Epique High Resolution Ceramic Dome Tweeter 30mm 4 Ohm EC30-4The Dayton Audio Epique EC30-4 Ceramic Dome Tweeter sets a new benchmark for high-resolution audio performance. Built to last, it is designed with meticulous precision and crafted from premium materials to ensure both exceptional sound and long-term reliability. The EC30-4 combines substance with style, featuring a rugged 3.6mm aluminum faceplate and a honeycomb mesh protective grill that deliver durability without compromising elegance. Its advanced ceramic dome construction brings out the finest details in music reproduction, producing crystal-clear highs and unmatched transparency that remain consistent across listening environments.
Engineered for Transparency At the heart of its design is a 30mm aluminum dome, reinforced with a vapor-deposited ceramic coating. This advanced construction delivers true piston-like motion, eliminating the common breakup modes found in standard aluminum domes and extending usable bandwidth well beyond 40 kHz—ideal for today’s high-resolution audio formats. A lightweight Kapton former further enhances performance by increasing power handling while reducing moving mass, ensuring clean, dynamic response even at demanding output levels.
To further enhance performance, the EC30-4 employs a precision-engineered back cup with strategically placed damping materials that effectively dissipate the rear wave, reducing internal resonances and preserving clarity. A copper cap and Kapton former minimize inductance and distortion, allowing for smoother, more detailed playback across the frequency spectrum. Built with an oversized Y35 magnet and treated low-loss cloth surround, the tweeter offers both power and long-term reliability for demanding audio applications.
Built for the Long-Haul
Tipping the scales at nearly 3 lbs, the EC30-4 makes a bold statement in both performance and design. Its rugged 3.6mm aluminum faceplate and sleek honeycomb mesh grill not only ensure rock-solid durability but also exude refined elegance. Perfect for high-end home audio, studio monitoring, or custom speaker builds, this tweeter delivers shimmering treble with uncompromising clarity—engineered for those who refuse to settle for anything less than extraordinary sound.
The EC30-4 delivers an impressively flat frequency response from 800 Hz all the way to 20 kHz, ensuring smooth, natural reproduction across the critical midrange and treble. Its advanced ceramic dome design effectively suppresses resonance, keeping any potential breakup modes well controlled and pushed far beyond the limits of human hearing—remaining tamed below 40 kHz. This extended stability not only preserves accuracy in the audible spectrum but also enhances transient response and overall clarity, making the EC30-4 an ideal choice for applications where precision and detail are paramount.
The EC30-4’s distortion performance reflects the strength of its motor design and careful attention to inductance control. A copper cap on the pole piece works to linearize the magnetic field and reduce inductance modulation, keeping harmonic distortion exceptionally low even as output increases. Combined with an extremely powerful motor structure built around an oversized Y35 magnet, the tweeter maintains tight control over diaphragm motion, preventing unwanted artifacts and preserving fine detail. The result is a smooth, highly resolved top end where second and third harmonic distortion remain well suppressed across the usable bandwidth, allowing subtle nuances and spatial cues to come through with clarity and precision.
The EC30-4 is built for those who want to extract every last bit of accuracy and detail from their system. Its low distortion, powerful motor, and extended bandwidth make it a natural fit for premium 2-way and 3-way designs where clarity, dynamics, and precision take center stage. From compact bookshelf builds to full-scale reference systems, it delivers a clean, effortless top end that reveals nuance without harshness or fatigue. When performance and refinement are non-negotiable, the EC30-4 becomes an obvious choice.
