TWEETER 1.1”/28 MM SILK DOME

Main featurs include TCA System for back air flow control which reduces turbulence, noise, and controls the damping of the dome. Pole cup CNC machined from a solid piece of ultra-low-carbon steel. Main magnet made from N52H neodymium, best both for the magnetic force in relation to the mass, and for high temperatures support (120° F vs. 80° F of a standard neodymium magnet). Magnet plate made of ultra-low-carbon steel. Secondary or superior magnet used to stabilize and regulate the magnetic flux and concentrate it only in front of the voice coil, increasing efficiency, manageable power, distortion and bandwidth. Pure copper ring helps reduce the inductance of the voice coil so that it offers minimal resistance during high frequency reproduction. This means better high-frequency response, enabling the speaker to reproduce high-frequency sounds more accurately. Reduced inductance contributes to better handling of rapid transitions of audio signals. This improves the speaker's ability to more accurately reproduce transient sound pulses. FCA System: a special structure to control the flow of air moved by the dome. This creates a periodic damping resistance and dictates that the release of the energy accumulated in the movement of the dome occurs in a controlled and fast manner, without creating persistent oscillations. This contributes to a more precise and faithful response to the audio source and accuracy, and the overall quality of the audio experience. Super light aluminum voice coil uses a high-strength aluminum alloy to reduce its thickness and its weight. The winding is also aluminum with a pure copper “skin”. This results in a perfect combination of resistance and weight of the wire. Pure Japanese silk dome resin impregnated with integrated suspension. This catenary profile dome is made in a single piece that also includes the suspension. This greatly reduces the weight, allowing the tweeter to reproduce very high frequencies. The absence of joints prevents break-up and/or vibrations. Felt ring to eliminate any deleterious vibration. Light stainless steel grill for dome protection. The faceplate isn’t just cosmetic, but acts as an acoustic lens. Its shape dramatically reduces side refractions unwanted occurrence in a car installations where windows create harmful refractions. Super flexible cables with high silver content to reduce electrical connection losses. Aluminum threaded fixing ring. Finishing stainless steel ring (optional). Technical Specifications nominal Impedance: 4 Ohm; Nominal Power Handling: 110 Watt; Transient Power: 220 Watt; Frequency Response: 1.4 KHz ~ 25 KHz; Sensitivity: 94.5 dB 2.83v/1m.
