We are stereo... Last I checked, most of us have 2 ears. So, our brain does a wonderful job of converting mono to stereo. The problem is when a sample is created as a stereo imagine, it sounds best reproduced in stereo.

You can have the side fill working as L&R, just L, just R, or off. So, you could have a stereo pair of these Mackies with the proper side fill selected for each side.

Once we get to hear these speakers, then we may have a different opinion. The Bose Compact and the other systems are tried and true. I still love my setup with 2 Yamaha DXR10 speakers... On the ground as monitors in stereo or on poles behind our duo.
