Dayton Audio Epique E180HE-44

Discover the Epique E180HE-44 - a 6.5" (16.5cm) mid-woofer brought to the world of high-end audio equipment by Dayton Audio. This powerful unit offers class-leading performance with a controlled response. By using their revolutionary MMAG dual-split motor technology, Dayton Audio has developed a mid-woofer that exhibits unprecedented excursion even when pushed to its limits. With its 2x 4 Ohm dual voice coils, the E180HE-44 redefines the concept of power and control in its size, allowing you to create hi-fi audio systems with exceptional precision and fidelity.

• The patented dual-gap MMAG motor design ensures exceptional linearity and minimal distortion
• Lightweight, dampened carbon fiber membrane delivers remarkably consistent reproduction up to 45 degrees off-axis
• Incredibly linear 14mm stroke for class-leading bass extension and control
• Extensive inductance control extends the high frequency range and helps reduce distortion
• Substantial ventilation keeps the voice coil cool and minimizes power compression
• Two 4-ohm voice coils allow for a variety of wiring configurations and flexibility
• Incredible versatility, first-class performance as a subwoofer or woofer in 2-way designs 
  

• The Epique E180HE-44 7" carbon fiber cone woofer from Dayton Audio sets new standards for versatility, distortion and response in small speakers, combining world-class performance with a reasonable price. This dual voice coil driver uses a patented MMAG dual-gap motor assembly for unmatched linear excursion capability to create compact systems with more bass power and lower distortion than ever before. With its carbon fiber cone, dual voice coils, custom-designed suspension, FEA-optimized motor, cast aluminum frame, generous ventilation and extensive induction control, the E180HE-44 sets new standards for 7" driver performance. With exceptional performance spanning from small subwoofers to 2-way designs, this versatile driver will redefine the possibilities of compact speaker systems.
