• 4 ohms impedance for use with small, Class D amplifiers

Product Description

Dayton Audio’s 9 mm DAEX9CT-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 extremely 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. Its 4-ohm nominal impedance facilitates the use of series and series-parallel wired arrays for a highly focused, minimum dispersion sound pattern.

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. Two PCB solder points keep installation and wiring as compact as possible.

Note: An exciter’s frequency response and sensitivity are completely dependent on the exciter’s designated surface. Thicker, larger materials (with multiple exciters) will be slightly quieter but result in a more full-range sound. Thinner, smaller materials will tend to be louder and create a mid/tweeter response.
