Description

The Dayton Audio DAEX19QLP-4 4 ohm sound exciter improves power handling with a vented voice coil. You can turn almost anything with a flat surface into a speaker.

Product Highlights

• 4 ohms impedance for use with small, Class D amplifiers

• Turns any flat, rigid surface into a speaker

• Rare-earth neodymium motor and a proprietary vented voice coil

• Four arms provide extra support improving linearity

Product Description

Dayton Audio’s DAEX19QLP-4 quad arm exciter is built with four arms that extend out from the main exciter body. The arms help to support the magnet/voice coil improving linearity when mounted on horizontal surfaces. This also allows the exciter to transfer sound to a much larger surface for lower frequency response extension, meaning more bass.
This exciter uses a neodymium magnet to create maximum magnetic flux around the proprietary voice coil for an increase in sensitivity when compared to other, similar-sized exciters. This reduces power requirements and makes it possible to use very small audio amplifiers, without sacrificing total output. The 0.75″ 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 applied beforehand 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. Smaller and thinner materials will tend to be louder and create a mid/tweeter response. Larger and thicker materials (with multiple exciters) will be slightly quieter but result in a more full-range sound.
