Epique E150MR-4 5-1/2" Wide-Band Carbon Fiber Midrange Driver 4 ohm The Dayton Audio Epique E150MR-4 Carbon Fiber Midrange Driver sets a new standard for wide-band midrange performance. Built for ultimate transparency, it is engineered with precision using premium materials to deliver exceptional clarity and consistency. The E150MR-4 pairs a lightweight, rigid carbon fiber cone with a titanium voice coil former to ensure fast transient response, low distortion, and stable operation under demanding conditions. Designed for both performance and refinement, it delivers clean, transparent midrange detail that integrates seamlessly into high-resolution loudspeaker systems.
Leave No Doubt Titanium is an ideal voice coil former material for a dedicated midrange driver like the Epique EC150MR-4, offering an excellent balance of strength, low mass, and thermal stability. Its rigidity maintains precise coil alignment during rapid movement, improving transient response while reducing distortion and preserving clarity. High heat tolerance and efficient thermal management reduce power compression, allowing the driver to deliver clean, detailed midrange reproduction even at higher output levels.
The copper cap, aluminum shorting sleeve, and solid aluminum phase plug work together to enhance the performance of the Epique E150MR-4 by reducing distortion and improving clarity. The copper cap and shorting sleeve stabilize the magnetic field, lowering inductance and minimizing modulation for cleaner midrange response. The solid aluminum phase plug improves high-frequency dispersion while aiding heat dissipation, resulting in smoother, more detailed sound and consistent performance.
Damped carbon fiber helps control cone resonances by absorbing unwanted vibrations, keeping the driver’s response smooth and well behaved. Indexing the cone to the surround ensures consistent mechanical alignment, promoting a uniform surface across the cone edge. Together, these design choices reduce diffraction and breakup effects, resulting in a more even frequency response and cleaner midrange detail.

The Dayton Audio Epique family features drivers with a consistent carbon fiber weave, giving a uniform appearance across the lineup. Each driver is designed to deliver the same high-performance sound Dayton is known for, ensuring that whether in midrange, woofer, or tweeter applications, the Epique series maintains clarity, low distortion, and dynamic precision throughout any system.
The Dayton Audio Epique E150MR-4 delivers a smooth, well-controlled response from 100 to 7,000 Hz with efficiency above 90 dB, making it an exceptional choice for dedicated midrange applications. Its advanced carbon fiber cone and refined motor design keep resonances and breakup tightly controlled, preserving accuracy, fast transient response, and outstanding clarity where it matters most. By combining proven Epique technologies into a carefully engineered driver, the E150MR-4 takes much of the complexity out of loudspeaker design—giving you a solid foundation for achieving truly impressive results.
