ESB Audio - 9000 Series - 6.5" 3 way speaker system

ESB Audio 9000 Series - 3 Way Speaker System 
 
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.
- The cone is made of high modulus carbon molded under vacuum and autoclave, a technology rarely used in speakers because of its cost, but brings enormous benefits in terms of naturalness of reproduction and high transient dynamics.
- The NBL rubber surround has a shape designed to ensure very smooth movement at very low excursion, becoming increasingly controlled as the excursion increases and approaches the limit. This, too, helps to make this speaker extremely dynamic and capable of handling high powers.
- The CNC-machined aluminum ring secures the rubber suspension on the edge, ensuring perfect fastening and centering.
- CNC-machined aluminum grille (optional).

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.
- The NBL rubber surround has a shape designed to ensure very smooth movement at very low excursion, becoming increasingly controlled as the excursion increases and approaches the limit. This, too, helps to make this speaker extremely dynamic and capable of handling high powers.
- CNC-machined aluminum grille (optional).

9.1T-25
1"/25 mm High-End Dome Tweeter
 
- Silk dome impregnated with resin with integrated suspension. This dome is made in a single piece that also includes the suspension. This greatly reduces weight allowing the tweeter to reproduce very high frequencies. The absence of joints prevents break-up and/or vibration phenomena.
- Magnet made from N52H neodymium, best both for the magnetic force in relation to the mass, and for high temperature support (120° F vs. 80° F of a standard neodymium magnet).
- The pole cup has twelve axial holes in the bottom to eliminate the air back pressure caused by the movement of the dome. This solution helps to reduce the distortion that would inevitably be generated due to the deformation of the delicate silk dome, and also helps to reduce the tweeter frequency resonance.
- The back of the tweeter includes a threaded hole that greatly increases the installation possibilities in unconventional locations inside cars.
- Wide 25 mm lightweight aluminum voice coil with aluminum copper clad winding contributes significantly to the large bandwidth extension of this tweeter.
- Magnet plate made of ultra-low-carbon steel.
- Main body made in ABS.
- The connecting cables are super flexible with high silver content to reduce electrical connection losses.
- Gold-plated copper terminals.
- Felt damper for controlling and reducing dome resonance.
- Light stainless steel grill for dome protection.
- 8 installation accessories for different car models (included).
