1.2 OCT Front System with MAB 1000
plus one omni for optimized bass pickup
FRONT
The low-frequency signal from the omni is
sent to both the left and right channels. Using
an LP 40 low-pass filter (cutoff frequency 40 Hz) and SCHOEPS omnis, the response curve
below 100 Hz becomes substantially flat.
.
David Griesinger (Lexicon) has proposed that
L and R bass signals be decorrelated by using
additional widely-spaced pressure transducers.
At low frequencies these not only increase the low-frequency pickup but also accentuate the
difference between R and L. This results in an
increased sense of spaciousness.
