Sorry- another gear question

I'm pretty sure I'm gonna go with the GK 400RB 2x10 combo and pair it up with another cabinet. My question is, would paring the 280 watt head with the 150 watt internal speakers and an additional 400 watt 4x10 cabinet be inefficient for the 4x10 since it will not recieve near as much power as it is rated for? I've heard speakers sound better when they are driven hard. Should I go for an extension cabinet with less rated power? Say 200 or 300 watts???

One other thing-
The 400RB by itself is 150 watts to its internal speakers. Using it without an extension, would I really notice any difference in volume from my current 125 watt backline 115?

1/ Speaker power ratings. The 400 watts of the extension cab that you mentioned, is the RMS power ( Root Mean Square, means similar to "average" I think ) that the speakers should safely be able to handle without overheating damage. That doesn't mean that you have to put that much power into them in order to have them working properly. If they are reasonably efficient speakers, they should give you good tone and volume without distortion. I used a 250 watt Labsystems amp ( Similar to GK 400 RB ) into an 8 Ohm 400 watt 4x10 Genz-Benz and an 8 Ohm 400 watt 1x15" EV for years without any problems at all. Great sound and plenty of volume. If you go with that amp, try it through a few different extension cab combinations before you commit to anything, and see what you think sounds right.

The 400RB is a superior amp. It might not be that much louder in your given scenario, but I daresay it would be a lot punchier and have a better tone. :)

I have the RBH series 2x10 combo. It is the one that comes with the 1001 head. I want to keep the head, but I will sell the cab to you if you want it. It's in mint condition. Pick any of the RBH heads and load it in there. That way, if you don't want to take along the 4x10, you have a killer combo on wheels. You will get more speaker for the money that way.
