ESB car audio 3.69C 2-way convertible coaxial speaker system 6x9" Woofer + 1" Tw + Crossover

Basket in ABS reinforced with fiberglass. The basket was designed to achieve the maximum in terms of torsional rigidity (bending resistance), but at the same time offers minimal resistance to air passage. Paper cone (woofer) with waterproof treatment. It is widely recognized that paper cones represent the ideal combination between lightness, rigidity and the cone's ability to dampen any unwanted vibration (read: distortion). Single-wave rubber surround with high damping.

The surround is much more stable to temperature variations compared to standard rubber. The 25 mm voice coil uses an aluminum support with double-layer winding technology of copper wires with an aluminum core. The tweeter has a thin fabric dome diaphragm impregnated with silk for homogeneous sound, with an external suspension covered by high-loss damping material to eliminate edge vibrations and resonance.

The dome has extremely reduced mass and is much less subject to mechanical deformations compared to other tweeters, while guaranteeing homogeneous, linear and very extended response. High quality ferrite magnet (woofer) and N42 neodymium magnet (tweeter) with performance significantly superior to "standard" magnets.
