Didn't we already answer this.i have the below amp
View attachment 40699
its powering 4 pioneer speaker model 1675v2 which runs within 35 Hz to 20 kHz. ive set HPF on the amp. so, where should i set the frequency knob?
80-100 is normal if 80hz makes them sound bad start going up
There is a reason that amp has 80 and 125hz marked it's common crossover points
Every speaker plays different in different environments. This is why install is so much more important than the cost of the speaker.
