- 24-watt RMS power handling for high output
Dayton Audios 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 exciters 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, allow for more input power for higher output applications while maintaining a slim-line form factor.
To ensure maximum acoustic energy transfer between the transducer and the surface to which it is attached, 3M VHB (Very High Bond) adhesive is pre-applied... just peel and stick! For permanent inverted mounting (or when mounting on moving surfaces), four screw tabs are also provided to support the weight of the exciter. Two PCB solder points keep installation and wiring as compact as possible.
Note: An exciters frequency response and sensitivity are completely dependent on the exciters designated surface. Thinner, smaller materials will tend to be louder and create a mid/tweeter response. Thicker, larger materials (with multiple exciters) will be slightly quieter but result in a more full-range sound.

Note: Speakers with a burned voice coil are not returnable for exchange, repair, or refund credit, as this is not covered by its warranty.
