XCITE XT25-4 Speaker Driver Exciter 15W 4 Ohms 40Hz-19kHz
The XCITE XT25 is a vibrating speaker designed to extend the frequency response into the high frequencies, optimised up to 19kHz. It features a dual N42 neodymium magnetic circuit delivering high sensitivity, whilst its 3.0mm Xmax, combined with a linear excursion of 1.4mm, enables controlled movement, ensuring a balance between refined reproduction and dynamic capability across the entire frequency range.
Designed to complement full-range systems, it works in conjunction with low-frequency-oriented exciters, such as the XTB40, to extend the overall frequency response, whilst retaining a sound signature that is more focused on the extreme high frequencies than models such as the XT32.
