Tweeter Technology
Tweeter technology describes how a speaker’s treble driver produces sound.
Dynamic uses a voice coil to move a dome or cone; fabric and metal domes can both be Dynamic. Electrostatic moves charged film between electrodes using electric forces.
Planar magnetic uses conductors on film in a magnetic field. Ribbon uses a metal strip that itself carries current. AMT (Air Motion Transformer) squeezes air between diaphragm folds.
Compression drivers feed their diaphragm’s sound through a small outlet, usually into a horn. Bending wave uses a flexing diaphragm.
Tweeter Technology — Loudspeaker
These catalogue groups can overlap physically: compression drivers commonly use voice coils too.
Tweeter Technology is not applicable to an ordinary full-range single-driver speaker without a separate tweeter. For a panel spanning midrange and treble, record its technology under Tweeter Technology and Midrange Technology. Separately sold super tweeters are excluded.
No type guarantees better sound. Compare the complete speaker’s frequency response and sound spread, which affects where you hear the treble.
