Technology meets performance — pushing the limits of cost versus capability.
ESB's goal for its 4000 Series was to push the limits of cost vs. performance. The expensive design of the 3"/75 mm midrange driver and its high-grade neodymium magnet guarantees a level of efficiency that supports high sound pressure even when paired with low-power factory amplifiers.
Even the 4000 Series' premium matt-black steel grilles lend a refined aesthetic on par with more expensive systems. With ESB's 4000 Series, never has such quality, clarity, and accuracy been more affordable.
