      Product details

      Dayton Audio DAEX25VT-4 Vented 25mm Exciter 20W 4 Ohm

       

      Dayton Audio's 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 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.

       

      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.

       

      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.

      After reading mixed opinion on the sound quality of exciters I decided to give these a go, and I'm glad I did! I've mounted them to tile backing board (the cement/foam sandwich type, 10mm thick) and am using them as the rear L/R in a home theater setup which can be built into the wall and easily plastered over as I (and moreover, the wife!) don't want visible speakers behind the sofa, and they sound great. With board size of 600mm by 400mm they produce decent bass - obviously a sub is going to help in that area for real grunt, but for general listening they are adequate. I was sceptical of the 20W output, but with boards of that size I would say they probably do manage it, or at least close to it. Voice clarity seems to suffer before music when pushed hard so if you need the full 20W maybe go with something more powerful, but for satellites it's plenty of juice for me. The small sacrifice in sound quality for 100% invisible speakers was an easy one to make!
