I own the Alpine SPX-177r component set.
I broke a tweeter.. being stupid.
I need to replace the tweeters.
In order to do that, I need to know what the set crosses over at.. correct?
I cannot find this information.
I need help.
Thanks.

 

try page 23 of your manual.

hey thanks a lot.. I lost my manual, and couldn't find it online..
looks like I'l be using a cross of 2350hz
I can now look into buying some Vifa's

 

You should be able to install any tweeter it will be xovered the same if you are using the same crossover.

 

Only if the impedance of the new tweeter is the same as the old.
