If the smoke came from the left speaker, yes that's toast.
Is My System Toast?
The electricity in my town went out the other day for a short time. My wife was in the living room where my stereo system is. The amp is a Bel Canto eVO2i and a pair of Quad 12L2 speakers. She told me that when the power came back on that the left speaker crackled and smoked a little. When I looked, it had a constant low but discernible hum. I tried the speakers and they were dead. I switched the amp input to my CD player (which had been completely powered down) and there was no sound. Are the speakers and amp pretty much gone? Is it worth having the amp looked at for possible repair?

Best thing to do when you loose utility power is unplug your audio equipment from the wall outlet. Then, computers, and everything else that uses micro processors. Leave unplugged until power comes back and stabilizes. During lightning storms and high winds I wouldn’t plug things back in until the worst is over. Surge protectors protect from high voltage transients lasting not more than a few microseconds. At best a few milliseconds. Depending on how long the power is out... When the Utility power is restored it’s like a dead short on the Utility Power System. Air conditioners are all trying to start at the same time. Refrigerators are more than likely trying to start. There is a large inrush draw of current. This may first cause a voltage drop on the Utility power lines which causes more energy to be drawn. This in turn causes the voltage to rise above the normal voltage. As the load starts to level off, stabilize, the voltage will continue to overshoot the normal voltage level. Its the high over voltage event that causes the damage. The event can last several seconds or more. Well above what a whole house or point of use surge protector is designed to protect from. There are ways to protect from power outages. One way is to use over/under voltage relay(s) that will complete a circuit and energize a shut trip unit and mechanically open a (shunt trip) breaker. Downside when the breaker mechanically tripped from an under or over voltage event the breaker must be manually reset. Wouldn’t be a problem for audio equipment. This says it will disconnect the connected load from the AC wall outlet mains. Has any one with actual experience?
