Choose Dayton Audio's DAEX25FHE-4 sound exciter to add dynamic sound to almost any object or surface!
Dayton Audio DAEX25FHE-4 Framed High Efficiency 25mm Exciter 24W 4 Ohm
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 2.54cm voice coil, and cooling vents, allows 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.
A great field of application for this exciter is so-called DML or flat-panel speakers. DML stands for Distributed Mode Loudspeakers and is a term for speakers that catch the eye with their incredibly slim design.
Note: An exciter's frequency response and sensitivity are completely dependent on the exciter's 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.
Curious about how to create invisible sound with exciters? In this blog, Ben Zenker, an expert with more than 15 years of experience and 10 internationally reviewed publications, shares his in-depth knowledge on material selection, installation and optimising sound quality. An indispensable resource for the passionate DIY audio enthusiast.

Excellent value for money exciter. Using four connected in series-parallel per 500x330x25mm high density EPS plate, and get very clear and loud sound. Can get to unbearable levels, and had them running it really loud with a 90Hz HPF for a few tracks and they didn't event get warm to the touch.

Very nice exciter. Work smoothly on a ceiling tile. However, the sticking system is not very convenient as it is very hard to separate it from the protective beans.
