Combining excellent performance with a reasonable price, the Epique E180HE-44 Carbon Fiber Diaphragm subwoofer sets a new standard for versatility, distortion and response for small speakers. This dual-coil driver uses a patented MMAG dual-gap motor assembly for unmatched linear excursion capability to create compact systems with deeper bass and lower distortion than ever before.

Featuring a carbon fiber cone, dual voice coil, custom surround, FEA optimized motor, cast aluminum frame, large air vents and perfect induction control, the E180HE-44 pushes the limits of a 7" subwoofer.

Flexible surrounds for high linear excursion

When designing the E180HE-44, Dayton Audio paid particular attention to optimizing the surround to ensure unrestricted excursion without limiting performance. The wide-roller rubber surround was custom-machined for high linear excursion, while paying special attention to the profile to avoid limiting off-axis dispersion. A threaded inner edge adds additional damping to the cone while reducing surround reflections to improve high frequency response. A large diameter progressive spider helps maintain diaphragm linearity when pushed to high excursion. In addition, tinsel wires have been woven into the spider on opposite sides to keep the mass and compliance evenly displaced across the spider.

Cast aluminum frame

To support its massive motor assembly while providing a solid mounting surface, the E180HE-44 uses a sturdy cast aluminum frame. The minimalist frame design eliminates unwanted reflections and provides ample airflow to the rear of the diaphragm. With plenty of space behind the spider, the E180HE-44 offers a wide excursion capability. Being a non-magnetic material, the aluminum frame has no effect on the magnetic field, allowing the motor to operate effortlessly. In addition, aluminum is an excellent thermal conductor, making it easy to cool.
