Dayton Audio CE38M-8 Specification Sheet

The Commercial Engineering (CE) series of speaker drivers from Dayton Audio provides engineers, designers, and integrators with a line of economical small drivers that fit the diverse range of applications found in consumer electronics and audio-enabled electronic projects.

The Dayton Audio CE38M-8 1-1/2” mini speaker features a feather-light and smooth-sounding Mylar diaphragm and a lightweight injection-molded plastic frame, making it great for portable electronics and headphones. The high sensitivity also enables it to be used as a speaker in kiosks, intercoms, displays, or electronic games, and the 8-ohm impedance works with most small audio amplifiers or line-level outputs. The round frame can be press-fit or glued in place.

Note: The Mylar diaphragm is very fragile. To prevent damage, avoid contact with the diaphragm when handling. This driver should be installed behind a grille.
