The 2000 Series include advanced technologies for car audio speaker to serve the music in car. All the knowledge and experience of ESB R&D has been transferred to those special components, to obtain maximum audio performance as bandwidth, dynamic in music response and more ﬁdelity reproduction of sound details.

The new 2000 series arises from the experience gained with the 3000 series, with which it shares many constructive and technological choices. Same basket and same cone for the woofer, our special UMA mid-high unit and the silk dome tweeter available in two different sizes. Choose your 2 or 3-way kit, you will have the high technology of the most advanced series at an even lower price.
The ABS basket, reinforced with fiberglass, have been engineered in order to obtain the maximum in terms of torsional rigidity (bending), but at the same time offer the minimum resistance to the passage of air displaced by the cone from the rear face. The basket plays a fundamental role in aligning the coil in the magnetic circuit, its rigidity is crucial. A factor of no secondary importance is the damping of this component, often metal baskets tend to resonate, and this significantly alters the final sound result of the speaker. The ABS frame allows for a better clamping force torque than typical pressed steel frames and ensures that the voice coil remains well centered within the magnetic field.
The paper cone is the best marriage of lightness, stiffness and the ability of the cone to dampen any unwanted vibration (read: distortion).
The waterproof treatment does not change the appearance and parameters of the speaker like the shiny polymers that add an appreciable amount of mass to the cone itself and significantly modify the sonic result. The treatment protects the cone from water dripping (like inside a door panel), as well as accidental splashes on the front of the cone.
The voice coil of the woofers uses an aluminum support and a winding with a double layer technology of copper wire with an aluminum core. The long stroke design was chosen to improve sensitivity and efficiency while keeping distortion to a minimum. All these speakers are equipped with a motor with a grade Y-35 Ferrite magnet, a type of magnet with significantly higher performance than the classic "standard" ones. The metal parts of the engine use low carbon steel and have been designed to obtain the maximum magnetic saturation, this guarantees the best electroacoustic parameters.
The 2000 series tweeters use a silk-impregnated thin fabric dome diaphragm for a smooth, smooth sound, with an outer suspension of the same material but covered with a high-loss damping material to eliminate edge vibration and resonance. The dome is of extremely low mass and is much less susceptible to mechanical deformation than other models, yet it provides a smooth, linear and very extended response.
The 28 mm voice coil has an aluminum support and very light copper-coated aluminum wire, ventilated and damped with iron-fluid oil and with anti-resonance chambers. The special ventilation design, SVS (Surround Vented System) provides optimal cooling to be able to handle high power and avoiding compressing the air at the back of the dome, with a great reduction in distortion.
High-grade neodymium magnets such as N-42, is optimized with computer simulations to get better efficiency and improve linearity, to ensure greater and better power management and increase the bandwidth and efficiency.
