The ESB 3.65 is a wide-range speaker from the 3000 series, designed to bring natural midrange clarity to your car audio setup. It is versatile enough to function within a 3-way system alongside a woofer and tweeter or to act as a tweeter replacement in a 2-way configuration. This component handles 60 W RMS and can reach a peak of 120 W, delivering a frequency response from 130 Hz up to 22 kHz with a sensitivity of 86 dB. Its construction focuses on stability and precision, featuring a pressed paper cone with waterproof treatment that balances lightness and stiffness to dampen unwanted vibrations. A single wave Perbunan® rubber surround ensures the speaker remains stable across varying temperatures, while the ABS basket reinforced with fiberglass provides high torsional rigidity without obstructing airflow. Inside, a 20 mm voice coil with an aluminum support and double-layer copper-aluminum winding is driven by a powerful N42 neodymium magnet. To further refine the sound, the speaker includes a CNC aluminum center plug that helps linearize and extend high frequencies. These technical choices minimize distortion through optimized motor and suspension behavior, making it an ideal choice for listeners who want an accurate and detailed audio reproduction in their vehicle.
