The Blackline H3H
+
is a very high performance, all-horn, three-
way system in a single, horizontally formatted, wide-bandwidth
package. 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 mid-horn of the H3H
+
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˚ HF section of the H3H
+
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.
A Martin Audio M3
+
or DX1 Electronic Controller is available to
provide H3H
+
crossover and limiter facilities.
