Contour Enthusiasts Group Archives Forums Modifications Audio Crossover Settings

I just installed my JBL P80.4 and it is powering my Infinity Kappa's.

Now, i have no clue how to set crossovers.

They are labeled as follows

X-Over
x\ x \ x \ x
4v 250mv \ 32hz 320 hz \ 32hz 320hz \ 4v 250mv

As far as i can tell, the first and last ones control something like gain. It makes the front or the back louder.

The manual says that
The electronic crossover can be selected as a 12dB/oct High Pass Filter [HPF], 12dB/oct low-pass filter [LPF] or it can be defeated [flat]. The crossover frequency can be set at any frequency between 32hz and 320hz.

What do i set them at? Help!

Edit for clarity

Do you have a sub woofer? If you don't then just set the x-over to flat or defeat.

If you do have a sub then you'll have to do some tweaking to get the best sound that suites your taste. Usually 90-120Hz is good.

I know the Kappas don't have that good of bass response so if you do have a sub then go with a little higher x-over like 110Hz.

I'm going with Kappa components up front.

Hope that helps.

No subwoofer yet. I am getting one soon. Thanks for the reply.

Do you have new kappa's, the silver ones? They won't produce lot of bass, but they do sound good, and make good use of a little power with clear highs and strong mids. I would run the crossover even without a sub, but set it pretty low. They just won't produce any worthwhile sound below a certain frequency, only distortion. AND I HATE DISTORTION.

fly since they have passive crossovers, u can set the amp to flat to not use the amp's crossovers

I got the brand new ones. Kappa 692.5CS if I remember correctly. I know that the Kappas don't make a lot of bass so thats way I'm going to be going with some 6x9's in the rear to make the bass.

Can't wait to get them installed!!
