  • C7 1" (25mm) High End Tweeter

Test result:

  • Test in Car & Hifi 4/2018 - Absolute top class - Score: 1.1 - Purchase value: very good - BEST PRODUCT.

Features:

  • 1-inch (25mm) corundum ceramic-coated, aluminum dome component tweeter.
  • C7 is the pinnacle of JL Audio's car speaker design, benefiting from JL's most advanced engineering tools and full commitment to precision manufacturing.
  • The C7-100ct component tweeter is designed to deliver unparalleled high frequency performance. Utilizing a corundum ceramic coated aluminum alloy diaphragm suspended over a treated silk S-roll surround, it offers spectacularly detailed high frequency reproduction with superb off-axis response. Distortion and non-linearities have been minimised by optimising the dynamic motor and suspension behaviour.
  • Passive crossovers are not included with the C7 drivers as they are designed for active systems. Instead, we recommend a high-quality tuning DSP, such as the JL Audio TwK™ 88 or D8, or a VXi amplifier with built-in DSP, with a dedicated amplifier channel for each C7 speaker in the system. Precise adjustment of equalization, delay and crossover filters ensures optimum in-car performance.
  • C7-100ct Construction Notes:
  • Dome Diaphragm: The aluminum alloy diaphragm coated with corundum ceramic has high rigidity, very low mass and excellent stability. It also helps the tweeter's dome retain its shape and perform like a true piston at higher frequencies without compromising moving mass.
  • Suspension design: The movement of the diaphragm is centered, sprung and damped by an S-roll surround of treated silk. Ferrofluid in the magnetic gap acts as a rear suspension element in this design. Both together provide optimal damping without restricting the excursion.
  • Motor Construction: The C7-100ct uses a high density magnetic circuit with a neodymium magnet and a U-Yoke motor topology.
  • It uses an underslung voice coil wound with copper clad aluminum wire on an aluminum voice coil former. The motor magnets have been precisely optimized using advanced FEA tools to reduce various order distortion and IMD/AMD.
  • Acoustic Design: The shape of the tweeter enclosure is designed to increase sensitivity in a very specific bandwidth, which helps flatten the frequency response. It also provides improved directivity control.

Design Bandwidth:

  • With 48 dB/octave filters: 3,000 Hz - 30,000 Hz.
  • With 24 dB/octave filter: 4,000 Hz - 30,000 Hz
  • With 12 dB/octave filter: 5,000 Hz - 30,000 Hz
  • Available individually, with mounting and surface mount hardware.
  • A 15μF tweeter protection capacitor is also included.
  • The performance of each C7 driver is tested and verified, then assigned a unique serial number. Register your C7 speaker online to receive a copy of its specific acoustic test report.
