Tweeter Composition Benefits

  • Military grade “A” titanium used throughout Z-Line
  • Added nano ceramic coating for extended range
  • Use of titanium originated by MBQ in the late 60’s
  • High heat tolerance handles more power
  • Greatest weight to strength ratio of any metal
  • Unmatched frequency extension – beyond 30kHz
  • Smooth response within the audible range
  • A titanium tweeter plays loud and clear when you need it to but sounds great all the time!

Basket Composite Specifications

  • Basket material blend is PA6 + 15% glass fiber
  • PA6 is a cast nylon material with higher tensile & flexural strength than steel, ABS or other plastics
  • High operating temperature capability – up to 428°
  • 15% of composition has added short glass fiber strands that further improve torsional rigidity
  • Result is a lightweight basket with extremely tight manufacturing tolerances
  • Non-conductive material doesn’t absorb magnetic energy like stamped steel resulting in a smaller, more compact speaker
