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. Cooling holes placed strategically on this exciters housing allows for higher power handling, for applications where more output is desired, while maintaining a small 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! 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.
