You may PREFER stereo, but you certainly don't NEED it. Many, many performers use mono systems on stage and it's just fine. In fact - 3 nights a week (weeknights) I intend to use the mono Bose system with only one woofer.
You can use the summed outputs of each kb or use a small sub-mixer to feed the Bose inputs. The latter will give you more control over levels.
The Bose controller has only TWO channels on it. The remaining 2 channels have flat EQ and just a volume control on the floor unit.
