The F215
+
may be used with or without a system controller. For demanding applications, Martin Audio
recommends an M3
+
, DX1, DX2 or Engineer system controller configured to perform EQ and limiter
functions.
The M3
+
, DX1, DX2 or Engineer system controller may also be used to configure systems for additional
sub-bass cabinets – e.g. F215
+
+ S218
+
combinations.

3-way horn-loaded, full range systems
H3
+
and
H3T
+
The Blackline H3
+
and H3T
+
are very high performance, vertically formatted, all-horn, three-way systems in
a single, wide-bandwidth package. They differ only in drive configuration. The H3
+
is bi-amplified whilst the
H3T
+
offers user selectable bi-amplified or tri-amplified modes.
New drivers have been developed for improved performance in all bands. The Hybrid™ low frequency
section comprises a horn-loaded 15” (380mm)/4” (100mm) voice coil driver that is reflex loaded to extend
the LF output to below the natural cut-off point of the horn.
The new LF driver features a water resistant cone and triple roll surround for increased excursion.
The H3
+
/H3T
+
mid horn has a unique ‘phase-ball’ loading device which maintains the constant directivity
characteristics of the horn at the upper end of its range. It is driven by a new 10” (250mm) midrange driver
with an aluminium demodulating ring for improved high-mid clarity and reduced distortion when driven hard.
The 70° x 40° H3
+
/H3T
+
HF section features a neodymium 1” (25mm) exit compression driver with a Kapton
diaphragm for high sensitivity and extended HF performance. The internal mid/high passive crossover
allows this three-way system to be driven in a bi-amp configuration.
The H3
+
is bi-amplified and must be used with a system controller. Martin Audio M3
+
, DX1, DX2 or
Engineer system controllers may be configured to provide the recommended 2-way crossover and limiter
functions.
Martin Audio DX1, DX2 or Engineer - or series connected M3
+
system controllers - may also be used to
configure H3
+
or H3T
+
systems for additional sub-bass cabinets – e.g. H3
+
+ S218
+
combinations.
The H3T
+
can be driven like an H3
+
when in bi-amplified mode. In tri-amplified mode the H3T
+
must be used
with a Martin Audio DX1, DX2 or Engineer system controllers to provide the recommended 3-way crossover
and limiter functions.
