Ive noticed that with ultrasonic at very high volumes there is no crackling but as soon as I go down ONE notch in a certain place in the volume spectrum there is constant faint crackling. Kinda strange.
Any lower than a few notches below that is too low to hear if there is any cracking or not but there is cracking down until that point.
Mine do go up to 20khz.
Any idea why there is this crackling in the midrange volumes and not the higher ones?
Is this crackling ok or does it mean low effectiveness?
There is no crackling during the speaker test. There is a murming sound that starts up during last 5 seconds and throughout the 30 sec there is this 'up and down' sound. best way I can describe it lol. I assume thats normal..
