Not really "Bass" .. but maybe y'all can help anyway: In short - I'm rebuilding my small-band PA. Currently I'm setting up a new dbx PA+ to "coordinate" 2-mains (RCF 200's) with my sub (an EA VL-208) ... and I have a new set of K8's to use as side-fill/fold-back monitors. My Bass goes to a sub-mix which includes the crossover'd PA+ sub-output > QCS amp > EA Cab'. Mains are out front, Bass Cab in the back, K8's (side fills) on stands beside the main speaker stands but pointing back. What I'm trying - haven't live tested yet - is sending the same post PA+ signal to the mains and the K8's ... setting crossover / EQ / AFE for the House. The K8's will have the same signal as the mains and - at least theoretically - the stage sound will be what the audience hears - so if out-front a band-mate is way too loud (or soft) it should be apparent. I'm concerned about being able to tweak individual levels in the monitor mix - so I plan to use the AUX sends from the mixer into the second K8 channels (AUX-1 Send to the left, AUX-2 send to the right) - in this way I'll be ably to supplement the stage level - if Joe needs more of himself he can get it via .. really a "doubling" of .. that one channel (already going to the mains). Am I missing something? Is this really clever or really stupid? fwiw, it'll be only vocals and a tiny amount of guitars (supplementing on stage amps) going into the mains (no drums of bass), and the music is electro-acoustic not loud americana.
