I have had mine since 1981 - for 29 years. They are still in mint shape, and I have never had any problems. They have no overload protection, so they can be damaged if you overload them, like any other speaker. But they are not any "easier" to overload than any other speaker. I have driven them hard, but within limits, and they have never shown the slightest distortion or any hint of overload. If you are careful, they should give you no problems. You can't get speakers of this SQ today at the price you will pay for them.
