Installed at Mediocre Customs, Cary IL. We fit them at our Cary shop with the right adapters or custom pods, then wire and tune them so the front stage sounds right from the driver's seat.
The ESB 9.1T-25 is the 1-inch tweeter from ESB's 9000 (Novemila) series, winner of the EISA In-Car High-End Component award for 2024–2025. A pure silk dome with integrated suspension and an N52H neodymium motor deliver smooth, detailed highs, and it ships with eight car-specific mounting flanges so it drops into factory tweeter locations in many vehicles.

- Super-light aluminum voice coil
- 100 W nominal / 200 W transient
- 1.6 kHz – 25 kHz, 91.5 dB sensitivity
