Speaker power handling

Use the classe and don't look back!! Dyns don't lie when they get the juice!

The three previous posters are correct. I would add only that if you hear a loud banging/clanking sound on big bass passages at high volume, the voice coil is banging against the magnet, you are going too far, and need to back off immediately.

Ok then, this makes me a bit more confident to give it a try.
Previously driving my Magnepan 3.6r's with the Classe didn't seem to be enough power.
I'm aware of too low of power and clipping resulting damaging the tweeters, and sometimes too much power melting the woofers.

I read a few online articles that were more orientated towards dj's/pro audio and thus my concern with 4 x the recommended power of my amp.

Thanks for the replies

I have had this experience with too much power, and it is terrifying.

Be advised.

You are only using 10-15 watts at your sound pressure levels. The problem you may have is bottoming out woofers at higher levels with the more powerful amp. Sometimes the smaller amp will play louder without bottoming out and the fact remains the smaller amplifier is usually better sounding.
