What is a real PA in your book?
Not the cheapest crap available. I have multiple cabs I can use. For real small gigs a pair of JBL PRX512s on stands and a presonus studiolive 16.0.2. For bigger gigs I have EAW NT59s over NTS22 subs. Bigger yet 4 PRX535s over 4 or 6QSC HPR subs. I have a studiolive 16.4.2 when I need more mixer channels.
