Space inside the cabinet will be a big determining factor for what speakers will fit in your allotted space.
I will add Ascend Acoustics Luna
or Ascend Acoustics Duo V2
Both have a RAAL ribbon tweeter and are front ported. The ribbon tweeter limits vertical dispersion somewhat, so standing versus sitting will vary. The Duo will likely fill the space better, but are taller, or wider depending on how you orient them.
Best of luck.
