We play one club that is very small. We are also jammed into a corner and we have tried various ways of trying to get a good sound without blowing everyone away. My question is would it be ok to use one main along with one sub. We have a pair of the JBL JRX125's for mains and a pair of the JBL JRX118's for the subs. We have (3) Crown XTI 2000's. One for the mains, subs and monitors. Looking for thoughts/help.
