Dayton Audio’s DAEX25Q-4 features four extended arms for turning larger surfaces into speakers, and increase bass output. Spring-loaded speaker terminals facilitate fast electrical connection.
• Quick, secure installation with pre-applied 3M™ VHB™ adhesive
• 4 ohms impedance for use with small, Class D amplifiers
• 20 watt RMS power handling for high output
• Unique, four arm design for exciting a large surface
• Rare-earth neodymium motor and a proprietary voice coil
Dayton Audio’s DAEX25Q-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).
A neodymium magnet is employed to create maximum magnetic flux around the proprietary voice coil for increased sensitivity when compared to similar sized exciters. This reduces power requirements and makes it possible to use very small audio amplifiers, without having to sacrifice total output. The 1″ voice coil allows for more input power, creating rich, dynamic sound.
3M VHB (Very High Bond) adhesive is pre-applied to the main body, and the four arms, just peel and stick. This ensures maximum acoustic energy transfer between the transducer and the surface to which it is attached. Two spring-loaded terminals are built onto the main body for quick electrical connection.
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.
