Graph 1 shows the frequency response of the Audio Solutions Figaro M2 as measured by Newport Test Labs. The section of the trace below 1kHz was measured in-room using pink noise, with the trace representing the average of nine measurements taken in a grid with its central point on-axis with the tweeter. The trace above 1kHz is a single measurement made one metre on-axis from the tweeter, using a gating technique that replicates the response that would be obtained if the speaker had been measured in an anechoic chamber.
You can see that the trace in Graph 1 is very linear, extending from 36Hz to 35kHz ±3dB. This
