Test Bench: The E180HE-44 Full-Range Subwoofer from the Dayton Audio Epique Line
In this article, Vance Dickason characterizes the E180HE-44 woofer, from the Dayton Audio Epique lineup. As with the E150HE from the same range, the E180HE-44 uses the patented Multiple Magnet Air Gap (MMAG) technology, invented by Enrique Stiles and patented by Step Technologies. The E180HE is a scaled up (7") version of the E150HE, and has a similar feature set but with a secondary magnet system comprised of six ferrite disks, which act as magnetic “diodes” pulling the flux from the main magnet into the top 7mm gap.
