A significant issue here is going to be your room. It’s going to be tonally bright unless you get into some room treatment, rugs, etc. Honestly you are going to be better off with speakers that control dispersion. Horns, ESL’s, and line arrays.
Better than your suggestions, given the room, Klipsch Heresy or Hsu horn loaded or Martin Logan hybrids.
- Dali - No way. They tilt the treble up, going the wrong way.
- Tekton - Well, yes but these are the wrong models. You want the tweeter array to give you a tight pattern.
- Monitor Audio and Vandersteen - Probably the best tonal balance in your room. The MA Studio Series is also going to be stellar performers in your room. The D'Appolito configuration will narrow the dispersion vertically, ignoring more of the floor and ceiling.
