Am I in any danger sending 300+ WPC to a speaker rated for about a buck twenty? (120rms)

Or are their other factors like efficiency etc?

Sebrof is also correct that you're very rarely sending the full rated power of your amplifier to the speakers. An EE buddy of mine told me that a rule of thumb on a reciever that shows volume in -dB is that full power is at 0dB and, I believe, half power was something like -10dB. Someone can confirm my memory, but I believe it takes twice the power to get twice the volume and double the volume is 10dB. I have CDs that I can listen to at 0dB, but very few. The majority of them I listed to below -10dB.
