I have a 1x12 wedge cabinet I'm repurposing into a guitar speaker cab. It has a jack plate with two 1/4" mono jacks. What I'd like to do is reset the jack plate in such a way that it can:
- Run directly to the onboard 12" speaker with one input cord jacked in.
- Run a signal to a second cabinet via the other 1/4" jack.
Both the wedge speaker and the satellite cabinet speaker are 8 ohms and the amp powering this can do 8- or 16-ohm output.
My first thought was to wire in a switched 1/4" jack that can either run a series circuit between both cabinets (16-ohm load to the amp output) or the wedge speaker by itself (8-ohm load to the amp output.) I'm not going for a stereo rig here; one cab will serve as a stage monitor and the satellite can be miked for FOH or serve as a second monitor elsewhere on the stage plot.
Can anyone offer advice (and possibly a simple wiring diagram) that might accomplish this?
