amp power vis a vis speaker power rating

This may seem like a stupid question but I generally have had amps with power around the middle range of a speakers power rating range - here is the question then if the top range of power for the speaker is 250 wpc, can you safely use an amp that has that same stated power or do you run the risk of damaging the drivers?

You can safely use an amp spec'd at the max power spec of the spkrs.
What you shouldn't do is max out both, amp & spkrs -- and this you;re unlikely to do because it's too loud.

An overdriven weak amp (i.e. clipping & oscillating all over the place) will cause damage to the drivers.
Maybe this will help.

If not, there are plenty of other explainations in the archives.
