Kitchener, Ontario (January 2008) Known for exceptional sound quality and reliability, Blackline has been featured in premium live music venues, nightclubs and installations worldwide. Martin Audio is now introducing Blackline+, which features significant improvements to provide a higher level of performance. Drivers and crossover networks have been redesigned so that all of the low frequency drivers in two-way systems now feature aluminium demodulating rings to minimize the variation in voice coil inductance as the coil moves in the gap.
The result is improved midrange clarity and reduced intermodulation distortion at high excursions, ensuring that the sound balance and quality are maintained even at high levels.
In the development of Blackline+, special attention has also been given to matching the directivity of the low frequency drivers to the HF horns in the crossover region. This has been achieved by the careful choice of LF cone profiles, together with improvements in crossover design.
The new design ethos for Blackline+ has been applied to eight full range cabinets and four complimentary sub-bass enclosures, which will begin shipping in March 2008.
