Thank you for purchasing a Martin Audio LE Series monitor. LE Series
monitors have always set the industry standard for touring and stage
applications. All LE Series monitors except the LE400C utilise differential
dispersion horn technology to define a high frequency coverage footprint
that is particularly useful for stage monitor applications.

Each Martin Audio loudspeaker is built to the highest standard and
thoroughly inspected before it leaves the factory. After unpacking the
system, examine it carefully for any signs of transit damage and inform your
dealer if any such damage is found. It is suggested that you retain the
original packaging so that the system can be repacked at a future date if
necessary. Please note that Martin Audio and its distributors cannot accept
any responsibility for damage to any returned product through the use of
non-approved packaging.

The LE12JB is a two-way active/passive switchable, multi-angled enclosure
fitted with a high sensitivity 12" (305mm) / 3" (75mm) coil driver handling
low frequencies up to the 1.3kHz crossover point. High frequencies are
reproduced by a 1.4" (35mm) exit titanium diaphragm compression driver
loaded by a proprietary differential dispersion 50˚-100˚ horizontal x 70˚
vertical horn.
The differential dispersion horn varies its horizontal dispersion from wide to
narrow as the performer moves back from the monitor. This narrowing
dispersion effectively changes the forward gain of the horn which enables
the horn to throw further, increasing the operating range of the monitor and
reducing excess spill. As the performer moves closer to the monitor the
dispersion widens giving the performer the ability to hear themselves clearly
even when positioned directly above or to the left or right of the monitor.
The multi-angled enclosure is of multi-laminate birch ply construction and is
available in left and right-handed versions. Incorporating a tough punched
