I made the mistake (long ago) of buying speakers that aren't matched well for my Mackie 808m powered mixer, JBL Sf25. I'm trying to figure out my best move to try and get vocals to cut through more than they are now. To be clear, this isn't for a club or gigs, strictly for rehearsal, but it seems pointless to have the monstrosity of the Dual 15's when I can't even push them. I know a 12" is a better suited speaker, but I'm also trying to not spend too much, i.e. sell my JBL's for a couple hundred a piece (hopefully) and use that to buy new speakers that are suited for the Mackie. The other option I see which may be cheaper, is to buy a power amp to push the mains louder to where they need to be. Opinions on which way to go, which speakers would be a good fit?
