Though my gear still hasn't all arrived, I'm constantly on the lookout for more information. I just can't stop researching, even though I've already pulled the trigger on a new rig. I've read all the manuals, and (thought) I calculated everything correctly............ But now I fear I may end up underpowering these new cabs with my PLX 1602. Avatar 210 and 212 running parallel from the 1602 at 4 ohms each cab. That only pumps 500W through each 600W cab........ Hindsight is always 20/20, as they say, but I guess I miffed up on my math. That, and I got the 1602 for a good price, figuring that it would be sufficient, but it looks as though I should have checked out the 2402 at the very least (at 700W@4ohms)...... I also realize that I've basically answered all of my own questions, but I'm sort of looking for a support thread...... Maybe I'll be OK for some gigs, but what happens if I'm just not loud enough, and I want to melt some faces???? Obviously I'll be shopping for a 2402 or more..........but I don't think that's an option right now. Just when you think you've got it all figured out......you don't.
