dear all,
Recently found out that when i turn out my threshold SA3 power amp, the speaker cone will start to poping out and contracting for 3 to 4 times. Its pretty scarely seeing both my left and right speaker are expanding and contracting in different phase, the speaker cone is being pushed to the extreme as if the rubber seal as it is going to burst.
Would like to seek the advice/ explain what is the cause of this problem?
thanks in advance
