Non-Audiophile Audiophile question!

Just for the record, standard OHM Walsh CLS driver configuration is NOT Omni.

But it does have carefully controlled (by design) 360 degree dispersion. Output in wall facing directions is more highly attenuated which allows for better performance in most rooms placed relatively close to walls. Omnis and bipolar designs like Magnepan require more distance to walls for best results. Of course distance from walls also negatively impacts bass levels.

So there is still really nothing else like them either in design or the sound that you hear.

all box speakers sound like boxes.

Ohm Walsh speakers do not sound like boxes. The box is only there for the full bass that is not the forte of Magnepan typically.

I had Magnepans prior to my Ohm Walsh a number of years back.
