Your speakers have overlapping tweeter/mid response from 2KHz to 8 KHz so ear height will dramatically alter the presentation.
Most speakers with a steep crossover can do +/- 10 degrees from mid point between mid range and tweeter without any audible change - plenty of room if you sit back a reasonable distance.
