DAEX25CT-4 Coin Type 25mm Exciter 10W 4 Ohm

Quick Overview

Take your product or project to the next level by turning it into a speaker! The DAEX25CT-4 is designed by Dayton Audio with a 1" voice coil for 10 watt RMS power handling, for more output than most of the other coin-type exciters.

Product Highlights

  • Small size; just under 2" diameter, about 9/16" high
  • Pre-applied 3M™ VHB™ adhesive for quick, durable installation
  • Rare-earth neodymium motor and a proprietary voice coil
  • 4 ohms impedance for use with small, Class D amplifiers
  • 1" voice coil for 10 watt RMS power handling

Dayton Audio DAEX25CT-4 Specification Sheet

Dayton Audios 25 mm DAEX25CT-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 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! 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.

Adhesive dimensions: 27 mm (outside diameter)
