DESCRIPTION
FEATURES
TOA's TU Series Driver Units are designed to be used in
combination with TOA's TH-650 or TH-660 round horn. The
TH/TU combined speaker can be used for both indoor and
outdoor applications, as well as for background music
reproduction. The lineup includes four models rated at 30 W
(TU-630 and TU-630M) and 50 W (TU-650 and TU-650M).
The "M"-type models are designed for use in high-impedance
(70V/100V lines) systems and standard models for lowimpedance (16 Ω) systems. This wide product lineup permits
selection of the ideal speaker for most applications.
TU Series driver units 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.
High-impedance models are equipped with an input
impedance selector switch which facilitates impedance
settings without requiring disassembly. The switch is also
equipped with an OFF position to prevent speaker damage
resulting from incorrect impedance setting.
TU Series Driver Units
TH Series horns have two types of 500 mm and 600 mm in
diameter. Both types feature TOA's round shape to ensure
high speech clarity and sound quality suitable for music
reproduction.
All external hardware (screws, bolts, nuts) are made of
stainless steel, while 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 which is more shockresistant than resin.
● Both high-impedance (70V/100V lines) models and lowimpedance (16 Ω) models available.
● Two power ratings: 30 W and 50 W.
● Input impedance selector on high-impedance models
facilitates input impedance matching from the outside.
● Gray color (corresponding to RAL 7042) helps driver units
match off-white horns.
● Compliance with IP65.
TH Series Horns
● External stainless steel hardware (screws, bolts, nuts), and
powder-coated horn and bracket ensure superb
weatherproofing and corrosion-resistance.
● Shock-resistant aluminum round horn.
● Unobtrusive two-tone colors (off-white color corresponding
to RAL 9010:horn, and gray corresponding to RAL7042:
bracket) help speakers blend in with surroundings.
