  • 12bd/octave crossovers used throughout line
  • Removable phase lens allows the tweeter to be tuned for the application

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

Features & Benefits

Part #: ZT1-25 | SKU: 806576224587 | Category: Z-Line Speakers
  • 1.4” (38mm) Ceramic Coated, Titanium Dome Tweeter
    Ceramic coating helps to reduce over tones and harmonic distortions that can occur when using Titanium at higher power levels. The assures the system is producing the highest sound quality with the lowest distortions.
  • Treated Silk Surround
    Silk reduces harsh distortions which can develop on the the surround in the transition point from the tweeter dome to frame where the surround mounts.
  • 35mm (1”) dome on a 25mm (1”) voice coil
    Creating a larger radiating area on the dome creates more output giving the tweeter a louder yet smoother sound.
  • Removable Phase Lens
    The phase lens allows “Dispersion Tuning” which permits the listener to widen or narrow the width of the soundstage depending on the chosen mounting location. When the tweeter is installed away from listeners or pointing at a windshield, a wide dispersion is better - phase lens on. When the tweeter is mounted with direct access to the listener, the phase lens off, creates a narrow soundstage with brighter high tones. Additionally the phase lens aides in reducing harsh harmonic that can develop at higher frequencies.
  • External Crossover with -12dB Per Octave Slope
    High frequency driver has a 12dB per octave slope on the output of the crossover
  • Terminal Connections
    Secure speaker wire of between crossover and tweeter
