ESB 8.028 8000 Series 1.1" Dome Tweeters 110w RMS Pair

ESB 8.028 1.1"/28 mm Dome Tweeter

The 8000 Series can be considered the direct heir to the 7000 Series. The goal was to renew a variety of speakers in itself exceptional, with the help of the latest technologies and the use of the best materials available today, always with installation versatility in mind. Key to the development of this type of car speaker system was to build on their exceptional musicality. In the 8000 Series, every detail was treated with the utmost care, from the choice of materials, the forms, construction and finishing of the baskets, to the ventilation systems of the magnets and  voice coils. We have improved what was thought to be difficult to improve and we strongly believe we have laid the foundation for a new series of exceptional car speakers.

All the parts that make up this tweeter have been made with the CNC process. This is a very expensive and time consuming manufacturing process, but ensures perfect geometry and impeccable aesthetics. A mix of precious materials such as brass, stainless steel and Avional aluminum are used together for a unique product.

The tweeter uses a very large vented neodymium motor magnet optimized with computer simulations (FEA) to obtain great efficiency and improved linearity all along the voice coil’s excursion. The neodymium magnet is of a high-grade to neutralize magnetic loss at elevated temperatures and concentrate more force in less volume.

The Torcon® soft dome, an exclusive Polyphenylene Sulfide (PPS) with a high-performance fiber, offers superb heat resistance, low weight, excellent self-damping, to obtain a free resonance frequency response above the audible range. The semi-catenary profile on our diaphragm provides maximum stiffness at the tip of the dome. The result is clean, smooth and transparent sound reproduction with high efficiency from 940Hz to 25KHz with high power handling capacity.

The center ventilation hole provides an optimal cooling of the moving coil to handle high power without dynamic compression, while at the same time, reducing the compression of the air at the back of the dome with a great reduction of distortion and extended response to lower frequencies. A special acoustic resistance helps control the tweeter Qts. Residual resonance is neutralized by the dB Cloth® under-dome damping material which extends the frequency response to the lower limits and reduces harmonic distortion.

To mount the tweeter, the installer can use the classic solution that ESB has recommended for decades: an aluminum threaded ring.
