Fix Crackling on Behringer Eurolive B115D
Audio Equipment: Is the loud popping sound when you plug/unplug your speakers bad for them?
Most speaker cones are driven from a power amplifier.. The pop - like you said - is a transient spike. But the important thing here is that it gets amplified up through the pre-amp and into the power amp.. Speakers usually move in the ol' in-out fashion with respect the the voltage at the input.. and a big spike could loosen the cone from its suspension mechanism.. The higher the power and the more delicate the cone - the more the danger to the speakers ( what is normal for a woofer cone, could end blowing up a tweeter cone) . For e.g. In live events, where high output PA speakers are used, this is a very serious issue - because such a spike could throw the speaker cone out of its place, and it wouldn't work from that point on. For this reason, some high end audio equipment have a limiter at the output, that prevents signal from exceeding a certain predefined limit. So any occuring transients would never hit the cone at a level that is unhealthy to them.
Most home audio equipment tends to operate at lower levels. That being said, there is still some damage inflicted on the speakers - just maybe not of the same magnitude.. especially the smaller ones.
If your system has a remote control, it might be wise to hit a mute button just before you change to another input... or maybe find a way to turn off just the speakers (if separately powered) before you interchange the connection
What did a blown fuse sound like. How did you know the fuse blew? Ive had mine for three years and the tweeter stopped playing any music at all and all the sound came out of the woofer. does this sound like your problem?
