4.100 4"/100 mm Cone Midrange
The ESB 4000 Series was designed to maximise performance at an accessible price point. The N-52 neodymium magnet delivers high efficiency, supporting high sound pressure levels even with low-power factory amplifiers. The premium matt black steel grille gives a refined finish that suits most car interiors. If you need a larger driver, the 4000 Series is also available as the ESB 4.165 6.5 inch component mid woofer at 150w RMS.
Features
- Ultra-low carbon alloy steel pole piece CNC-machined using magnet analysis software (FEM) and cold-forged in one piece for perfect geometry. Concentrates magnetic force directly in front of the voice coil.
- High-grade N-52 neodymium magnet — over 25% stronger for the same mass than common N-48 magnets, with high resistance to demagnetisation.
- Die-cast aluminium alloy basket frame for high rigidity and minimal airflow resistance, manufactured to strict regulatory specifications for consistent quality.
- CNC-machined ultra-low carbon alloy steel pole plate ensures perfect flatness, sitting flush over the magnet without reducing magnetic flux.
- Large aluminium copper-clad vented voice coil handles high power with excellent heat dissipation and lightweight construction for high dynamic accuracy.
- Long-fibre unbleached pulp cone with special external treatment balancing lightness, rigidity, and internal damping.
- Soft nitrile rubber surround suspension — UV-resistant and unaffected by temperature changes — with a special edge design for free, consistent forward and backward movement.
- Deluxe protective stainless-steel grille included.
