ESB Audio 9.1T-28 Novemila 28mm Silk Dome Tweeter (pair)

ESB Audio 1.1"/28 mm Silk Dome Tweeter with CNC Mounting (Pair)

Key Features

• TCA system for airflow control, reducing turbulence, noise, and managing diaphragm damping.
• Pole piece CNC machined from a single piece of ultra-low carbon steel.
• Main magnet made of N52H neodymium, the best both for magnetic force relative to mass and for high-temperature resistance (120°F vs. 80°F for standard neodymium magnets).
• Magnetic plate made of ultra-low carbon steel.
• Secondary or upper magnet used to stabilize and regularize the magnetic flux, and to concentrate it only in front of the voice coil, thus increasing efficiency, controllable power, reducing distortion, and expanding the bandwidth.
• A pure copper ring helps reduce the voice coil inductance so that it provides minimal resistance during high-frequency reproduction. This means better high-frequency response, allowing the speaker to reproduce high-frequency sounds more accurately. Reduced inductance improves the handling of rapid transitions in audio signals. This enhances the speaker's ability to reproduce transient sound pulses more accurately.
• FCA system: special structure for controlling the airflow moved by the diaphragm. This creates a periodic damping resistance, determining that the release of the energy accumulated in the diaphragm's movement occurs in a controlled and rapid manner, without persistent oscillations. This contributes to a more accurate and faithful response to the sound source, as well as precision and overall quality of the listening experience.
• The very light aluminum voice coil uses a high-strength aluminum alloy to reduce its thickness and weight. The winding is also aluminum with a pure copper "sheath." This results in the perfect combination of wire strength and weight.
• Pure Japanese silk dome impregnated with resin with integrated suspension. This chain-profile dome is made in a single piece that also incorporates the suspension. This significantly reduces weight, allowing the tweeter to reproduce very high frequencies. The absence of joints prevents disintegration and/or vibrations.
• Felt ring to eliminate any harmful vibrations.
• Light stainless steel protective mesh to protect the dome.
• The faceplate is not merely cosmetic but acts as an acoustic lens. Its shape dramatically reduces side diffractions – an unwanted phenomenon in car installations where windows create detrimental diffractions.
• Very flexible cables with a high silver content to reduce electrical connection losses.
• Aluminum threaded mounting ring.
• Finished stainless steel ring included.
