S2-T25 by AI-Sonic
The S2-T25 from AI-Sonic is a dome Tweeter that impresses with its 25 mm silk dome, offering soft and audiophile sound colors. It is ideal for car Hi-Fi applications and demanding sound solutions. Thanks to its strong neodymium magnet, it delivers excellent impulse fidelity and control. With an efficiency of 93 dB SPL, it can be easily operated with moderate amplifier power. The S2-T25 has a wide frequency range of 3,800 to 25,000 Hz and a compact design that allows for flexible installation. These features make it particularly recommended for SQ systems and OEM upgrades.
AI-Sonic S2-T25 – 25 mm Silk Dome Tweeter for Demanding Sound Solutions
The AI-Sonic S2-T25 Tweeter is aimed at those who value fine highs, precise spatiality, and easy integration in the car Hi-Fi sector. Especially in SQ-oriented setups or as an upgrade for factory systems, this 25 mm silk dome Tweeter makes perfect sense. I recommend the S2-T25 whenever a smooth, distortion-free high-frequency reproduction is required – for example, in high-quality front systems or active 3-way installations, where the Tweeter should not be overly pronounced.
Technical Highlights of the AI-Sonic S2-T25
- 25 mm silk dome – provides soft, audiophile sound colors and prevents the typical "sibilance" of many metal domes. This is a real advantage for long, relaxed listening, especially in high-dynamic music.
- Strong neodymium magnet – compact and lightweight, yet with high field strength for excellent impulse fidelity and control, even with fast transients.
- High efficiency (93 dB SPL) – can be easily operated with moderate amplifier power, making it suitable for factory wiring or DSP setups with smaller amplifiers.
- Wide transmission range of 3,800 to 25,000 Hz – covers the entire fine detail range and provides airy, open sound stages.
- Compact design: With only 15 mm installation depth and 49 mm mounting diameter, the S2-T25 fits into many original mirror triangles, A-pillars, or door boards.

Application Area & Compatibility
The S2-T25 is suitable for all common car Hi-Fi and SQ systems, whether as a replacement for factory tweeters, in an active front system, or as an upgrade to existing AI-Sonic components. It is particularly recommended in combination with the AI-Sonic S2-W6 and S2-C6.2 midwoofers or as a matching tweeter for high-quality 2- and 3-way concepts. Those who value precise soundstage and clean voice reproduction will find this Tweeter a great choice.
What to Consider When Installing
- The low installation depth allows for flexible mounting – ideal for mirror triangles, A-pillars, or flat door boards. However, check beforehand if there is enough space for the connection cables.
- The S2-T25 should be mounted at ear level and slightly angled if possible, to achieve maximum spatiality and detail.
- With 4 Ohm impedance, pay attention to the appropriate crossover design – especially if you are upgrading an existing system or using a DSP.
- In active setups, do not set the high-pass filter below 3,500 Hz to protect the tweeter from overload.
Conclusion: AI-Sonic S2-T25 Tweeter – Silk Dome for Fine Highs
If you value detailed, non-annoying highs and an easy installation, the AI-Sonic S2-T25 offers a practical tweeter for SQ and everyday projects. Especially for OEM upgrades and compact door concepts, the S2-T25 is my first choice.
