Dayton Audio Epique E150HE-44

The  Epique E150HE-44 is a sophisticated 5" (13cm) mid-woofer from Dayton Audio. This innovative mid-woofer is known for its outstanding performance characteristics thanks to its revolutionary MMAG double-slit motor, carbon fiber cone and a maximum excursion of 14 mm. Thanks to comprehensive inductance control and considerable ventilation, the Epique E150HE-44 delivers a smooth reproduction with minimal distortion even when driven to its limits. With its impressive versatility, you are able to develop highly precise and fidelity systems, making it one of the leading concepts in the 5" mid-woofer market.

• 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 E150HE-44 5-1/2" 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-built suspension, FEA-optimized motor, cast aluminum frame, generous venting and extensive induction control, the E150HE-44 sets new standards for a 5-1/2" driver. With exceptional performance ranging from small subwoofers to 2-way designs, this versatile driver will redefine the possibilities of compact speaker systems.
