Using HPF with a Crossover
 

I am in the process of installing my CDT ES-620's and was curious about whether or not I should be running them full range from my amp (Phoenix Gold Ryval) or whether or not I should be running them with the HPF on.

I dunno why I have never thought of this before, maybe because I didn't run components for the longest time. I got to thinking...usually not a good thing...that the crossover of course determines what frequencies play to what speakers. If I use the HPF I may be limiting the frequencies sent to the crossover.

Any thoughts?

If you are using a sub, engage the HP filter. You will find that with the HP filter engaged you are going to gain far more output from the speakers as you are liming the low end response to them. Try it both ways to actually listen to the difference. Without the hp crossover on, yes the speakers will have more low end response but it also leaves you wide open for damaging the woofers if you set the gain incorrect or start cranking up the bass response on the deck. The hp filter is a nice check valve to keep the speakers happy.

High pass filter affects the low frequencies to the Xover (mid). The Xover controls the frequency Xover point between the mid and tweet. Yes you should use the HPF. Somewhere around 80hz.

Great, quick response to. Thanks
