A mounting bracket system for mounting a loudspeaker monitor onto a microphone stand pole without requiring disassembly of either the loudspeaker monitor or the microphone stand. First and second mounting brackets may be mounted to a loudspeaker monitor or other product to be mounted. An indent on each mounting bracket is configured to engage a microphone stand or another elongated, pole-like structure, supporting the weight of the loudspeaker monitor through frictional forces.
