2000
Speaker Series
The 2000 Series include advanced technologies for car speaker to accurately reproduce music in the car. All the knowledge and experience of ESB’s R&D has been transferred to these special components to obtain maximum audio performance as it relates to bandwidth, dynamics in music response, higher fidelity, and more detailed sound. A reference product for your car audio category.
A Reference Product for Your Category
The new 2000 Series arose from the experience gained from the 3000 Series, with which it shares many constructive and technological advances… the same basket, woofer cone, our special UMA mid-high unit, and our silk dome tweeter available in two different sizes. Choose from our 2 or 3-way installation kit. You will get the best technology in the most advanced car speaker series at an even lower price.
2000 Series - Speaker Systems
Woofer
The basket, made from ABS and reinforced with fiberglass, has been engineered to obtain the maximum torsional rigidity (resistance to bending), but at the same time, offering 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. Equally important is the damping of this component. Often, metal baskets tend to resonate, and this significantly alters the speaker’s sound quality. The ABS frame also 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 ideal marriage between lightness, stiffness and the ability of the cone to dampen any unwanted vibration (read: distortion). The waterproof treatment does not negatively impact the appearance or performance of the speaker like the shiny polymers that add an appreciable amount of mass to the cone itself and significantly modify the sound quality. Our treatment protects the cone from dripping water (like inside a door panel), as well as accidental splashes on the front of the cone.
The woofer voice coils use 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 grade Y-35 ferrite magnet motor, a type of magnet with significantly higher performance than "standard" magnets. The metal parts of the motor use low carbon steel and have been designed to obtain the maximum magnetic saturation. This guarantees the best electroacoustic performance.
Tweeter
The 2000 Series tweeters use a silk-impregnated, thin fabric dome diaphragm for a smooth sound, with an outer suspension of the same material, but covered in 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 tweeters, yet 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, called SVS (Surround Vented System), provides optimal cooling to handle high power and avoid compressing the air at the back of the dome, resulting in significantly lower distortion.
High-grade, N-42 neodymium magnet, are optimized with computer simulations for better efficiency and improved linearity, ensuring better power management and increased bandwidth and efficiency.
