Toa Driver Unit in BD:
TOA has been manufacturing horn speakers practically from the
company’s very beginning, over eighty years ago in 1934, and today
we are recognized even among our longstanding industry
contemporaries as a veteran of highest expertise in this field. By
1949 we had succeeded in developing Japan’s first reflex-type horn
speaker. We have always dedicated ourselves to being “an
international company contributing to human society through sound
and communication,” valuing above all the physical craftsmanship
that allows the delivery of the clearest possible sound information to
listeners. In 1962, an inquiry from abroad led us to conduct
transmission testing on an ultra-large PA system. This system, which
used a 6.6-meter horn and a 4kW transistor amplifier, marked a
transmission distance of 12 kilometers. This achievement would
prove instrumental in laying out our destiny of long-running
involvement in outdoor public address systems.
TOA-developed horn speakers were often painted blue, and they
would become widely familiar as “blue trumpets” unique to TOA. In
Indonesia, where we established both factory and sales facilities in
1976, TOA horn speakers became such a part of the public
landscape that they were often referred to as “Toas.” They are still a
conspicuous part of everyday life there, most notably for public
address among the country’s many mosques.
Even today, horn speakers represent one of the fundamental shapes
of public address speakers, offering a simple PA system that remains
more indispensable than ever in delivering public announcements.
In Japan, too, where natural disasters are frequent, horn speakers are
an essential component in the outdoor emergency notification systems
used for broadcasting evacuation instructions and other vital
information. Naturally, the demand for the clearest possible outdoor
broadcasting sound is strong in this market.
In 2011, the Great Tohoku Earthquake caused a massive tsunami that
devastated a great number of Japanese coastal towns and villages,
taking the lives of many who were unable to escape in time. As this
disaster unfolded, the sheer number
of outdoor speakers calling out
evacuation instructions caused
pronounced sound overlaps that made
their announcements difficult to hear.
And in many cases, the speakers were
simply swept away by the rushing
waters. Reflecting on these systemic
flaws, TOA has been developing longrange speakers capable of delivering
clear announcements with fewer
speakers over longer distances, and
we have been testing these repeatedly
in metropolitan environments to
continue deepening our expertise in
outdoor sound broadcasting and
reinforcement.

The TOA TU-651 loudspeaker horn driver unit. Ideal for public address announcement applications and ice cream van music reproduction. With this 50w horn you’ll certainly hear the announcement or ice cream van even at the furthest distances, unfortunately so will the kids so get ready to put your hand in your pocket or tell them a little fib!
Driver unit needs to be used with a suitable horn but is compatible with other horn units too, for example we know it fits vintage Clarion horns used in many of the lovely ice cream vans that grace our streets in the summer.
The powder-coated driver also has stainless steel screws to ensure the weatherproof capability of the unit.

TOA TU-630 Driver in BD:
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 30W (TU-630 and TU-630M) and 50W (TU-650 and TU-650M). The “M”-type models are designed for use in high-impedance (70V / 100V lines) systems and standard models for low impedance (16Ω) 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. TH Series horns have two types; 500mm and 600mm 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 shock resistant than resin.
