I have been looking into getting this setup. Avatar B212 and a LMII head. I will be using an active 5 string. Just a few questions. What is the wattage for the 8 ohm version of the cab. I believe the 4 ohm is 1000 watts. So is the 8 ohm version 500 watts? The LMII is rated at 500 watts at 4 ohms. Should I think about getting a more powerful head since I have the head room to spare. Is the a way to get the more than 500 watts out of the LM, such as adding a power amp. I don't really think I would need more than 500 watts, but anyway. Sorry for all of the technical questions, but I am trying to learn more and more about how amps work.
