A few notes...
First, efficiency of 93 db is a moderate efficiency. Its likely though that these speakers are really rated by sensitivity instead of efficiency, if so then the actual efficiency if the speaker is 4 ohms will be 90 db. I just noticed the tis49 stated exactly the same thing above.
In the average size room 200 watts will be nice to avoid clipping when 'rocking out' but it will be right on the edge. I had speakers of 89 db 1 watt/1 meter and I found 200 watts to be barely enough power if I was pushing things.
Let's talk about 'current' for a moment- there seems to be the usual confusion about what that means on this thread (based on the use of the phrase 'high current') so let's go through the math:
Assuming 300 watts from the amp and a 4 ohm load, the power formula tells us that the current really isn't all that high:
Power = Current squared x load impedance
300 = Current squared x 4, solving for current we get 8.66 amps.
The thing to note here is that it makes no difference the technology of the amplifier, if it can make 300 watts into 4 ohms then the current will be 8.66 amps. If 8.66 amps does not seem like a lot to you, then we have the germ of a conversation you might want to have.
