frequency
input terminal
Input terminal of the SF-60 is divided into Low and
Mid/High frequencies as the SF-60 is a 2-way multi-
amplifier driving system.
Be sure to connect polarities (+ , -) of each amplifier
output cord to the speaker terminals correctly.
Make the level setting according to the environmental
conditions, although almost flat frequency response is
obtainable as long as the High frequency level control is
set to NORMAL.

FREQUENCY DIVIDING NETWORK
Set each mode of the frequency dividing network as per the
following tables. Best frequency response is ensured, as time
and phase are corrected with the built-in passive circuit.

frequency range stands for a typical one
When Slope characteristics are changed,
best characteristics are obtainable by
changing phase of LOW frequency range to
normal. Decide the final change at the time
of measurement or test listening
INSTALLATION
L type metal brackets with
W3/8" nuts are provided at
four corners inside the
enclosure as shown in the
figure. Nuts are located just
at back side of the fixing
holes of the enclosure.
Utilize these fixing holes
according to the speaker
location. Refer to appearance
diagram on the fixing holes.
