For turning larger surfaces into speakers, and more bass output, Dayton Audio’s DAEX25Q-4 features four extended arms. Spring-loaded speaker terminals facilitate quick electrical connection. Highlights * Unique, four arm design for exciting a large surface * Pre-applied 3M? VHB? adhesive for quick, secure installation * Rare-earth neodymium motor and a proprietary voice coil * 4-ohm impedance for use with small, Class D amplifiers * 20 watt RMS power handling for high output Product Details Dayton Audio DAEX25Q-4 Quad Feet 25mm Exciter 20W 4 Ohm Dayton Audio’s DAEX25Q-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). 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! 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.

Marcieanne –
These drivers work great. Obviously, they will only do as well as the material they are attached too. I have 4 set up all on separate panels with 2 on each channel in series. Good clean sound, that can get fairly loud. I will note that if you want some slam with your music or movies, you will still need a sub for the lowest frequencies, but as daily drivers I have not felt the need. The biggest thing for people to get used to is that with panel speakers, you really only hear the music, rather than feel it. That can be off putting for some but i really enjoy the airiness of the sound.
