Appreciate the advice fellas... Perhaps I'll consider Yammy DXR/DSR 12 inch speakers as my lowest budget point then!
Kinda want the monitor to take up as little space as possible and be wedged shaped so I can step all over it and have it pointing at my ears...!
I may may even go through the route of picking up a 3rd party stereo power amp (I have the PowerRack) and using the main outs to the power amp on to PASSIVE units (send one out to a FRFR wedge monitor in-front of me and the other out to a FRFR cabinet behind me in backline; perhaps atomic) + my guitar cabinet from the Speaker Out...!
Though then there would be nothing to send to FOH ? Unless you can use 1 main out to a stereo power amp ? and 1 to FOH ? (Could a stereo unit such as a power amp/FOH mixer split a mono signal into stereo (or 2 mono signals at least?)
