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.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUltra-low carbon alloy steel pole piece CNC-machined using magnet analysis software (FEM), cold forged in one-piece creates a perfect geometry. This produces an extra magnet force concentration just in front of the voice coil, focusing the magnetic force where needed.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHigh-grade neodymium magnet. Not all magnets of equal size are equal in strength. This high grade (N-52), high-energy magnet provides a high resistance to demagnetization and is over 25% stronger for the same mass than more common lower grade (N-48) magnets.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDie cast aluminum alloy basket frame. This design structure offers great rigidity and minimal resistance to airflow movement without altering sound quality. The casting of this aluminum basket follows strict procedures that ensure compliance with regulatory specifications and help maintain consistent casting quality.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCNC-machined ultra-low carbon alloy steel pole plate. This type of manufacturing process ensures perfect flatness so it sits perfectly flush over the magnet without reducing any crucial magnetic flux.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe large aluminum copper-clad vented voice coil can handle very high power while reproducing music with extreme realism and high dynamics.
