The ESB Tremila Series 3.25 is a high-quality 1-inch dome tweeter built for smooth, detailed sound. Sold as a pair.
3.25
1"/25 mm Dome Tweeter
The tweeter uses a silk-impregnated thin fabric dome diaphragm for a smooth, natural sound. The outer suspension is covered with a high-loss damping material to eliminate edge vibration and resonance. The dome is extremely low mass, making it less susceptible to mechanical deformation than most tweeters. This delivers a smooth, linear and extended frequency response.
The 25 mm voice coil uses an aluminium support with lightweight copper-coated aluminium wire. It is ventilated and damped with iron-fluid oil for controlled, accurate performance.
ESB's SVS ventilation design serves two purposes: it keeps the voice coil cool and prevents air compression behind the dome. The neodymium N42 magnet is computer-optimised for improved efficiency and better linearity — a significant step up from standard magnet designs.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
