1. Most speaker systems require rather heavy boost at
the lowest frequencies due to the large amount of air
that must be moved. However, speaker woofer cones
resontate between
4560Hz where output is higher
so do not boost too much
at
60Hz. Use heavy boost
at
150Hz, Less boost at 400Hz.
2. Due to sound-wave reflections between the front and
rear windshields of a typical vehicle, there may be
heavy loss between
700Hz to 1.3kHz so moderate
boost here is very effective and will create more
"presence" for vocalists.
3.
The mid-range from
3
to 6kHz should not require
much change from flat (center) Most speakers work
well here. Adjust per your taste.

4. Due to limitations in human hearing. sound above
I
8kHz is not heard very well. Moderate boost at 1 kHz
adds a crisp charactr when percussion instruments
are present.
