The Blackline H3+is a very high performance, all-horn, three-way
system in a single, 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 H3+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 H3+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 H3+crossover and limiter facilities.
