25 mm voice coil for the tweeter 20 mm voice coil for the midrange N42 Neodymium magnet High temperature aluminum/copper vc Axial forced coil ventilation Silk dome tweeter Fiber reinforced paper cone midrange Fatigue and tear poly cotton spider Computer designed ABS frame Motor metal parts CNC machined Super soft roll rubber suspension Fatigue resistant lead wire, balanced conn. This special and exclusive component driver is a concept born way back in 70’s, its aim is to concentrate medium and tweeter emissions in a single virtual point. This minimizes phase delays and irregularities at the crossover point. Neodymium magnet is an high grade type for eliminate magnetic losses at elevate temperature and concentrate more force in less space. The tweeter has a silk-impregnated thin fabric dome diaphragm for a smooth sound, with an outer suspension covered with a high-loss damping material to eliminate edge vibration and resonance. Pressed paper cone with waterproof treatment (midrange), for the best marriage of lightness, stiffness and the ability of the cone to dampen any unwanted vibration. The voice coil uses an aluminum support and a winding with a double layer technology of copper wire with an aluminum core. ABS basket reinforced with fiberglass. The baskest 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. - Pressed paper cone with waterproof treatment. It is widely recognized that cones made of paper are the best marriage of lightness, stiffness and the ability of the cone to dampen any unwanted vibration (read: distortion). - High damping single wave rubber surround. The Perbunan rubber edge is much more stable when the temperature changes than the classic rubber. - The 25 mm voice coil uses an aluminum support and a winding with a double layer technology of copper wire with an aluminum core. - High grade ferrite magnet, a type of magnet with significantly higher performance than the classic "standard" ones. FEA motor optimized 25 mm copper/aluminum voice coil High temperature aluminum former Large high grade ferrite magnet Axial forced coil ventilation Fiber reinforced paper cone Oversized single wave rubber suspension Poly cotton spider ABS basket with self damping system Balanced symmetrical construction Computer optimized design Fatigue resistant lead wire, bal. connect. 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.
