Where is 4000 hz?

[Bass911 10+ year member]

I'm using a 4 channel Hifonics amp to run only super tweeters. I'm trying to figure out on the high pass dial where 4000hz is? The tweeters are Rockford Pp4-t and the response is 4000hz-20,000hz. That is a 2 channel amp below, but the high pass is the same on the 4 channel. I'm also wondering what the slope should be? My radio has -18,-12, and -6db to choose from.

Anyone have any idea where 4000hz is on the high pass dial?

Will have to use test tones to find it. Play that frequency and put a DMM on the outputs. Roll the filter up until the voltage peaks.

Yep, tones might be necessary. You might also try starting from the fully clockwise 15k mark and going counterclockwise until you begin introducing a 4k tone. This will put you in the ballpark. From there, you can tweak it until you get a good blend with your midbass for your tastes. Level between the tweeter and midbass is obviously important.

you can do it the old fashion way where you turn the crossover up till the tweeters sound good.

I appreciate the help, but I guess I'll do it the old fashion way. I don't have a dmm, but will try the test tones. The 8" mid is supposed to play from 80hz to 5000hz.

It will play it sure. It won't play over 2k very well. Above that you won't have any dispersion and it will get raspy.

Probably between the 8 and 9 o'clock on the dial

4000hz is right after 3999hz and just before 4001hz... hope this helps

You say your radio has slopes?

Are you using an active headunit? If so set it to 18 @ 4k hz

What headunit?

You cant use your headunits slope to vary the amps crossover slope. Lol. Does the nex have network mode?
