cross overs

[jonbearsmt 919]

well as some of you may know i had alpine type R components, but from the flex of the back deck, it broke my cross overs,

im going to leave the rear fill empty but i would like to find a pair of cross overs to keep with these speakers... incase i wanna sell them.. or i buy another lincoln i have a set ready,

my question is, what should i be looking for while shopping?

i see all kinds... but no type R's..... so i ask does it matter?

going by what you have in your sig, why dont u use the sax100.4 to go active with set you have installed and use the passive cross over from that to go with the other set.

They'll work with just about any 2-way crossover you get, they just won't work well.

Every single different component set should have a crossover optimized for its particuar drivers. There is no such thing as a "universal" passive crossover, you'll see them advertised sometimes that way, but it is marketing.

Do you still have the old ones? If you get me a close up picture of the guts from a few angles I can give you a schematic and help you buy PC boards and all the parts to build yourself a new set, a set that would probably sound much better...

Would probably cost you around $40

i dont think the alpines are worth taking active!..... and to be honest... i dont think i have the time to dial an active system in!

that is what i was thinking... the cross overs were made for the speakers it was with.. while i was shopping i seen some guts close to mine and some waaaay offf.......

i sure will take some pics and post them.. one of them in still in tact so just the leads are broken!

ill take pics this afternoon thanks!

There ya go, just reverse engineer the crossovers. The values and voltages should be be indicated on the capacitors and resistors.

If there is a inductor or two, it may be a little more difficult if the value isn't listed on the part. Unless you have a way to measure inductance. You can still probably use the same inductor/inductors if need be.

You could source the parts from PE. You can get into some nice metalized polypropelene capacitors for a good price, or even film and foil if you want to get particular.

There is the issue of microphonics with regard to passive crossovers when the mounted inside of a speaker box, when ran at high levels. (vibration from the woofer)

I've never had much issue with this in home applications that I can tell, but the listening levels are lower.

Of course you have the passive xovers externally mounted being a car component speaker set, probably close to the subwoofers?

If the SPL from the subwoofers is enough to crack and break the PCB boards to the passive xovers, then I think maybe the microphonic issue may apply here......

So when or if you build the new networks, you may want to take that into consideration and maybe damp the crossover networks real good, or maybe even pot them. Build 'em so they are impervious to vibration, and won't break.
