of the same "high's" crossover so that they can handle a lil as there my limit right now but the 4" could still move on... why the 6 x 9 will have a bandpass of 100/500

2k is a low cross point for a tweeter, a lot of high quality tweets will take it nowadays, but I doubt that is the type of equipment you are dealing with in this case.
And AZ is right...it is probably set that high as it is only running a cap/6db per octave filter, if you want to bump that up to 12 DB you will need to add an inductor.... 12 Db passive design
Go there, to item #54....about 7/8 of the page down you will see a line that says "For more information on higher order crossovers, go here."
Click the "go here" tab and you will see what to do. 12 DB should be fine, unless you feel like building multiple sets of x-overs.
