Ok, so I am working on a speaker system using my Altec 811b horns, emilar compression drivers, and JBL 2226h woofers. I have been thinking for a while about what the best solution would be for amplifying these. I was originally going to use some sort of amp, and build a crossover for them. Then I got suggested the idea of using a miniDSP an bi-amping. I acquired a crown PA amp for cheap, but testing it, the fan is much too loud for home use. Im going to sell that amp. I am not sure if the best option would be to build a crossover and use a single amp, or to bi-amp it. bi-amping seems like it would be a fair amount more costly, and I am trying to figure out if it is worth it. Also, I am trying to figure out what amp/amps to use. I want the speakers to be able to get loud, for parties and such, but I suppose that wont take that much power. Looking at a calculator, I guess even a 10w amp could do 100db+ from 10ft away, so I suppose that would be good. Would bi-amping with 2 JLH hood 1969 amps be good? Or one of those for the highs and something else for the lows? Or just one of those and a passive crossover? or something else altogether? Thanks for any insight you may have.
