DAYTON AUDIO EC30-4 Speaker Driver Tweeter

The Dayton Audio Epique EC30-4 is a 30mm ceramic dome tweeter designed for high-frequency reproduction with extension up to 40kHz. It operates at an impedance of 4Ω and reaches a sensitivity of 92dB, with a power handling of 80W RMS, relying on an aluminum dome reinforced with a ceramic coating to maintain controlled vibration and limit deformation at high frequencies.

Intended for hi-fi systems and monitors, it combines an optimized rear chamber and internal damping materials allowing parasitic resonances to be reduced, resulting in clearer detail reproduction. The magnetic circuit integrates a copper cap and a Kapton voice coil former, acting on signal stability and reducing electrical variations, while the treated fabric surround contributes to maintaining consistent behavior over time. The assembly is based on a 3.6mm aluminum front plate with a honeycomb protective grille, ensuring mechanical rigidity while protecting the dome without blocking sound dispersion.
