These are not passive but will work better than your choices from my experience.
AudioengineUSA or some KEF. Not best in any way but putting speakers on a desk is a terrible way to listen. I have tried many speakers on the desk.
I have bought a few of these in the past and it does the job of hearing music on a desk.
I am selling my office system and buying going with headphones for my office (losing the office space). However, when I was using my Magnepan LRS+ speakers in my small office, I had the speaker behind me and the sound was unobstructed to my ears. It was pretty amazing.
My headphones are significantly better than the LRS+ or most small speakers that were unobstructed to my ears. Though, headphones really do not give you great freedom to move around. So, it is a compromise of me.
