ESB Audio 9000 Series - 3 Way Speaker System with the 9.1T-28 tweeter
9.6W
6.5"/165 mm High-End Mid-Woofer
- The pole cup, designed with magnetic flux analysis software, helps to achieve perfect and homogeneous saturation of the magnetic gap for the benefit of the voice coil stroke. Always immersed in constant magnetic flux, this reduces distortion and increases dynamics.
- Generously sized neodymium magnet: This very powerful magnet is made from a high-temperature resistant neodymium and allows the size and bulk of the magnetic motor to be greatly reduced. The equivalent magnetic force from a standard ferrite magnet would require larger dimensions of the speaker itself.
- Pole yoke with special internal ventilation, ensures a long life of the voice coil.
- The terminals accept large gauge cables and are gold-plated to prevent any loss of power generated by the amp.
- The cast-aluminum and powder-coated basket offers very low resistance to the passage of air, and its shape (verified by FEM analysis) reduces vibration and resonance.
- A special spider device, screwed to the central pole, ensures the spider damper clamping.
- Conex™ spider damper is inside the voice coil with balanced and progressive stiffness for a perfect controlled ride
- An enormous voice coil ensures highest-in-class power handling and guarantees unequaled speaker dynamics. The design of this voice coil ensures that it remains fully immersed in the magnetic field for much of its excursion, minimizing distortion. The voice coil former is made of aluminum with ventilation holes and black anodization in order to better dissipate heat. Underhung voice coil: the length of the voice coil winding is shorter than the height of the magnetic gap. This design allows lower distortion at lower excursions and more precise control over the movement of the voice coil.

9.3M
3"/75 mm High-End Cone Midrange
- The magnet pole yoke, designed with magnetic flux analysis software, helps to achieve perfect and homogeneous saturation of the magnetic gap for the benefit of a coil stroke and reduction of distortion and increased dynamics.
- Large neodymium magnet. This neodymium high-temperature resistant magnet is one of the most powerful motor magnet structures for this size car audio midrange driver. It is made from a high-grade neodymium and allows the size and bulk of the magnetic motor to be greatly reduced.
- TCA to control the flow of air moved by the cone creates aperiodic damping resistance and dictates that the release of energy accumulated in the movement of the speaker 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 to the accuracy and overall sound quality.
- Pole plate CNC machined from a solid piece of ultra-low-carbon steel.
- Gold-plated soldering terminal helps to save space and prevent any loss of power generated by the amplifier.
- Die cast-aluminum and powder-coated basket offers very low resistance to the passage of air, and its shape (verified by FEM analysis) reduces vibration and resonance.
- Wide, lightweight Nomex voice coil with aluminum winding contributes significantly to the wide bandwidth extension.
- Large balanced Conex™ spider damper device ensures linear excursion in both directions thereby reducing distortion.
- Collar for joint voice coil and cone. This distributes the pressure on the cone over a large area for reduced deformation and distortion.
- Cone is made with vacuum and autoclave molded high-modulus carbon, a technology rarely used in loudspeakers because of its cost, but it brings enormous benefits in terms of naturalness of reproduction and high dynamics at transients. This is made in a single piece by eliminating the dust cap. On a component of this small size, this solution offers incredible advantages in homogeneity of dispersion and regularity of frequency response at the high end.
- CNC-machined aluminum grille (optional).

9.1T-28
1.1"/28 mm High-End Dome Tweeter
- 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.
