I have recently bought a speaker and it says it is 20hz-20khz but i am not sure they might be lying. So i ran the test and if i turn volume up to 3rd level from my phone(and to highest level on speaker) i dont hear any statics etc but if i turn it up i hear them. Same thing happens on earphone too i ran the test file with earphone and turning it higher gives the same result. And even phones own speaker gives the same reaction. Anyway how can i be sure about my speaker's frequency?
