The Blackline H3T
+
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 H3T
+
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
H3T
+
features a neodymium 1” (25mm) exit compression driver with a
Kapton diaphragm for high sensitivity and extended HF performance.
When driven in bi-amp mode, a Martin Audio M3
+
Electronic Controller
is available to provide H3T
+
crossover and limiter facilities. A DX1 or
equivalent controller is recommended for provision of crossover and
limiter functions in tri-amp mode.
