Dayton Audio CE38MB-32 Specification SheetBuying Options
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.
Featuring a smooth-sounding and feather-light Mylar diaphragm and high 32 ohm impedance, the CE38MB-32 driver is the perfect replacement driver for headphones. The 32 ohm impedance makes it an easy load for the integrated headphone amplifier in most portable music devices and phones, while the 38mm frame replaces most 40mm nominal size headphone drivers. It’s also a great fit for other low-power mini speaker applications, such as electronic toys, speakerphones, and intercoms.
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.
