DAEX25SHF-4 Steered High Flux 25mm Exciter 20W
High output exciter design
Notify me when back in stock
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 exciter's low inductance.
Four screw holes are integrated into the exciter's 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 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.
Adhesive dimensions: 15.7 mm (outside diameter)
