Technology meets Performance
ESB’s goal for its new 4000 Series was to push the limits of cost vs. performance. We know of no other car speakers currently on the market at these price points that make use of the same advanced materials or surpasses their remarkable performance. The particularly expensive design of the 3”/75 mm midrange driver and its high-grade, high-energy neodymium magnet guarantees a level of efficiency that supports high sound pressure levels even when paired with low-power factory amplifiers. Even the 4000 Series’ premium matt black steel grilles lend them a more refined aesthetic on par with more expensive speaker systems. They make a bold statement, yet blend harmoniously with just about any car interior. With ESB’s new 4000 Series, never has such quality, clarity, and accuracy been more affordable.
