The XCITE XBS100-4 is a vibrating speaker designed to convert an audio signal into mechanical vibrations that are transmitted directly to a surface. It delivers 500W under 4 ohms, utilising an FEA-optimised, low-mass neodymium magnetic circuit and a dual 11.4cm voice coil to ensure rapid and controlled movement of the inertial mass.
The XBS100-4 features a lightweight neodymium magnetic circuit, which has been optimised using FEA simulation to refine the magnetic flux distribution, thereby improving responsiveness whilst minimising energy loss. This approach is further enhanced by the integration of a dual 11.4cm voice coil, allowing for increased excursion capacity whilst maintaining precise control over movement.
The system is built around a dual steel suspension system, which stabilises the movement of the inertial mass whilst limiting mechanical distortion under heavy load, thereby ensuring consistent sound reproduction even at high power levels. This design enables the system to deliver 500W of power under 4 ohms.
