ESB 2.6K2 Duemila 2-Way High Preformance Speaker System 6.5" 28mm Tweeter

Woofer: Cones made of paper are the best marriage of lightness, stiffness and the ability of the cone to dampen any unwanted vibration. The Perbunan rubber ensures a dual function of high damping and great transversal stability, this means that the cone is “forced” only to the vertical movement, eliminating the transversal movements that could cause contact with the coil and the magnet. The 25 mm voice coil of the woofer uses an aluminum support and a winding with a double layer technology of copper wire with an aluminum core. 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 material used, in addition to not being as sensitive to thermal changes, is also non-resonant. In addition, 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. All these speakers are equipped with a motor with a grade Y-35 Ferrite magnet, with significantly higher performance than the classic “standard” ferrite magnets, this ensures greater ease of management of the power applied to the speaker and a its superior efficiency. 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 as the eddy currents that are generated by the movement of the cone are largely canceled. Tweeter: 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. 2.028 – 1.1″/28 mm Dome Tweeter 28 mm voice coil Neodymium magnet Torcon® soft dome Under-dome dB Cloth® damping material Ferrofluid cooling and damping Nominal Impedance: 4 Ohm Nominal Power Handling: 90 Watt Transient Power: 180 Watt Freq.
