ESB Audio 3.69 6x9"/150x230 mm Woofer (pair)
Main features
- ABS body reinforced with fiberglass. The body is designed to achieve maximum torsional rigidity (bending resistance), while at the same time offering minimal resistance to air flow.
- Pressed on a paper cone with a water-based treatment. It is widely recognized that cones made from paper are the ideal combination of lightness, stiffness, and the cones' ability to reduce unwanted vibrations (read: distortion).
- With high damping single-wave rubber edge spring. The Perbunan® rubber edge is much more stable to temperature changes than regular rubber.
- The 25mm voice coil uses an aluminum support and double-layer winding technology with copper wire with an aluminum core.
- High-quality ferrite magnet, a type of magnet that has significantly higher performance than "regular" magnets.
