The Dayton Audio DAEX32QMB-4 allows you to turn almost anything with a flat surface into a speaker. 4 ohm 40 watt sound exciter improves power handling with a vented voice coil.
• Turns any rigid or flat surface into a speaker
• Extra support, provided by four arms, improving linearity
• Large 32 mm voice coil improves power handling to 40 watts RMS
• Rare-earth neodymium motor and a proprietary vented voice coil
Dayton Audio’s DAEX32QMB-4 quad arm exciter is built with four arms that extend out from the main exciter body. This allows the exciter to transfer sound to a much larger surface for lower frequency response extension (more bass). The arms help to support the magnet/voice coil improving linearity when mounted on horizontal surfaces.
A neodymium magnet is employed to create maximum magnetic flux around the proprietary voice coil for increased sensitivity when compared to other similar sized exciters. Because of this, there is a reduction in 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 which creates rich and 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.
Note: An exciter’s frequency response and sensitivity are completely dependent on the exciter’s designated surface. Thicker, larger materials (with multiple exciters) will be slightly quieter but result in a more full-range sound. Thinner, smaller materials will tend to be louder and create a mid/tweeter response.
