Sir ano amp mo ilang channel? are you using 2 amp system?

Medyo delicado kung mali ang set points ng frequency cutoff mo sa each speaker then you play it loud. But I assume naka passive setup ka meaning you use the crossover nung separates then you are safe.

Just basic understanding sir, say tweeter it can handle only high frequency signals 3.5Khz up.

Mids depends on the speaker brand but usually can handle 60Hz to 4Khz

Sub can handle as low as 30Hz to 63Hz to some they over lap it to 80Hz.

First step in tuning sir ay level matching I hope na level match na yang system mo.
