TOA SPEAKER SYSTEM

CONSTANT DIRECTIVITY HORN

LE-M124/LE-M94/LE-M64/LE-M42

DESCRIPTION

The LE Series constant directivity horns employ original
TOA technology to meet stringent professional standards
that always call for precise directivity control, high
efficiency and excellent sound quality. They are ideally
suited for such applications as theaters, concert halls,
auditoriums, movie houses and churches.
The TOA LE Series constant directivity horns employ
different formulas to optimize the horizontal and vertical
side wall contours. Also, both side walls are so arranged
as to allow the mouth to most closely approach an
equiphase surface. These factors combine to make the
horns geometry ideal for maintaining uniform directivity
over the rated frequency range.

Each horn has a crossover point of 500Hz and above
when used as part of an HFD-260 system, or 800Hz and
higher with the HFD-220 system. Frequency response is
uniform over the full frequency range from 800Hz to 16kHz
at any point (2kHz to 20kHz vertically) within the rated
coverage angle.
controlled coverage angle of: LE-M124: 120 x 40 degrees;
LE-M94: 90 x 40 degrees; LE-M64: 60 x 40 degrees, and
LE-M42: 40 x 20 degrees.

The horns have a horizontal by vertical

Each LE Series horn comes with a 2 in. (49mm) throat
diameter for mating with a TOA HFD-280-8/16 or HFD-

220-8/16 high-frequency compression driver. Horn
construction is of solid polyurethane of sufficient thickness
to suppress resonance.
