TOA SPEAKER SYSTEM
CEILING MOUNT 3-WAY SPEAKER
SF-60
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.
FEATURES
1. 3-way vented system driven by 2-way multi-amplifier
(bi-amplifier).
2. High power capacity of 120 watts continuous pink
noise for low frequency and 80 watts for mid/high
frequency.
3. 12” (30cm) woofer using a larger magnet.
4. HFD-651 type high power driver with LE Series
Constant directivity (CD) horn (90° horizontal by 40°
vertical).
5. Exponential horn tweeter.
6. Built-in passive circuit to correct time, phase and
frequency response for multi-amplifier driving.
7. Passive crossover between the driver and the tweeter
set to highest 10kHz.
8. High frequency level control for the tweeter.
9. Fixing nuts for ceiling suspension provided on top,
bottom and both sides of the enclosure.
10. The fixed baffle, the horn and the tweeter can be
turned.
11. Recessed type carrying handles provided on both
sides of the enclosure.
12. Removable punched metal front grill.
