Image Graph of Audio signal

These two spectrographs demonstrate the results of Mackie’s acoustic correction processing. Frequency is represented on the Y-axis and time on the X-axis. Colors indicate amplitude, with red being loudest and green being softest. A quick, full-spectrum burst of noise is delivered to the loudspeaker, and its’ response is captured over several milliseconds. Comparing the two graphs, you can clearly see that the HD Series loudspeaker is free from the extra reflections and resonances, and the overall response is more defined.  The experience is amazing clarity and accuracy, superior stereo imaging and, as we like to call it, High-Definition Live Sound.
