This precision driver reproduces deep, authoritative lows and sparkling, extended highs with remarkable clarity, capturing both the subtlest musical details and broad emotional expression.\n\n\n7Hz–45kHz Ultra-Wide Frequency Response\nWith a frequency response spanning approximately 7Hz–45kHz, EDZ achieves high sensitivity and excellent transient performance. Every nuance—from delicate harmonic overtones to visceral low-end impact—is rendered with impressive resolution, creating an immersive and highly detailed listening experience.\n\n\nDual Damping System for Pure, Natural Sound\nEDZ incorporates a refined dual damping system that effectively controls unwanted peaks and resonances.
