ESB Audio 5.UMA Mid-High Unit, 2"/50 mm Mid. + 1.1"/28 mm Tw. (pair)
Main Features
- This special and exclusive component driver is a concept conceived way back in 1970’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.
- All the parts that make up this component were made with the CNC process. This is very expensive and requires a lengthy manufacturing process, but ensures perfect geometry and impeccable aesthetics. Moreover, the parts are made with Avional aluminum with deep oxidization.
- Both components use a very large neodymium motor magnet optimized with computer simulations (FEA) to obtain a great efficiency and improved linearity all along the voice coil’s excursion. The neodymium magnet is of a high grade to eliminate magnetic losses at elevated temperatures and to concentrate more force in less space.
- The tweeter dome, made of high module carbon fiber with integrated soft cloth suspension, offers superb heat resistance, low weight and excellent self-damping, with a natural and linear response and a very low frequency extension.
- The midrange, also manufactured in carbon fiber, integrates a suspension in synthetic foam, ensuring a perfect balance between rigidity weight and self-damping. The carbon fiber guarantees an extremely natural and linear reproduction with an excellent extension at the ends of the band.
- Great attention was given to the ventilation of the two components, through multiple axial holes. Residual resonances are neutralized by the under dome dB Cloth® damping material. This extends the frequency response to the lower limits and reduces harmonic distortion. To improve control and damping an acoustic resistance was adopted on both components.
- Combined together, the two components are able to reproduce with perfect linearity the entire spectrum from 500Hz to 25KHz.
- Small permanent magnets fix the tweeter and midrange grill in the correct position and these are easy to remove for customization.
