Overpowering Speakers


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?

Given a choice, I will take the bigger amp any day. You run less risk of damaging the speaker! A smaller amp, if overdriven, is how most tweeters in the world get damaged. In fact, if the tweeter is damaged in a speaker, the repair technician should always tell the user that the amplifier is under-powered.
Timlub, I'm pretty sure you will need over 400 watts to drive an 84 db speaker to 111 db.

Here's a useful web page for things like this:
