Product details

Dayton Audio DAEX25TP-4 Tripod 25mm Exciter 20W 4 Ohm

Dayton Audio’s DAEX25TP-4 tripod exciter is built with three arms that extend out from the main exciter body, which allows this exciter to transfer sound to a much larger surface for lower frequency response extension (more bass).

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 2.54cm 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 to the main body, and the three arms … 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.
