I have a pair of phonic s710 speakers and I've noticed that at medium volumes or with a lot of bass the tweeters make an awful noise. I can't really explain what the noise sounds like, but its high pitched and hurts yours ears. Kind of like a clicking noise. I haven.t been able to turn them up very loud in fear that this noise is a sign that the speaker may become damaged due to the volume. I'm running them well below their rated wattage though. i think that it might have something to do with the fact that it has no crossover and the tweeter can't take as many watts as it is rated (80 w rms)
Any thoughts or suggestions are appreciated.
