The JBL 4412 acoustic pink noise response at the listening position on the speaker axis in our control room at Greenledge Studios on May 17, 2005, after JBL left speaker was refoamed, HIGH=-1 MID=-4, with graphic equalization, measured using PRAXIS @ 1/12 octave, 65536 points. Data obtained using a calibrated Beyer MC740N Microphone set to Omni mode (green trace), and an AKG C451 EB uni-directional microphone (pink trace). Both the green and pink traces are actual, measured responses of the speakers in the room after equalization (using the different microphones described above).
