Genesis Technologies 500 loudspeaker Measurements part 3
Fig.8 Genesis 500, vertical response family at 50", from back to front: responses 10 degrees-5 degrees above HF axis, reference response, responses 5 degrees-15 degrees below HF axis.
The Genesis's impulse response (fig.9) appears conventional, though some mid-frequency ringing can be seen after the main impulse. (The small blip just after the 7.5ms mark in this graph is the first room reflection.) The step response (fig.10) indicates that the tweeter and midrange units are both connected with the same positive acoustic polarity, but that the former leads the latter by an inconsequential 100µs or so. Again, the ringing can be seen; its period is around 1.25ms, corresponding exactly to the 800Hz frequency of the on-axis notch.
