8 ohm tweets and 4ohm crossover

[BLD 25 10+ year member]

Just curious as to what happens when you use 8 ohm tweets with a crossover made for 4 ohm tweets. There are many good inexpensive tweeters that are fun to mess with from partsexpress.com, but very few passive 8 ohm crossovers. I don't want to go active just yet, but maybe this summer when i have more time.

I am pretty sure that the xover point is cut in half, but what else happens? Anything?

thanks

yea it messes with the crossover point, other than that i'm not sure what else it does.

Because using pre-built generic crossovers is baaaaaaaad.

yea, go active. it's not really that hard.

not trying to threadjack but is it possible to go active without a headunit that has that feature?

Yes, you'd need an external crossover, or amps that have crossovers built in to them. But I've never really been a fan of amp-mounted crossovers...

yup sure is. there are amps with built in crossovers and there are external crossovers that can be used. it's much simpler when it's right in front of you though right in the HU.

EDIT: beat me to it!

how much do those normally cost external crossovers?

why is that? just curious.

Usually they're limited in the slope, and the crossover point itself...better than a fixed passive for sure, but unless you happen to get very lucky you're not going to be able to dial in exactly what your setup needs.

$50-200ish, depending on what you want done...

ok makes sense.

10 replies, and not one helpful answer. completely threadjacked. Look, i said i would go active later, but i just want to mess around with a couple of inexpensive setups for fun.

I the HP xover point would be lowered if you had a passive for a 4ohm tweeter but using a 8ohm tweeter instead //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
