The XT25-4 Audio Exciter, part of the Xtreme Series, combines advanced engineering and robust design to deliver high-performance audio. Designed in Germany, this exciter is tailored for applications requiring a broad frequency range and minimal distortion for an immersive audio experience.
XT25-4 Audio Exciter – High-precision exciter ideal for audiophile and professional sound applications.
The XT25-4 Audio Exciter is meticulously crafted to achieve exceptional sound quality and reliability. With a nominal impedance of 4 Ohms and a maximum long-term power rating of 30 W, this exciter is capable of delivering powerful and accurate audio across a frequency range of 40 Hz to 19 kHz. The 2-layer, 25 mm voice coil ensures precise and consistent sound output.
Its compact design, featuring a total height of 21.5 mm and an outer diameter of 46.8 mm, makes it suitable for integration into various audio systems. The linear Xmax of ±1.4 mm provides detailed sound reproduction with reduced distortion, even at higher amplitudes. Optimized to minimize nonlinear distortions from factors like Bl(x) and Kms(x), the XT25-4 excels in both harmonic and intermodulation distortion control. This exciter is the perfect choice for those seeking premium sound quality and reliability in audio design projects.
Curious about how to create invisible sound with exciters? In this blog, Ben Zenker, an expert with more than 15 years of experience and 10 internationally reviewed publications, shares his in-depth knowledge on material selection, installation and optimising sound quality. An indispensable resource for the passionate DIY audio enthusiast.
Xcite offers both 4Ohm and 8Ohm exciters to suit various project needs. The choice depends on your setup. Usually, 4Ohm is preferred for the final configuration, such as using 1x 4Ohm, 2x 8Ohm in parallel, or 4x 4Ohm in a serial-parallel combination. If you need guidance, how to wire several exciters, check out the blog.
Looking in detail, 8Ohm exciters have a lighter voice coil due to a smaller winding diameter, which slightly enhances high frequencies although the inductivity is higher.
At higher volumes, all loudspeakers naturally produce distortion due to non-linearities in their voice coil, magnet, and stiffness design. The exciter design plays a crucial role in determining the level of distortion—a well-designed exciter minimizes it. For panel speakers, distortion is more complex than in traditional speakers, as the exciter is the primary source of distortion, while the panel and construction amplify it. Xcite units are engineered to produce low distortion, ensuring minimal distortion in the source of the final assembly.
Distortions in panel speakers arise from three sources: the exciter, the panel and assembly, with the exciter being the primary contributor. These distortions primarily include harmonic and intermodulation distortions caused by non-linearities in Bl(x) and Kms(x) of the exciter. By filtering the sound pressure using the inverse fundamental frequency response, the influence of the panel’s radiation can be removed, isolating all distortion at the system's input - the exciter. This technique, known as Equivalent Input Harmonic Distortion (EIHD), enables precise analysis of distortions at the exciter level. Xcite uses advanced simulations to identify and optimize the root causes of Bl(x) and Kms(x) non-linearities, minimizing distortion and delivering high-performance results. For detailed measurements, refer to our datasheets.
Motor efficiency factor β measures how efficiently the exciter converts electrical power into mechanical force. A higher value directly translates to greater sensitivity per Watt. Xcite represents this factor on a logarithmic scale to compare the performance of various products, including 4Ohm and 8Ohm exciters. Simply put, a 1dB higher motor efficiency factor means 1dB more in the passband.
Motor efficiency factor is determined by the motor design and influenced by factors such as coil winding layout, material resistivity, and magnetic field strength. Notably, it remains independent of the wire length and cross-sectional area of the wire, allowing for direct comparisons between 4Ohm and 8Ohm exciters. In our datasheets, we express the motor efficiency factor β logarithmically, highlighting differences in passband efficiency per Watt across exciters. This enables a clear evaluation of exciter performance in various configurations. For detailed insights, consult our measurement graphs with the corresponding motor efficiency factor for each product.
