FREQUENCY RESPONSE [DIFF]^5


COMMENTS:

Appalling frequency respose, no bass! Suspect this is 91-143 sold as having speech-only response, though it was supplied as a 91-142 sold as 'truly flat response'!

Tested by comparison with Lindos MM3 mic (blue trace) at 100mm from 3" source.


Noise results are not valid (noise from power amp limiting noies floor). Actual noise is around -60dB (40dB SPL 468-wtd)
