I've read most of the threads I felt pertained to this issue but most of the discussion involved powered mains, and passive VS powered subs. The owner of the P.A. equipment wants to upgrade, we do Classic Country and some Rock, and are a low volume band with 1 electric and 1 acoustic guitar, bass and drums, but do play occasional outdoor gigs, so we need to be able to get loud as well. We have a fully racked system which is only 2-3 years old, so what are needed are new mains, maybe a sub (if the one I have doesn't work out (a passive 18" JBL (and perhaps a crossover system)). We want passive speakers and/or sub because we are going to keep the power system, but the owner is tired of rebuilding the ‘80 era's mains and wants something lighter. Here is a list of the current equipment: Mackie Onyx 16 channel mixer Power amps: Crown XTi 4000, XTi 2000 2 DBX stereo equalizers DBX 255 XL compressor Lexicon MX 200 reverb 2 BBE Sonic Maximizers Furman Power Conditioner Mains: JBL 12" 2 way SR 4722, 600 watts Any input or recommendations are appreciated.
