Blackline Series has set the standard for portable, professional loudspeaker systems. Blackline systems are synonymous with exceptional sound quality and reliability and have become the benchmark for premium live music venues, nightclubs and installations worldwide. Martin Brother engineers have now incorporated significant improvements throughout the range to take the Blackline Series to a new level of performance. Drivers and crossover networks have been improved and all low frequency drivers used in two-way systems now benefit from the addition of aluminium demodulating rings to minimise 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 is maintained even at high levels.
