Product details
29-0J03 Spider Exciter 20W 4 Ohm
29-0J03 Spider Exciter is built with four 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). Also, the arms help to support the magnet/voice coil improving linearity when mounted on vertical surfaces.
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 allows for more input power, creating rich, dynamic sound. 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 four arms ... just peel and stick!
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.
A basic guide to creating invisible sound with exciters
Curious about how to create invisible sound with exciters? In this blog, Ben Zenker, an expert with more than 15 years of experience and 10 internationally reviewed publications, shares his in-depth knowledge on material selection, installation and optimising sound quality. An indispensable resource for the passionate DIY audio enthusiast.
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.
