Dayton Audio DAEX32U-4 Specification SheetBuying Options
Dayton Audios DAEX32U-4 Ultra exciter is built to turn large, thick, rigid surfaces into speakers. The 32 mm voice coil makes it perfect for large glass panes, furniture, and surfaces that would normally resist the effects of an exciter.
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 Class D audio amplifiers, without sacrificing total output.
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 to the main body... just peel and stick! Two male spade quick-disconnect terminals are built onto the main body for quick electrical connection.
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.
Dimensions: 2.625" (66 mm) overall diameter x 0.75" (19 mm) total height • Adhesive dimensions: 1.64" (41.7 mm) outside diameter, 0.86" (21.7 mm) inside diameter
