Dayton Audio DAEX25SHF-4 Specification Sheet

Dayton Audios DAEX25SHF-4 steered high flux exciter can generate a force 4 times greater than most standard sound exciters. It has a specially designed neodymium motor system that imparts strong forces, on even the most rigid surface, for maximum loudness.

For use with small, Class D amplifiers, the steered high flux exciter incorporates a 4 ohm voice coil to extract maximum power. A wide frequency response is permitted due to this exciters low inductance.

Four screw holes are integrated into the exciters shell and combine with a 3M VHB (Very High Bond), permitting this exciter to be securely coupled to a wide range of materials, even upside-down mounting and attaching to moving objects. Two solder tabs offer quick, permanent wire attachment.

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: 15.7 mm (outside diameter)
