Look at Stereophile’s measurements for Tekton. They are pretty neutral and have good imaging, they have a huge downside though due to the design, they have garbage vertical performance. I’m sure you’ve heard electrostatics like MartinLogan having a “pin needle sweet spot”, in that you have to be perfectly cemeteries for them to sound good, Tekton is the same way except in the vertical plane, so any amount of vertical head movement (sitting upright vs slouched) is gonna change the sound by a good margin.
