REFLEX HORN SPEAKERS

DESCRIPTION
FEATURES
TOA's TC Series Reflex Horn Speakers are designed for both
indoor and outdoor paging applications, as well as for
background music reproduction. The lineup includes four
models rated at 15W (TC-615 and TC-615M) and 30W
(TC-630 and TC-630M). The "M"-type models are designed
for use in high-impedance (70V/100V lines) systems and
standard models for low-impedance (TC-615/8Ω, TC630/16Ω) systems. This wide product lineup permits selection
of the ideal speaker for most applications.
TC Series speakers feature newly developed diaphragms
employing special heat-resistant fibers impregnated with
phenolic resin to prevent the diaphragm from absorbing
moisture and changing shape. High speaker efficiency has
also been realized by minimizing the gap produced when the
diaphragm bobbin is installed in the magnetic circuitry slit. The
aluminum foil bobbin also features excellent heat dissipation
properties to resist high power inputs and ensure high speaker
durability.
All speakers are designed to ensure high speech clarity and
sound quality suitable for music reproduction.
All external hardware (screws, bolts, nuts) are made of
stainless steel, and the mounting bracket and the horn itself
are treated with 50-micron thick powder paint coating which is
about three times thicker than that of the conventional horns.
All of these factors combine to ensure the speaker's excellent
weatherproofing and corrosion resistance. In addition, the
external horn flare is made of aluminum that is more shockresistant than resin.
High-impedance models are equipped with an input
impedance selector switch (4 steps for 100V line, and 5 steps
for 70V line) which facilitates the ease of impedance settings
without requiring disassembly. The switch is also equipped
with an OFF position to prevent speaker damage resulting
from incorrect impedance setting.
● Both high-impedance (70V/100V lines) models and lowimpedance (8Ω/15W model, 16Ω/30W model) models
available.
● Two power ratings: 15W and 30W.
● Stainless steel hardware(screws, bolts, nuts), and powdercoated horn and bracket ensure superb weatherproofing
and corrosion-resistance.
● Shock-resistant aluminum round horn.
● Panel-mounted input impedance selector on highimpedance models facilitates the ease of input impedance
matching.
● Unobtrusive two-tone colors (off-white horn corresponding
to RAL 9010 and gray driver unit corresponding to
RAL7042) helps speakers blend into surroundings.
● Compliance with IP65.
