German Maestro MS 64.3 M-Line - 3-Wege Composystem

Tweeter
UltraSphere technology for extraordinary wide sound irradiation
Nano-ceramic coating on the tweeter dome for minimizing reflections at high frequencies
FEM calculated tweeter dome geometry for best possible force transmission from the voice coil to the tweeter dome
High power neodymium magnet system for best efficiency
0,75mm² connection cable for a lossless connection
The MT 40 WS with UltraSphere technology is a very high-resolution tweeter and one important component of the M-Line.

Crossover
Optimized circuit layout for minimizing interferences between the used build parts
Open enclosure design for perfect heat allocation during the use of the system
High-end film capacitors,electrolytic capacitors and coils to keep the crossover acoustical completely neutral
Adjustable tweeter and midrange volume level 
for keeping a perfect tonal balance in different installation scenarios
The M-Line crossovers have been engineered for fitting together all components of the M-Line 2-way or 3-way systems in the best possible way.

Midrange & Woofer Drivers
Nano-ceramic coating to minimize distortions and support the membranes
FEM calculated membranes for a high-end linear frequency response
25mm / 38mm edge wound voice coils for a high power handling
Gold coated connection terminals for an optimum connection to the speaker cable
Compact, high efficiency neodymium magnet system with FEM calculated t-yoke geometry to increase efficiency and linear travel of the voice coil
Aluminum basket with CTC technology for optimum heat removal and best performance
The MM 4008 midrange driver and the MW 6508 woofer driver are using nano-ceramic coated polypropylene membranes with an optimized geometry.
