Dayton Audio Interchangeable Exciters may be used in a host of DIY executions to easily add sound to an existing non-audio specific project or create a portable speaker system, the unique mounting system allows you to try out the assortment of exciters offered by Dayton Audio!

Aural Excitement

Dayton Audio's EX32U2-4 Thruster exciter is built to turn large, thick, rigid surfaces into speakers. The 32 mm voice coil is attached to a high-strength spider for maximum restoring force when large amounts of power are applied, making it perfect for large glass panes, furniture, and surfaces that would normally resist the effects of an exciter! 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.

With Dayton Audio's exclusive interchangeable mounting system, you can try out many different configurations, placements, and exciters to find the best combination for your project.
Each exciter comes with a threaded mounting pad that can be permanently installed anywhere. Installation is easy, simply remove the pad from the exciter assembly, mount the pad to your project with 2 screws or with the 3M Adhesive, and screw the exciter assembly back onto the pad! The non-destructive nature of the interchangeable mount allows you to A/B different exciters or swap non-functional units out in the field without risking damage to your project or exciters.
