Can anyone recommend some speakers that would work well with my Magnus Pro setup?

Looking for speakers that would fit well in my setup. My main obstacles are the fact that it’s a standing desk, and that my side monitor goes off the edge of the desk. I have my current speakers on their sides… If I place the left speaker vertically behind the monitor, it sounds awful. Speakers that are 6in tall or less should work. I also have the subwoofer in an ugly location and had to get an rca extension cable to reach the left speaker. I think ideally I would place a subwoofer next to the left leg and run all the cables up that leg. I’ve had difficulty tracking down something which should work. Speaker dimensions and cable lengths aren’t always listed.
