Master Audio MD64Top

Two way - Woofer 12" PhasePlug + Driver 1,5" – Processed: 900 W / 133 dB pgm - 41Kgs - MD-7 & Disco Systems 



The MD-7 is one of the most impressive compact column speaker system available. The building blocks of this massive flagship are the MD-64T full-range unit and two MD-18SW subwoofers per channel. The top system has a horn loaded 12” woofer with 3” voice coil and external Neodymium magnet configuration for optimum heat exchange. The ellipsoidal waveguide (horn) for the mid/low frequency driver includes a special concentric phase plug for improved midrange reproduction and clarity, and increases system sensitivity to 104 dB.

The compression driver for the treble has a 3” pure titanium diaphragm and suspension and also works in an ellipsoidal horn. The ellipsoidal waveguide concept achieves a perfect match between transducers and the horns, and the 60° x 40° dispersion pattern allows for wide coverage configurations.



Each drive unit in the MD-64T also have thermal sensors built in, making it possible for a DPU amplifier to control the temperature of the voice coils via the SENSE system and thereby utilizing the full dynamic potential of the speakers, without the risk of distortion or damage. Furthermore, dedicated processor modules for the top systems and subwoofers (DPM) and optimize the speaker performance by means of equalization, phase alignment, sonic filters, crossovers and clip limiters.



The subwoofer MD-18SW has an advanced dual-chamber band pass design with high sensitivity, very low distortion and extreme dynamic performance. The 18¨ heavy-duty drive unit has 4” voice coil and an exclusive magnet design with Neodymium structure and DDR – Double Demodulation Rings – to flatten impedance and phase to create constant power transfer characteristics. Maximum power handling is 1600W.



The full power of a DPU-3K6 amplifier is a massive 3600 W. The MD-7 system frequency response is a very linear 30-20.000 Hz, with a maximum SPL of 135 dB.



Its wide coverage pattern of 60s x 40s, high sound pressure level and outstanding sound quality make it suitable for a wide range of applications, from big systems in live events to individual rigging in Disco applications. The low-mid way uses a 12´´ Neodymium woofer with 75mm aluminium voice coil and offers excellent heat exchange by external magnet configuration. The woofer is matched to a concentric phase plug. The high frequencies rely on a 3´´ Titanium diaphragm and suspension Neodymium driver. The low-mid and high horns have been developed following Ellipsoidal Waveguide Theory: we achieve a perfect match between the transducers and the horns. The internal crossover, divides the corresponding frequencies to each transducer with minimum losses.
