The short answer to you question is no, so long as you are not trying to drive your pair of speakers beyond their limits. In most cases having not enough power is the cause of speaker failure. What happens is people start trying to get volume levels out of weaker amps and they drive the amp into clipping. Clipping cause the amp to distort and that is when you start blowing tweeters. I have repaired hundreds of speakers and in most every case the person was using a low power/low quality amp. Only once did I have a case of too much power causing a failure. The guy was was using some huge sound reinforcement amps and had about 2500 watts per channel. When you have an amp that is 300, 400, 500 watts just don't drive the speakers beyond their level, when you hear the woofer coil banging you have surpassed it. With a set of paradigm towers you would be at ear bleeding levels by that time. I would not worry about a carver amp though, the ones I have listened to in the past have not had any balls at all. Remember this when you decide on an amp. If you have a good 50 watt amp and you think you need more volume, you would have to increase the amp by a power of 10 to get double the volume level. Meaning you would need a 500 watt amp to double the volume level of a 50. If your 50 watt amp plays at 95db's in order to achieve 105db's which you would percieve as twice as loud, you would need 500 watts for the 10db's more. An increase in 10db's is perceived as 2x as loud by the human ear.
