Quantum Series QT1.0

Quick Specs

  • Tweeter for Car Hi-Fi
  • Precision-coated textile diaphragm
  • Copper-clad aluminum voice coil wire
  • Dual neodymium magnet
  • Black anodized magnet structure

Quantum Series 1.0 is a high performance 30mm soft dome tweeter.It uses a light high-stability ferro fluid. Low resonance frequency and high power handing,low distortion and the smooth and extended frequency response combine extreme details makes it work equally well for most demanding high frequency car audio applications.


1. Precision-coated textile diaphragm for improved consistency and high-frequency extension
2. Vented voice coil former for reduced distortion and compression
3. Copper-clad aluminum voice coil wire offering lower moving mass for improved efficiency and transient response
4. Build-in cavities under dome/edge to equalize pressure for lower distortion and lower resonance frequency
5. Rear heat sink for increased power handling and reduced power compression
6. Dual neodymium magnets for improved efficiency and improved magnetic shielding for A/V applications
7. Flexible lead wires for higher power handling and larger excursion
8. Black anodized magnet structure for increased power handling and reduced power compression
9. Gold plated terminals to prevent oxidation for long-term reliable connection
