ETON Graphite 80

The Graphit 80 from ETON is a 3" (8cm) midrange driver equipped with a carbon fleece sandwich membrane and an anodized aluminum dust cap, which enables optimized heat dissipation. A powerful neodymium magnet and a stiffened, ventilated die-cast aluminum basket characterize this high-quality midrange driver. With a nominal power of 25 W RMS and a music power handling of 40 W at an impedance of 4 ohms, the Graphit 80 offers a characteristic sound pressure of 86 dB. Manufactured and developed in Germany, this midrange driver offers impressive sound quality and reliability.

High-end 80 mm (3 inch) midrange driver with carbon fleece sandwich membrane, anodized aluminum dust cap for optimized heat dissipation. The powerful neodymium magnet in combination with the stiffened and optimally ventilated die-cast aluminum basket results in an Ektra-class midrange driver. Symmetrical wire, 25 W RMS, 40 W music power handling, 4 ohm impedance and a characteristic sound pressure of 86 dB. Manufactured and developed in Germany.
