The first in our Special Car Speaker Series, a new project, were designed for Audi vehicles… the Audi A4, Audi A6 and Audi Q5. The ESB team’s challenge was match Audi’s unique speaker housings and original amplifier power (which was too low to properly drive high-quality speakers). It was not possible to replace the amplifier integrated in Audi’s entertainment system with our own. Our challenge was to develop new, higher quality speakers with equal or better efficiency than the originals. The depth of the speaker housings was also very limited (only a few centimeters). It was impossible to adapt cone speakers to traditional voice coils and magnets. So, we developed all new speakers (in the 8" and 6.5" sizes) with neodymium magnets and special voice coil. The model numbers of these new speakers are ESB CS-W81 and ESB CS-W61 (they can also be used in other cars). These speakers have a shallow depth and can be used with special adapters (in an elegant aluminum Ferrari red color) to match car spaces exactly. Also, the connectors match the car’s original wire connectors for ultimate plug and play convenience. For the 8" and 6.5" Audi speakers, we developed two new tweeters,… the 1.2" ESB CS-T31 and the 1" ESB CS-T21. These tweeters can also be used in other cars. The speakers included in our Car Kits have different model numbers because they include the adapters. Thus, the ESB CS-W81 becomes the ESB A6-F81 for the front of the Audi A6, and ESB A4-F81 for the front of the Audi A4 and Audi Q5. The same applies to our other Audi speakers.
