ESB car audio 8.028S Pair of 1.1"/28 mm tweeters with square bracket

All the parts that make up this tweeter have been produced with the CNC process. It is a very expensive and time-consuming production process, but it guarantees perfect geometry and impeccable aesthetics. A mix of premium materials such as brass, stainless steel and Avional aluminum are used together to obtain a unique product. The tweeter uses a very large ventilated neodymium magnet, optimized with computer simulations (FEA) to achieve great efficiency and better linearity throughout the entire excursion of the voice coil. The neodymium magnet is of high quality to neutralize magnetic loss at high temperatures and concentrate more force in less volume.

The soft Torcon® dome, an exclusive polyphenylene sulfide (PPS) with high-performance fiber, offers superb heat resistance, reduced weight, excellent self-damping, to achieve a free resonance frequency response above the audible range. The catenary profile of our diaphragm ensures maximum rigidity on the tip of the dome. The result is clean, homogeneous and transparent sound reproduction, with high efficiency from 940Hz to 25KHz and high power handling capacity.

The central ventilation hole ensures optimal cooling of the voice coil to handle high power without dynamic compression and, at the same time, reduces air compression on the back of the dome with a great reduction in distortion and extended response to lower frequencies. A special acoustic resistance helps control the tweeter's Qts. The residual resonance is neutralized by the dB Cloth® damping material under the dome, 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.
