The heart of the E180HE-44 is the patented MMAG dual gap motor assembly. This unique design uses 2 top plates spaced between 6 smaller gap balancing magnets creating more dynamically stable magnetic gaps with more consistent flux than the more common dual gap arrangements. The combination of the MMAG motor and the underhung voice coil gives the E180HE-44 zero loss of motor force (Bl) even when driven to 10 mm of excursion, and an overall excursion capability of over 14 mm (at 70% Bl). This incredible excursion capability allows extremely low harmonic and intermodulation distortion to ensure remarkably clean output even when driven to high output levels. Furthermore, the motor includes a full length copper sleeve surrounding the pole which offers extensive induction control to lower Le and improve high frequency response, while simultaneously lowering distortion, reducing power compression, and increasing thermal power handling.

Carbon Fiber Is All About Performance Cone View of E180HE-44

The rigid carbon fiber cone gives the E180HE-44 a unique look while offering a number of performance advantages. With one of the highest strength to weight ratios of readily available materials, carbon fiber keeps the moving mass to a minimum enabling extended low frequency extension without sacrificing efficiency. The woven cone has excellent damping properties which keeps unwanted resonances under control for incredibly smooth response all the way up to 3,000 Hz. Optimized cone and dustcap profiles make sure that there is no deformation when exposed to high stress so the smooth response and low distortion remains consistent even when pushed to high output levels. Finally, the outside edge of the cone has been reinforced to further control cone breakup and help maintain controlled off axis dispersion.
