Toa SF-60 Specifications

CEILING MOUNT 3-WAY SPEAKER
DESCRIPTION
The TOA SF-60 3-way speaker is designed for permanent
installation in high-level professional applications. Its
trapezoidal cabinet and component design allow arrays to
simulate a single source.
The SF-60 is driven by a 2-way multi-amplifier (bi-amplified)
system, where one amp drives the low frequency transducer
and the other drives the mid/high combination. Correction
for time-offset, phase and frequency response is provided
by internal circuitry.
The SF-60 accurately reproduces transient responses in
the low frequencies, using a high-quality 12" woofer with a
large concentrated-geometry magnet. The SF-60 uses a
powerful HFD-651 compression driver for the mid/high
frequencies. Its LE Series constant directivity horn ensures
optimum performance and uniform sound dispersion. Very
high frequencies are reproduced by an HT-371 super
tweeter that handles only frequencies over 10kHz, for
precise sonic tracking. TOA's SW-38UL or SW-46UL2 ultra-
linear superwoofers can be used with the SF-60 for high-
level extremely low frequency response.
Sixteen T-nut holes, screw-type input terminals and
carrying handles are provided.
