ESB Audio - 9000 Series - 9.1T-25 1"/25 mm High-End Dome Tweeter
 
Main Features
- Silk dome impregnated with resin with integrated suspension. This dome is made in a single piece that also includes the suspension. This greatly reduces weight allowing the tweeter to reproduce very high frequencies. The absence of joints prevents break-up and/or vibration phenomena.
- Magnet made from N52H neodymium, best both for the magnetic force in relation to the mass, and for high temperature support (120° F vs. 80° F of a standard neodymium magnet).
- The pole cup has twelve axial holes in the bottom to eliminate the air back pressure caused by the movement of the dome. This solution helps to reduce the distortion that would inevitably be generated due to the deformation of the delicate silk dome, and also helps to reduce the tweeter frequency resonance.
- The back of the tweeter includes a threaded hole that greatly increases the installation possibilities in unconventional locations inside cars.
- Wide 25 mm lightweight aluminum voice coil with aluminum copper clad winding contributes significantly to the large bandwidth extension of this tweeter.
- Magnet plate made of ultra-low-carbon steel.
- Main body made in ABS.
- The connecting cables are super flexible with high silver content to reduce electrical connection losses.
- Gold-plated copper terminals.
- Felt damper for controlling and reducing dome resonance.
- Light stainless steel grill for dome protection.
- 8 installation accessories for different car models (included).
