ABOUT THIS MAD SYSTEMS TECHNOLOGY:

SO WHAT MAKES THE MAD SYSTEMS A9 SO EXCEPTIONAL? 

• THE MAD-1 PLANAR TRANSDUCER
• THE DRIVER IS A FULL-RANGE DEVICE THAT OPERATES FROM ~100 HZ TO 18 KHZ
  • NO CROSSOVER POINTS NEEDED IN ANY OF THE CRITICAL VOCAL AND MUSICAL BANDPASS
  • NO PHASE SHIFT AND SIGNAL ALIGNMENT ISSUES
  • NO CHANGES IN THE TONAL RESPONSE AS THE SOUND PASSES THROUGH MULTIPLE DRIVERS
    • ALL OF WHICH DEGRADES THE SONIC PERFORMANCE
• THE MAD-1 TRANSDUCER CREATES A PLANAR WAVE RATHER THAN A CONICAL WAVE
  • THE TYPE WHICH EMANATES FROM CONVENTIONAL CONE AND COMPRESSION DRIVERS
  • A PLANAR WAVE IS HIGHLY DIRECTIONAL, RADIATING AWAY FROM THE TRANSDUCER IN A NARROW BEAM
• WHEN PLANAR TRANSDUCERS ARE POSITIONED NEXT TO EACH OTHER, THEIR COMBINED ACOUSTICAL ENERGY SUMS TOGETHER PERFECTLY WITHOUT ANY COMB FILTERING RESULTING IN A VERY SMOOTH AND UNIFORM DISPERSION IN BOTH THE HORIZONTAL AND VERTICAL FIELDS.
