Product details
The speaker we use is built to turn large, thick, rigid surfaces into speakers. The 32mm voice coil is attached to a steel spider for maximum restoring power when high amounts of force are applied, making it perfect for large glass panes, furniture and surfaces that would normally withstand the effects of an exciter.
A neodymium magnet is used to create maximum magnetic flux around its own voice coil for greater sensitivity compared to similarly sized exciters. This, in turn, reduces power requirements and makes it possible to use very small Class D audio amplifiers without sacrificing overall output.
To ensure maximum acoustic energy transfer between the transducer and the surface it is attached to, 3M Very High Bond (VHB) adhesive is pre-applied to the main body ... just peel and stick! For quick electrical connection, two male quick disconnect spade terminals are built into the housing.
