Z-Line Speakers

Z-Line Speakers

  • Composite basket w/original German-spec material
  • 30mm ceramic coated titanium dome tweeter
  • Tweeter features nylon surround for lower fs
  • Mica-filled PP cone mated to UV butyl surround
  • 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 #: ZC1-216 | SKU: 806576224617 | Category: Z-Line Speakers


    • Ceramic Coated 1.4” (38mm) Titanium Dome Tweeter
      Ceramic coating helps to reduce over tones and harmonic distortions that can occur when using Titanium at higher power levels. The unique tweeter assures the system is producing the highest sound quality with the lowest distortions.
    • 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.  

    • Nylon Surround
      The Z-Line tweeters are mated to a Nylon Surround which dramatically reduces the Fs specification. Subsequently, you will hear very smooth high frequencies, even when pushing the system hard. 
    • Oversized thermal formed cone
      The injection molded Polypropylene Cone delivers impactful midrange/midbass and is perfectly matched to the Butyl Rubber Surround for great sound.
    • Under mounted UV butyl surround
      Mounting the surround on the backside of the cone improves strength.  Flexible piston action UV protected rubber which will be impervious to temperature swings of very warm and very cold.   

    • PA66 composite Baskets with Glass Fiber reinforcement
      PA66 is a composite cast material designed to be used in future orbital spacecraft. Its purpose is incredible strength but lightweight. PA66 is what NASA uses to eliminate metal parts with composites.  

      PA66 is far more temperature and chemical resistant than standard plastics or ABS. This is important when developing low midrange and bass frequencies in a small diameter driver.  Reduce the flex in the frame and you tighten the sound by eliminating weak points in the mounting system.  

    • ABS Gasket
      Strong ABS plastic is used to seal the mounting  between the speaker frame and the vehicle  
    • Tinsel Leads Silicone Jacket
      Silicone jacketed, extra flexible leads for strength and durability  
    • Voice Coil Former
      Aluminum - Lightweight aluminum former which helps voice coil dissipate heat
    • Bumped Design Cotton Spider
      Adhesive impregnated cotton spider with bumped design which allows for more clearance and longer excursion  
    • Crossover Design 
      12db high-pass / low pass crossover on components. High end capacitors and resistors create a smooth transition between midbass tones from the woofer/midbass and midrange tone with higher frequencies handled by the tweeter.  These crossover points make critical frequencies seamless and distrotion free.  
    • Spring Loaded Terminals
      All speakers utilize spring loaded connectors for positive and negative speaker wire connections. Connectors are satin finish nickel plated brass to resist rust
    • Mounting / Installation 
      Euro-DIN - Unique shaped mounting brackets and holes to accommodate OEM and custom installations for midrange
    • Tweeter Hardware
      Flush and Surface hardware Included
