Aural Excitement
Dayton Audio's 25 mm EX25HRDS-4 IMS™ coin type exciter features the ability to turn nearly any surface into a speaker, 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.
Exclusive IMS™ Interchangeable Mounting System
With Dayton Audio's exclusive IMS™ interchangeable mounting system, you can try out many different configurations, placements, and exciters to find the best combination for your project. Each exciter comes with a threaded mounting pad that can be permanently installed anywhere. Installation is easy, simply remove the pad from the exciter assembly, mount the pad to your project with 2 screws or with the 3M Adhesive, and screw the exciter assembly back onto the pad! The non-destructive nature of the interchangeable mount allows you to A/B different exciters or swap non-functional units out in the field without risking damage to your project or exciters.
