Description
The Dayton Audio TD20F-4 uses a 3/4" silk dome to produce smooth response with excellent dispersion. At only 2-1/2" diameter and just over 1/2" deep, this tweeter is ideal for use in any compact design.
Dayton Audio's TD20F-4 3/4" silk dome tweeter incorporates an optimised diaphragm that combines low mass, superb damping, and a carefully calculated dome profile offering an exceptionally flat frequency response. This along with the low distortion neodymium motor system ensure that high frequency content is reproduced as transparently as possible.
Features
- 3/4" Silk dome provides articulate yet non-fatiguing high frequency reproduction
- Exceptionally flat and smooth frequency response
- Ferrofluid for improved power handling and damping
- Neodymium magnet low-distortion motor system
