FREQUENCY RESPONSE [DIFF]
Red is DPA4060 short grill
Blue is Lindos MM3.
Source is 3" driver in infinite baffle at 100mm with bass EQ (not correct). The use of a single driver allows high levels to be achieved by placing the mic very close up, as needed for testing distortion on complete sequence test. HF roll-off is the speaker.
Noise result is spoilt by the power amp noise at this range! Should be -62 (DPA) and -58dB
