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.
