Turns any flat, rigid surface into a speaker
Dayton Audio's DAEX32QMB-4 quad arm 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 1.25" 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!
