Just a couple questions about amp tuning. I have a Cerwin Vega B52 amp along with Hertz CPX 165 Pro speakers. I tuned the sens/gain with a multimeter per the sticky on this site, then listened to a few songs and saw how they went. I had the x over mode in HP (high pass). What is flat? And also I see there is a **** called Freq. What exactly does Freq do and should I pay more attention to adjusting it?

 

 

To add to what Outkast is saying, with those speakers, you need to set the HP filter frequency to around 80 or so or around 9 oclock on the freq dial.

 

Thanks for the fast responses guys. Not to sound stupid, but for frequency I suspect 80hz would barely move the dial? Just a bit past the starting point, clockwise at the 9 o clock position? I also have it set to HP currently.

 

 

Understood, I was unclear about how to set the frequency after I set the gain. From research it appears that most are set in the 80-85Hz range, doesn't look like I will have to move the dial much. Thanks again.

 

Also remember that bass distortion will cause premature death to any speaker.

 

So the idea is to get the freq high enough to avoid low freq/bass distortion? Curious what happens if it's too high?

 

If you set your gains on HP with the Freq **** bottomed out at counterclockwise, it's likely they'll need tweaking as well. DO NOT rely on a meter for your gain settings. Always finish by ear with the bike running.

 

From what I have heard on my own system it just makes them sound "brighter". It isn't that you will be boosting the high frequencies going to your speakers as you raise the crossover **** you will be reducing the lower frequencies going to them. In this scenario I'm not aware of any harm that could result.

I am not an audiophile though nor do I play one on TV.
