Tuning Mid speakers on 4 channel amp

[akuma4u]

Hey

i got an nvx 800 x4 jad amp 150 rms x 4 channels and i am running it on 4 crescendo 6.5 pro audio pwx speakers i believe they are called (they are rated for 150 rms each)

my question is relating to the tuning on the amp.

the amp has 2 LP and 2 HP buttons, when the button is depressed is x10 the frequencies when it is not pressed the frequencies remain the same.

what i have found if that when i have the HP on the amp selected and the button is NOT pressed in and have the HP around 80-100hz, there is bass/midbass from the speakers but they do not go as loud. However, when the HP button is pressed (meaning x10 is activated) and i turn the HP all the way to the beginning which i believe is 20hz, the speakers get much louder , gain can be turned up higher, but there is less bass/midbass under 200 compared to when the button is not depressed.

so my question is , should that x10 button for the HP be depressed or no?

thank you

When the press the button you are multiplying the filtered frequency by 10. So if the amp says 20-100 and you press the button it is now 200-1000. So it just depends and what you are trying to run the speakers at. You likely don't want to press the hp filter since you want mid bass going to the speaker but will want to activate the 10x for the low pass of your bandwidth.

Edited for too many 0000000

for HP it goes from 20-400hz so if that is x10 thats not 2000-10000, its 200-4000

there is noticeable less bass BUT the speakers SCREAM loud now..

can you explain what you mean by "activate the 10x for the low pass of your bandwidth"

I added an extra zero before, but I'm too lazy to look up the speakers. Are they component speakers that also have a tweeter and crossover or are they just midrange speakers? If the amp is capable of making a band pass setting you would use hp and lp filters to get the correct range you want, if running mid and tweeter on each channel you would only want to use the hp filter.

the fronts are components mid and tweeter with crossover , the rears are just mids... these are pro audio speakers. So i am using the HP filter. I hope thats right.
