Figure 5. The curves above left show the effect of the 'bass tilt', 'bass
level' and 'bass roll-off' controls on the free field response. The curves
to the right show the effect of the treble and midrange 'level' controls.

Note! All frequency response curves were measured in a cali-
810 mm (32")
brated, 12 m cube, anechoic chamber at 1 m using grade 1
measuring equipment. Input signal levels were set at -20 dBu.
The anechoic chamber error in the free field response is less than
0.5 dB down to 60 Hz.
