My Mechanic's Car Audio
1st January 2004 - report written and upload
True event circle around middle 2002
Right Mid only example

It is supposed to be a mid measurement only, however the woofer's signal was forgotten to be removed therefore leaks in :) ehehehhe sorry.
Luckily the measurement is sufficient enough for this demonstration.
Notice the yellow color curve is the same as the blue, except smoothed using 1/3 octave. Notice the extreme lost of details there.
