  • Supertweeter – to extend high-frequency response in multi-driver setups.

  • Coaxial designs – can be integrated into midrange waveguides or custom horns.


Pros

  • Compact and easy to fit in tight designs.

  • Smooth, non-fatiguing sound thanks to the fabric dome.

  • Extended high-frequency response for sparkle and air.

  • Low distortion at moderate levels.


⚠️ Things to Consider

  • Not designed for low crossover points – best crossed above ~3.5–4 kHz.

  • Limited power handling – not for very loud systems or large rooms.

  • Works best in small speakers or as a high-end detail tweeter, not a main tweeter in large 2-ways.
