Heir 3ai Measurements



Unlike the 4ai, channel imbalance is evident with the 3ai. I did not purposely move the right channel down on the graph. Measurement was retaken to confirm (took IEMs off, re-setup the micro and coupler, etc.)

Talk about v-shaped. Is the 4k dip in these heirs because of the crossover or a resonance?

Crossover related to a specific mid/tweet driver I think. I'm sure there are more knowledgeable people than me who can chime in.

Question for the more knowlegeable guys here; does the 3ai have the same BA driver configuration as the UM3X but with seemingly worse matching? Knowles TWFK+CI afaik.
