ESB car audio 3.28 Tweeter Pair 1.1"/28 mm Series 3000

The tweeter uses a Torcon® diaphragm for homogeneous sound, with an external suspension covered by a high-loss damping material to eliminate edge vibrations and resonance. The dome has extremely reduced mass and is much less subject to mechanical deformations compared to other tweeters, while guaranteeing a homogeneous, linear and very extended response.

The 28 mm voice coil has an aluminum support and a very light copper-coated aluminum wire. The voice coil is vented and damped with fluid iron oil. The special SVS ventilation design offers two advantages: optimal voice coil cooling and the ability to avoid air compression on the back of the dome.

The N42 neodymium magnet, a type of magnet with significantly higher performance than "standard" magnets, is optimized with computer simulations to achieve better efficiency and improve linearity.
