Description
A 1½" mini speaker from Dayton Audio's Commercial Engineering (CE) Series, with a light Mylar diaphragm, a neodymium magnet and an injection-moulded plastic frame that can be press-fitted or glued in place. It suits headphones, portable electronics, kiosks, intercoms and electronic games, and the 8 Ω load works with most small amplifiers. Dayton notes the diaphragm is fragile, so mount it behind a grille.
Features
- Lightweight Mylar diaphragm
- Rugged moulded plastic frame
- Powerful neodymium magnet
- Light weight
