Arcosia 7-208 by ETON
The ETON Arcosia 7-208 is a 6.5-inch (16.5 cm) mid-bass driver. The dynamic diaphragm geometry made from magnesium composite materials and an anodized, perforated magnesium diaphragm with olefin film characterize its construction. The perforations create bubble-shaped bulges that act as partial vibration absorbers. A two-component diaphragm technology, a hand-coated dust cap, and an optimized motor design are integrated. The ferrite magnet system utilizes a symmetrical magnetic field geometry as well as effective ventilation with optimal air circulation and heat dissipation. The frequency range is 50–3000 Hz, the nominal impedance is 8 Ω, and the power handling is 100 watts RMS. Specified parameters include 89 dB (1 W/1 m), a resonance frequency of 31 Hz, Xmax electrically ±5.5 mm and mechanically ±9.5 mm. Other parameters: Qts 0.32, Qms 5.88, Qes 0.34, Le 0.87 mH, BL 8.0 Tm, Sd 137 cm², Mmd 16.3 g, CMS 1.25 mm/N, RMS 0.67 kg/s, and VAS 32.9 liters.
