Use Cases
-
Miniature speakers – like desktop monitors, portable speakers, or narrow baffle designs.
-
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.
