I currently have two Yorkville NX35's being powered by a Yamaha EMX512 powered mixer. This has been a fantastic little setup for the majority of my solo gigs. Lightweight, easy to set up, etc. I use a RCF310A as a monitor for bigger gigs.
Over the past year or so, I've been doing some bigger gigs, and I've moved up to a trio adding a second guitarist and bongo player. We've found some situations where we could have used more sound reinforcement. We've occasionally added on some Mackie Thump's that the bongo player has (which I know are not great speakers). That helps somewhat.
We had a discussion on this a while back in the solo forum. Upgrading to a bigger board is a given. I'd like to get a 12 or 16 channel board board. I was at that time discussing upgrading my cabs to powered mains, then adding a powered sub.
Through the conversation, it was noted that even though the Yamaha head touts big power (500w per side), that it probably is not adequately powering those mains. At the ohm load I'm using, and the fact that the 500w is a peak number, the guess is that it's probably only sending 90-ish watts to each speaker.
So, I'm wondering now if it would be a better starting point to simply get a new board and a power amp that's well matched to the speakers, thinking that move alone would be a great improvement, and much more cost effective than going with powered mains.. A crossover and a powered sub would come next.
First, I ask if that is sound logic? Second, I wonder what amp would be an adequate amount of power for those mains. I believe they are rated 350 watts program.
Thanks for the help!
