Speaker Driver Exciter 20W 8Ω Ø32mm
The Dayton Audio DAEX32SQ-8 is a wideband vibrator that can convert almost any solid surface into a completely invisible speaker. With its 32mm diameter coil, this exciter is able to develop a great power and offers an impressive output capacity. The square structure ensures an easy and robust mounting to support the powerful motor while maintaining excellent linearity especially for mounting on vertical surfaces.
A Neodymium magnet is used to create a strong magnetic flux around the coil and thus increase the sensitivity of the vibrator. This also reduces the need for power and therefore allows the use of small amplifiers without sacrificing output level. In addition, the voice coil supports a power of 20W RMS for a rich and dynamic reproduction. To ensure maximum energy transfer between the transducer and the surface to which it is attached, a 3M VHB (Very High Bond) adhesive is pre-applied to the structure.
The frequency response and sensitivity of a vibrator depends entirely on the surface to which it is applied. Thinner and smaller materials will tend to generate greater sound volume and create a response in the mid and high frequencies. Thicker and larger materials will be slightly quieter but will reproduce a wider frequency range (with multiple vibrators).
