Conventional 2-way designs can cause significant early reflections from their surrounding environment. The E44 and E66 overcome this by positioning a 1.25-inch, silk dome high-frequency driver between two 4.5-inch (E44) or 6.5-inch (E66) midrange drivers. The two smaller woofers work in parallel to partially contain the dispersion of the tweeter, minimizing phase displacement. The result is incredibly detailed stereo imaging.
