Rare-earth neodymium motor and a proprietary voice coil
4-ohm impedance for use with small, Class D amplifiers
24 watt RMS power handling for high output
Dayton Audio's 25 mm DAEX25FHE-4 coin type exciter features the same ability to turn nearly any surface into a speaker, as other exciters and tactile transducers, only in a more compact package for working with smaller surfaces. This exciter's small size enables audio reproduction in places never imagined: toys, monitors, cabinet doors... even windows!
A neodymium magnet is employed to create maximum magnetic flux around the proprietary voice coil for increased sensitivity when compared to similar sized exciters. In turn, this reduces power requirements and makes it possible to use very small audio amplifiers, without sacrificing total output. The 1" voice coil, and cooling vents, allows for more input power for higher output applications while maintaining a slim-line form factor.
