ESB Audio 8.003UMA Ottomila 75mm Midrange-28mm Tweeter (pair)

ESB Audio 8.003UMA Midrange-Tweeter Combo, 3"/75 mm Midrange + 1.1"/28 mm Tweeter (pair)

Key Features

• This special and exclusive component speaker is a concept designed back in the 1970s. Its goal is to concentrate the midrange and tweeter emissions into a virtual single point. This minimizes phase shifts and irregularities at the crossover.
• All parts of this component are manufactured using a CNC process. This is a very expensive and time-consuming manufacturing process, but it ensures perfect geometry and impeccable aesthetics. A blend of precious materials such as brass, stainless steel, and Avional aluminum is used to create a unique product.
• Each component uses a very large, ventilated neodymium motor magnet, optimized with computer simulations (FEA) for greater efficiency and improved linearity throughout the voice coil's excursion. The neodymium magnet is of high quality to eliminate magnetic losses at high temperatures and concentrate more power in a smaller space.
• The tweeter uses a Torcon® soft dome, an exclusive Polyphenylene Sulfide (PPS) with high-performance fiber, which offers excellent thermal resistance, low weight, and excellent self-damping to achieve a free resonance frequency response beyond the audible range.
• The midrange's unpressed cellulose pulp cone with an exponential shape and vinyl ester resin coating ensures a perfect balance between rigidity, weight, and self-damping. The cellulose pulp guarantees a very natural and linear reproduction with excellent extension at high frequencies.
• Great attention was paid to the ventilation of the two components, with single axial ventilation in the tweeter and multiple vents in the midrange. To improve control and damping, acoustic resistance was introduced in both components.
• Together, these two components are able to reproduce with perfect linearity the entire frequency spectrum from 95 Hz to 25 kHz.
